can be specified as numbers or percentages now, e.g. `0.5` or `50%`
(Michael Howell).
- #870 - Roll back minimum required version of Pango to 1.46.0
(Kleis Auke Wolthuizen).

With a little bit of help of pin.
==============
Version 2.52.6
==============
Backport a fix from the main branch:
- #599 - Fix incorrect text rendering when text has different scales
in the X/Y axes. This regressed after librsvg 2.52.5, when Pango
had to revert its fix for the same bug. Now librsvg renders all
text as paths, and does the scaling itself. Please file a bug if
you have evidence that this presents a performance problem for you.
==============
Version 2.52.5
==============
Just bugfixes this time:
- #812 - Fix mangled output in rsvg-convert when redirecting output to
a pipe on Windows (Michael Howell).
- #766 - When outputting to SVG, rsvg-convert now uses the
width/height units specified in the command line; it always used
pixels before (Daniel Petri Rocha).
- #814 - Fix incorrect top/left margins for SVG/PS/EPS/PDF output
(Daniel Petri Rocha).
- #599 - Fix incorrect placement of glyphs when text has non-uniform
scaling in the X/Y axes. This is not a librsvg bug, but is fixed by
Pango 1.49.3 and later. Hopefully Pango 1.48.11 will be released
soon with this fix as well. Note that this release of librsvg
cannot increase the minimum Pango version to 1.48.11 because it is
not released yet.
Miscellaneous:
- Updated crate dependencies: assert_cmd, cast, clap cssparser,
float-cmp, itertools, nalgebra, png, proptest, rctree, selectors,
system-deps.
==============
Version 2.52.4
==============
New features:
- #816 - Support the isolation property from the Compositing and
Blending Level 1 specification.
- Support Visual Studio 2022 (Chun-wei Fan).
Fixes:
- #818 - The opacity and mix-blend-mode properties were not being
applied when an element has a mask.
- Fix panic when an empty group has a pattern fill and filters.
- Fix the tests on Windows; the still only work when Fontconfig is
present (Chun-wei Fan).
- Work around a bug in the cairo-rs bindings in the test suite, that
only manifests itself in s/390x due to its calling convention. See
https://github.com/gtk-rs/gtk-rs-core/issues/335
==============
Version 2.52.3
==============
Bugfixes, mostly for text layout. Also, text links in PDF!
- #17 - Support text-decoration=overline.
- #249 - Basic support for the unicode-bidi property. Librsvg still
considers each tspan independently of others, which is incorrect, but
at least bidi-override works now for a single embedding level.
- #804 - Fix placement of tspan that changes the text direction.
- #805 - :lang() selector should now match lang attribute from an
element's parent. (Michael Howell)
- #806 - Fix the text-anchor property for right-to-left text.
- #807 - PDF now includes links inside text elements. (Michael Howell)
==============
Version 2.52.2
==============
Bugfixes and new features!
## New features
Thanks to Michael Howell, rsvg-convert now supports generating
multi-page PDFs in a sensible way.
With one SVG document per page, each page with the
SVG's natural size:
rsvg-convert --format=pdf -o out.pdf a.svg b.svg c.svg
With all pages sized as portrait US Letter, and each SVG scaled to fit
so that there is a 1in margin around each page:
rsvg-convert --format=pdf -o out.pdf \
--page-width=8.5in --page-height=11in \
--width=6.5in --height=8.5in --keep-aspect-ratio \
--top=1in --left=1in \
a.svg b.svg c.svg
Please see the man page for details.
- #738 - Support <a> elements inside <text>. Also, support the CSS :link
pseudo-class for matching against links. (Michael Howell)
- #649 - Support the CSS :lang() pseudo-class for matching against an
element's xml:lang attribute. (Michael Howell)
- #790 - Support the mask-type property from SVG2.
## Fixes
- #800 - Don't panic when a shorthand property is set to
inherit. (Michael Howell)
- #788 - Fix regression with the viewport size of interior <svg>
elements. (Michael Howell)
- #731 - Allow length units to be case-insensitive, per SVG2. (Kolja Lampe)
## Documentation
- There is now a FEATURES.md in the repository, where you can see all
the elements, attributes, and properties that librsvg supports. We
will be adding detail to this gradually.
- For developers, there is now devel-docs/adding-a-property.md with a
tutorial on how to add support for new CSS properties.
==============
Version 2.52.1
==============
This is a bugfix release; there are no new features this time.
## Changes:
- #791 - Fix ordering of tspan inside text elements for right-to-left
languages.
- #789 - Fix text-anchor positioning for right-to-left languages.
- #797 - Fix regression in computing sizes when an SVG has only one of
width/height and a viewBox. Thanks to Joshua Fogg for compiling a
list of test cases for this.
- #565 - Spec compliance - the writing-mode property applies only to
text elements, no to individual tspan elements.
- #794 - Fix build on big-endian platforms.
- Clarify documentation for the rsvg_handle_write() /
rsvg_handle_close() deprecated APIs.
==============
Version 2.52.0
==============
This is a big release! What follows is a summary from the 2.51.x
release notes; you can also read them for more detail.
The biggest user-visible change is that rsvg-convert has been ported
to Rust (Sven Neumann, Paolo Borelli), and it has new features!
## New features in rsvg-convert
### Support for physical units
rsvg-convert is now aware of physical units, and
fixes a bug where PDFs were created at the wrong size. Do you need to
render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
position of a landscape A4 page?
rsvg-convert --format=pdf \
--page-width=297mm --page-height=210mm \
--width=10cm --height=10cm --keep-aspect-ratio \
--top=5cm --left=8cm \
foo.svg > foo.pdf
Please see the rsvg-convert(1) man page for more details and plenty of
examples.
### Support for Accept-Language
Previously, librsvg picked up the user's language preferences through
environment variables like LANG and LC_MESSAGES. This is inconvenient
for applications that call rsvg-convert but don't want to synthesize a
LANG variable.
There is a new option in rsvg-convert so you can pass
--accept-language=<languages> formatted as an HTTP Accept-Language
header. This is used to specify which languages will be chosen from
elements with the "systemLanguage" attribute:
rsvg-convert --accept-language=es-MX,en foo.svg
That command will select Mexican Spanish and English from suitable SVG
elements. Please see the man page for details.
### Miscellaneous
rsvg-convert's default DPI is now 96, to better match W3C
standards. It was 90 before for historical reasons. We can change
this back to 90 if it breaks too many scripts. You can use the
options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
rsvg-convert no longer supports the "xml" or "recording" output
formats. These are useful only for debugging Cairo, not for general
usage.
## SVG2/CSS3 features
The following features are supported now. Madds H, John Ledbetter,
worked on these features.
- transform property from SVG2; previously librsvg only supported the
transform attribute from SVG1.1, which has different syntax.
- context-fill and context-stroke for <marker> and <use> elements.
- markers now support orient="auto-start-reverse".
- paint-order for text elements.
- "auto" values for the width and height attributes of the <image>,
<rect>, and <svg> elements.
- All the <filter-function> types from the Filter Effects Module Level
1 specification: blur(), brightness(), contrast(), drop-shadow(),
grayscale(), hue-rotate(), invert(), opacity(), sepia(), saturate().
- The filter property now supports chains of uri() filters or
<filter-function> shortcuts.
- Support CSS selectors for attribute matching, like rect[attr^="prefix"]
## New APIs
See the HTML documentation for details:
- rsvg_handle_get_intrinsic_size_in_pixels()
- rsvg_major_version / rsvg_minor_version / rsvg_micro_version
variables - used to obtain the librsvg version from languages other
than C, since they do not have access to the C macros like
LIBRSVG_MAJOR_VERSION.
## Deprecations
The following APIs are deprecated but still available:
- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
rsvg_handle_render_element() depending on what you want to do.
Please see the "Migrating from old APIs" chapter in the HTML
documentation for details.
## News for developers
If you want to run the librsvg test suite easily, there are now Docker
scripts to do so. Please see the tools/docker/README.md file for
details. (Madds H)
There is no leftover C code in the library; all of the implementation
and the publically-visible symbols are defined in the Rust code. The
remaining .h files are all public and do not reflect any .c
code. (Sven Neumann)
The test suite is now ported to Rust. The only remaining tests in C
are for the C API itself (tests/api.c). With the test suite in
Rust, the tests are automatically run in parallel across CPU cores,
making test runs much faster. (Sven Neumann, Dunja Lalic)
"cargo build", "cargo test" now work without running autotools first,
so you can in general develop librsvg as a normal Rust project.
The HTML documentation has new chapters; you may find interesting
things there!
## News for distributors
There is a new list of librsvg releases with security fixes in
SECURITY.md. That file also contains security-related information
on librsvg's dependencies.
The Minimum Supported Rust Version (MSRV) is now Rust 1.52.
## Special thanks
Paolo Borelli and Sven Neumann did a lot of painstaking work to finish
porting the library and rsvg-convert to Rust.
Sven Neumann and Dunja Lalic ported the test suite to Rust, making it
much faster.
Dunja Lalic rewrote the Continuous Integration infrastructure, making
it MUCH faster.
Madds H did their Outreachy internship for librsvg and implemented a
bunch of useful SVG2/CSS3 features.
John Ledbetter methodically went through all the <filter-function>
shortcuts and implemented them for SVG2.
Ismael Luceno has been cleaning up our autotools scripts.
Andre Klapper has been wrangling numerous bug reports from Wikimedia
as usual.
Chun-wei Fan, Abraham Toriz, Christian Hergert, Ignacio Casal Quinteiro
have been keeping the Windows and MacOS builds working.
==============
Version 2.51.4
==============
- #618 - SVG2: Implement context-fill and context-stroke for markers
(Madds H).
- #727 - SVG2: Implement paint-order for text elements (Madds H).
- #747 - SVG2: Support width="auto" and height="auto" for the image element.
- Fix the Windows build (Chun-wei Fan).
- The tools/docker directory now has scripts that developers can use
to test librsvg on containers for various Linux distributions.
- Gtk-rs dependency is updated to 0.14.0 (Bilal Elmoussaoui, Chun-wei Fan).
- #758 - Panic when rendering with masks or opacity to a non-image surface.
- #757 - Fix 32-bit builds.
==============
Version 2.51.3
==============
The big news is that rsvg-convert is now aware of physical units, and
fixes a bug where PDFs were created at the wrong size. Do you need to
render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
position of a landscape A4 page?
rsvg-convert --format=pdf \
--page-width=297mm --page-height=210mm \
--width=10cm --height=10cm --keep-aspect-ratio \
--top=5cm --left=8cm \
foo.svg > foo.pdf
Please see the rsvg-convert(1) man page for more details and plenty of
examples.
SVG2 features:
Markers now implement orient="auto-start-reverse". The work on
markers is by Madds H., who is doing their Outreachy internship for
librsvg.
All the <filter-function> types in SVG2 are now supported, thanks to
John Ledbetter.
- The Minimum Supported Rust Version (MSRV) is now Rust 1.52. This
takes care of CVE-2021-28878 in the Rust standard library.
- #514 - rsvg-convert is now aware of physical units.
- #484 - Markers can now have orient="auto-start-reverse" per SVG2
(Madds H - Outreachy internship).
- #711 - Implement the drop-shadow() filter function (John Ledbetter).
- #713 - Implement the hue-rotate() filter function (John Ledbetter).
- #677 - rsvg-convert, do not clip the rightmost/bottomost pixels of
an image with partial pixel coverage.
- Partial fix for #668 - Render small caps for fonts that support the
"smcp" OpenType feature. Librsvg and Pango are not yet able to
synthesize small caps for fonts that do not support them, but for
those that do, they should work fine now.
- #566 - Restrict which elements can appear inside a clipPath, to be
spec compliant.
- #746 - Possible cairo_save() without cairo_restore() in render_layer().
- Various updates to the developer's documentation.
==============
Version 2.51.2
==============
This release fixes an important bug about text spacing. The bug fix
requires an update to at least Pango 1.44. Sorry for the increased
requirements!
Librsvg now supports most of the filter function shortcuts in SVG2;
see below.
Previously, librsvg picked up the user's language preferences through
environment variables like LANG and LC_MESSAGES. This is inconvenient
for applications that call rsvg-convert but don't want to synthesize a
LANG variable.
There is a new option in rsvg-convert so you can pass
--accept-language=<languages> formatted as an HTTP Accept-Language
header. This is used to specify which languages will be chosen from
elements with the "systemLanguage" attribute:
rsvg-convert --accept-language=es-MX,en foo.svg
That command will select Mexican Spanish and English from suitable SVG
elements. Please see the man page for details.
- The Minimum Supported Rust Version (MSRV) is now Rust 1.51.
- Librsvg now requires at least Pango 1.44.
- #730 - Incorrect text spacing when the transform is not 1:1. You
can see this when a small font-size is scaled up due to a
transform. It is less visible for a large font-size scaled down.
- #709 #710 #712 714 #715 #716 #717 - The "filter" attribute now
accepts lists of "<filter-function>" per SVG2. There is support for
blur(), contrast(), grayscale(), invert(), opacity(), saturate(),
sepia() (John Ledbetter).
- #356 - Add --accept-language option to rsvg-convert.
- #704 - Fix circle/ellipse in paths when they are made out of a
single Arc command.
- #691 - Don't allow number lists with unbounded lengths in
tableValues attributes, for feComponentTransfer and
feConvolveMatrix (Madds H).
- #718 - Negative rx/ry in rect element should be ignored.
- #687 - Reduce memory pressure when rendering text.
- Fix build on 32-bit ARM (Lovell Fuller).
- Update the Rust crate dependencies (Bastien Orivel).
- Refactoring parsers (Paolo Borelli).
- There is a new list of librsvg releases with security fixes in
SECURITY.md. That file also contains security-related information
on librsvg's dependencies.
Special thanks to John Ledbetter for carefully implementing each of
the new shortcuts for filter functions in SVG2.
==============
Version 2.51.1
==============
- The Minimum Supported Rust Version is now 1.48.
- rsvg-convert should fully work on Windows again (Abraham Toriz).
- rsvg-convert's SVG output format uses pixel units instead of points again.
- #699 - Images embedded as data: URLs didn't render if they had a
MIME type with a charset parameter.
- #698 - Add limit for too-large radiuses on the feMorphology filter (Madds H).
- #686 - Reduced stack usage (Sebastian Dröge).
- #261 - Parse the enable-background property.
- #703 - Properly ignore elements in an error state inside the "switch" element.
- #695 - Fix cascading mode for the "feImage" element.
- Fix cascading for the "filter" element and filter primitives in general.
- Remove constraints on the types of units used within the "filter"
element and filter primitives.
- Reduced memory consumption in general by about 300 bytes per SVG element.
- Update vulnerable crates:
smallvec to 1.6.1 (RUSTSEC-2021-0003)
generic-array to 0.13.3 (RUSTSEC-2020-0146)
- Lots of cleanups to the build (Sven Neumann).
- Update to gtk-rs 0.9 (Bilal Elmoussaoui).
- Updated ARCHITECTURE.md and documentation in general.
Special thanks to Dunja Lalic for adding the start of code coverage
analysis to the build.
==============
Version 2.51.0
==============
There are many changes in this development release! This experimental
release is meant for early testing, with the understanding that some
things may be broken, especially since we have large changes to the
way librsvg's artifacts are built.
The biggest user-visible change is that rsvg-convert has been ported
to Rust (Sven Neumann, Paolo Borelli).
Please file bugs at https://gitlab.gnome.org/GNOME/librsvg/-/issues/new
if these changes break your scripts; they are experimental for the
2.51.x development series:
- #646 - rsvg-convert's default DPI is now 96, to better match W3C
standards. It was 90 before for historical reasons. We can change
this back to 90 if it breaks too many scripts. You can use the
options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
- rsvg-convert's --export-id (-i) option should now have more useful
behavior. This extracts a particular element from the SVG document
and renders it scaled to the size specified by the --width/--height
arguments, or to the pixel size of the element as if it had no
transformations applied.
- rsvg-convert no longer supports the "xml" or "recording" output
formats. These are useful only for debugging Cairo, not for general
usage.
Known missing features, which should be restored for the stable release:
- rsvg-convert does not allow stdin/stdout streams on Windows; this is
being tracked in issue #676.
The following are changes related to porting to Rust; they are not
necessarily user-visible, but important for developers of the library:
- There is no leftover C code in the library; all of the
implementation and the publically-visible symbols are defined in the
Rust code. The remaining .h files are all public and do not reflect
any .c code. (Sven Neumann)
- The test suite is now ported to Rust. The only remaining tests in C
are for the C API itself (tests/api.c). With the test suite in
Rust, the tests are automatically run in parallel across CPU cores,
making test runs much faster. (Sven Neumann, Dunja Lalic)
- "cargo build", "cargo test" should now work without running
autotools first.
- The C API is now implemented on top of the public Rust API, without
special hooks into the library's internals.
The following APIs are deprecated but still available:
- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
rsvg_handle_render_element() depending on what you want to do.
- These deprecations are because the new APIs conform with the web
world's view of how SVGs should be positioned and scaled in
surrounding content. Whereas the old APIs were about rendering SVGs
to whatever current transformation matrix a Cairo context may
contain, the new APIs take a rectangular viewport and librsvg
automatically scales the SVG document to fit in it. The "natural
sizing" that was implicit in the deprecated APIs is now explicitly
documented, and available through the new API
rsvg_handle_get_intrinsic_size_in_pixels().
New APIs:
- rsvg_handle_get_intrinsic_size_in_pixels() converts an SVG
document's intrinsic dimensions to pixels, i.e. transforms the SVG
document's "width" and "height" attributes to CSS pixels.
New features and bug fixes:
- #615: SVG2: Support a chain of uri() filters in the "filter" property
(John Ledbetter, Sven Neumann).
- #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"]
- #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport.
- Fixed CSS "import" so it allows only files from the same base directory
(Lars Schmertmann).
- #642 - Fix dx/dy offsets in nested <tspan> elements.
- #601 - Compute correct bounds for objects with stroke-width=0.
- Slight speed improvements in the RGBA premultiplication code (Sven Neumann).
- #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and
'css_supported' variables anymore. These variables were hardcoded
to 'true' and unchanged since 2011.
- #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
- Fix the MacOS build (Christian Hergert, Ignacio Casal Quinteiro).
- Deal with missing pkg-config (Ismael Luceno).
- For cross-compilation, check for target-specific prefixed tools like
rustc/cargo (Heiko Becker).
Changes in the Rust API:
- #597 - The LoadingError and RenderingError enums have changed, and
are now marked #[non_exhaustive]. They will probably change again
to hide details of error variants before we make librsvg available
as a crate on crates.io.
Special thanks for this release:
- Dunja Lalic for revamping the CI infrastructure and making our CI
runs much, much faster - !398.
- Sven Neumann, Dunja Lalic for porting the test suite to Rust.
- Sven Neumann, Paolo Borelli for porting rsvg-convert to Rust and
unraveling all the little historical details that were embedded in
it.
- Paolo Borelli for constant refactoring.

|
Version 2.50.3
- #601 - Compute correct bounds for objects with stroke-width=0.
- #545 - Fix MacOS build (Ignacio Casal Quinteiro, Christian Hergert).
- Fix test suite on Rust 1.49 (Sven Neumann).
Version 2.50.2
- #642 - Fix dx/dy offsets in nested <tspan> elements.
Version 2.50.1
- #615: SVG2: Support a chain of uri() filters in the "filter" property
(John Ledbetter, Sven Neumann).
- #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"]
- #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport.
- Fixed CSS "import" so it allows only files from the same base directory
(Lars Schmertmann).
- #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and
'css_supported' variables anymore. These variables were hardcoded

- #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
Version 2.50.0
- The following is a summary of changes between 2.48.x and 2.50.0. For
full details, please see the 2.49.x release notes below.
- This release requires at least Rust 1.40.
- Windows builds now support ARM64, thanks to Chun-wei Fan.
- Librsvg now consumes much less memory for large SVG files. The limit for
the maximum number of elements in an SVG is bigger now at 1 million
elements (this limit exists to avoid unbounded memory consumption by
maliciously large files, and is plenty to render even very detailed
maps). Thanks to Sergey "Shnatsel" Davidoff and Adam Reichold for making
this possible.
- #34 - The 'font' shorthand in is now supported in CSS. Librsvg
ignores the 'line-height' sub-property because it cannot be done
easily with Pango, but everything else in 'font' should work now.
- Many new features from SVG2:
- #508 - radialGradient now supports the "fr" property from SVG2
(Dunja Lalic, Corentin Rossignon).
- #568 - Support href attribute in addition to xlink:href per SVG2.
- #560 - Ignore missing filter references per SVG2.
- #607 - Support the mix-blend-mode property from SVG2 and the
Compositing and Blending Level 1 specification, so layers can be
composited with operators like multiply/screen/color-burn, etc.
https://www.w3.org/TR/compositing-1/ (John Ledbetter).
- #473 - Support the paint-order property from SVG2, so one can pick
the order in which a path's fill/stroke/markers are drawn (John Ledbetter).
- Many bug fixes and little optimizations; see the 2.49.x release notes for
details. Thanks to Paolo Borelli, Daniel Kolesa, Ernestas Kulik.
Sven Neumann, Bastien Orivel, Jordan Petridis, Emile Snyder.
- Special thanks to Sven Neumann for fixing all the cargo-clippy lints.
Version 2.49.5
- #607 - Support the mix-blend-mode property from SVG2 and the
Compositing and Blending Level 1 specification, so layers can be
composited with operators like multiply/screen/color-burn, etc.
https://www.w3.org/TR/compositing-1/ (John Ledbetter).
- #473 - Support the paint-order property from SVG2, so one can pick
the order in which a path's fill/stroke/markers are drawn (John Ledbetter).
- Cleanups of the basic drawing and paint-handling code (Paolo Borelli).
- Many style fixes per cargo-clippy (Sven Neumann).
- Improved documentation on the library's internals.
Version 2.49.4
- Support ARM64 Windows builds (Chun-wei Fan).
- #165 - Draw zero-length paths with square caps correctly (Bastien Orivel).
- #568 - Support href attribute in addition to xlink:href per SVG2.
- #560 - Ignore missing filter references per SVG2.
- #609 - Support the transform attribute again in clipPath (Sven Neumann).
- Update Criterion benchmarks (Ernestas Kulik).
- Update to newer dependencies (Bastien Orivel).
- Many style fixes per cargo-clippy (Dunja Lalic, Sven Neumann).
Version 2.49.3
- #34 - The 'font' shorthand in is now supported in CSS. Librsvg
ignores the 'line-height' sub-property because it cannot be done
easily with Pango, but everything else in 'font' should work now.
- #605 - Compute 'bolder' and 'lighter' font-weight correctly.
- #219 - Make the path parser have a tokenizer/parser (Emile Snyder).
- Fixes for the CI after the gitlab.gnome.org changes (Jordan Petridis).
- Fixed some typos in the documentation (codespell is awesome!).
Version 2.49.2
- Fix failing tests.
Version 2.49.1
- (#604) - Fix build on big-endian machines. Thanks to Daniel Kolesa
for testing this repeatedly.
Version 2.49.0
- Memory consumption of parsed SVG data is greatly reduced. Property
values, path data, and text nodes now use much less memory than
before. Thanks to Sergey "Shnatsel" Davidoff and Adam Reichold for
their contributions.
- With that reduction in memory consumption, librsvg can now load up
to 1 million XML elements. This is a hard limit to avoid malicious
files consuming arbitrary amounts of memory.
- #508 - radialGradient now supports the "fr" property from SVG2
(Dunja Lalic, Corentin Rossignon).
- Sven Neumann has written a fantastic test suite for rsvg-convert(1).
Now we can modify this program with confidence.
- Many, many cleanups (Paolo Borelli).
- #594 - Only compute locale information for elements that need it.
- As usual, thanks to Bastien Orivel for keeping dependent crates updated.
- Fix Windows builds without PangoFT2.
- Benchmarks of internal functions work now. You can run "cargo bench"
in librsvg/ and rsvg_internals/.
Version 2.48.5
- #577 - Support multiple fonts in the font-family property (Bastien Orivel).
Previously in font-family="Foo, Bar, Baz" only Foo would get used.
- #591 - Catch overflow when rendering files with a huge viewBox.
- #593 - Don't panic with an empty objectBoundingBox for a mask.
- #596 - Fix introspection data for rsvg_handle_set_stylesheet (Sutou Kouhei).
- Fixes to the librsvg_crate documentation (Abraham Toriz).
- Loading raster images for inclusion in an SVG and producing
GdkPixbufs is now faster.
Version 2.48.4
- #590 - Fix regression when rendering masks.
- #588 - Fix panic when a big viewBox creates an invalid transform.
- #592 - Fix invalid argument to g_log_structured_array()

Version 2.48.0
- The following is a summary of changes between 2.46.x and 2.48.0.
For full details, please see the 2.47.x release notes below.
- This release requires at least Rust 1.39.
- #379 - New API, rsvg_handle_set_stylesheet(), to set a CSS
stylesheet independent of the SVG document.
- #510 - support opacity in patterns.
- Librsvg's XML parser now supports namespaces (xmlns), and is
stricter than before about it. Files may fail to parse if there are
attributes or elements with namespace prefixes (e.g. foo:bar instead
of plain bar), but without a corresponding namespace declaration
(e.g. xmlns:foo="http://example.com/foo").
This may happen especially with incorrectly-written SVGs that use
xlink:href or xi:include attributes without the corresponding
namespace declarations. If you run into this, just add the
following to your toplevel SVG element:
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xi="http://www.w3.org/2001/XInclude">
^^^^^^^^^ these ones
- Librsvg no longer depends on libcroco, and now does all CSS
processing using Rust crates from Mozilla Servo. As a result,
librsvg can now handle much more complex CSS selectors than before.
- Link-time optimization (LTO) is disabled by default on release
builds, as this increased build time too much. Downstream
distributors may want to turn it back on in the toplevel Cargo.toml.
- #515 (CVE-2019-20446) - Librsvg now has limits on the number of
loaded XML elements, and the number of referenced elements within an
SVG document. This is to mitigate malicious SVGs which try to
consume all memory, and those which try to consume an exponential
amount of CPU time.
- Many bugfixes; please see the 2.47.x release notes below.
Version 2.47.4
- (#240) - Fix rsvg-convert's multipage PDF output when the zoom
option is used (Sven Neumann).
- (#547) - Do not stop rendering if an <image> element references a
nonexistent file. This fixes a number of Open Clipart cases.
- (#558) - Compute the font-size cascade correctly when there are "em"
#and "ex" units involved.
- Updated the man page for rsvg-convert (Sven Neumann).
Version 2.47.3
- #379 - New API, rsvg_handle_set_stylesheet(), to set a CSS
stylesheet independent of the SVG document.
- #510 - support opacity in patterns (Sven Neumann).
- Move away from the Cairo transform type to our own (Paolo Borelli).
- Update the gtk-rs version.
Version 2.47.2
- Handling of the "result", "in", "in2" attributes in filter
primitives is slightly stricter now, and spec compliant. Their
arguments must be of type CSS custom-ident, so "default", "inherit",
"initial", and "unset" are disallowed. Most SVGs should still work
fine.
- #542 - Fix infinite loop when processing CSS sibling combinators.
- #408 - feImage filters no longer clip their output to integer
coordinates.
- #504 - Documentation for the Rust crate (available at
https://gnome.pages.gitlab.gnome.org/librsvg/doc/librsvg/) now has
API usage examples.
- Debug logs from RSVG_LOG=1 should now be more legible and contain
better information on invalid CSS.
- Remove link-time workarounds for Rust pre-1.35 (Kleis Auke Wolthuizen).
- Unify internal error types to share the CSS code with gnome-shell.
- Made handling of XML namespaces more spec-compliant.
- Lots of refactoring to start moving away from Cairo internals
(Paolo Borelli).
Version 2.47.1
- Librsvg no longer depends on libcroco! It now does all CSS
processing using Rust crates from Mozilla Servo; these are also the
crates that are in use in recent versions of Firefox. As a result,
librsvg can now handle much more complex CSS selectors than before.
Fixes #79, #167, #237, #283, #336, #428, #441, #466, #525, #525
(Paolo Borelli, Federico Mena). Thanks to Evgeniy Reizner
for fixing https://github.com/servo/servo/issues/22972, which made
it possible to use Servo's selectors crate.
- #524 - Panic when reading an invalid stylesheet URL in an XML
processing instruction (Paolo Borelli)
- Lots of little improvements to the documentation.
- Link-time optimization (LTO) is disabled by default on release
builds, as this increased build time too much. Downstream
distributors may want to turn it back on in the toplevel Cargo.toml.
- We now have the start of documentation on the library's internals at
https://gnome.pages.gitlab.gnome.org/librsvg/doc/rsvg_internals/index.html
This should be interest of newcomers to librsvg's source code.
Version 2.47.0
- Librsvg's XML parser now supports namespaces (xmlns), and is
stricter than before about it. Files may fail to parse if there are
attributes or elements with namespace prefixes (e.g. foo:bar instead
of plain bar), but without a corresponding namespace declaration
(e.g. xmlns:foo="http://example.com/foo").
This may happen especially with incorrectly-written SVGs that use
xlink:href or xi:include attributes without the corresponding
namespace declarations. If you run into this, just add the
following to your toplevel SVG element:
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xi="http://www.w3.org/2001/XInclude">
^^^^^^^^^ these ones
- Patterns and gradients reused across more than one element will only
get resolved once now; this should make things marginally faster for
patterns or gradients with fallbacks.
- #515 (CVE-2019-20446) - Librsvg now has limits on the number of
loaded XML elements, and the number of referenced elements within an
SVG document. This is to mitigate malicious SVGs which try to
consume all memory, and those which try to consume an exponential
amount of CPU time.
- #521 - Compute geometries correctly if there is a viewBox attribute.
- #308 - Fix stack exhaustion with circular references in <use> elements.
- Consistently use the LGPL 2.1 wherever it is mentioned.
- Patterns and gradients reused across more than one element will only
get resolved once now; this should make things marginally faster for
patterns or gradients with fallbacks.
- #506 - Fix empty patterns which reference a fallback pattern with
children.

Changelog:
Version 2.46.0
- The following are highlights compared to the 2.44.x series. For
full details, please see the release notes for the 2.45.x series.
- All of librsvg.so is now implemented in Rust! That is, except for a
very thin wrapper over the public API functions. Hopefully we can
remove this wrapper when Cargo gets some more features around
controlling the linking step. This release requires at least Rust 1.34.
- Librsvg now comes with a Rust crate that can be used from Rust
applications. See librsvg_crate/examples. This Rust API is
designed to be idiomatic; if you want a Rust binding to the shared
library instead, please use the "rsvg-rs" crate from crates.io.
- The following API functions are new in the C library:
rsvg_handle_get_intrinsic_dimensions()
rsvg_handle_render_document()
rsvg_handle_render_layer()
rsvg_handle_render_element()
rsvg_handle_get_geometry_for_layer()
rsvg_handle_get_geometry_for_element()
Correspondingly, there is a new chapter in the documentation, called
"Recommendations for Applications". These new APIs conform better
with the web platform's idea of how SVG sizing/positioning should
work. Applications should now find it easier to scale and render
SVGs in a single call, instead of having to obtain image dimensions
first.
- A bunch of functions have been deprecated but are still available:
- rsvg_handle_write()/close() are deprecated in favor of the
stream functions. Unfortunately the write()/close() pair
require buffering the entire document, in case it is a .svgz
compressed file; the streaming functions do not have this
problem.
- Functions that return RsvgDimensionData and RsvgPositionData are
deprecated, since they just use integers instead of floating
point numbers. They are replaced with the _get_geometry_*()
functions above.
- The library is a lot more strict now in terms of detecting that the
API functions are called in the correct order. For example, calling
rsvg_handle_get_dimensions() before rsvg_handle_close() will now
emit a critical warning.
- Librsvg is gradually moving towards using code from Mozilla's Servo.
We haven't quite gotten rid of libcroco and libxml2 yet, but this is
in progress.
- Many thanks to all the people who participated in the long cycle for
2.45. Having the whole library's functionality in Rust is a big
accomplishment!
Version 2.45.92
- #496 - Ensure all lengths and angles parse as finite numbers
- #497 - Don't panic on paths with all-invalid commands
- #500 - Added additional SVG blend-modes for the feBlend filter primitive (Andargor)
- Some changes in the build structure to allow for faster builds.
Version 2.45.91
- The documentation has a new chapter, Recommendations for Applications.
- #451 - Make rsvg-convert detect images larger than pixman's limit.
- #410 - Update introspection annotations.
- #449 - librsvg_crate: Make cancellable arguments consistent with gio-rs
- librsvg_crate: Take all gio arguments as IsA<SomeGioType> generics
- Updated Rust crates to avoid duplicates (Bastien Orivel)
Version 2.45.90
- New API functions:
rsvg_handle_render_document()
rsvg_handle_render_layer()
rsvg_handle_render_element()
rsvg_handle_get_geometry_for_layer()
rsvg_handle_get_geometry_for_element()
CairoRenderer in the librsvg_crate has corresponding functions
as well.
- Fix builds with gettext ≥ 0.20 (Ting-Wei Lan).
- If the C API is called out of order, downgrade hard panics to
g_critical() to cope with incorrect/old applications that called
rsvg_handle_get_dimensions() before rsvg_handle_close().
- API reference documentation is much improved.
Version 2.45.8
- This version requires at least Rust 1.34.
- #485 - Fix build on Rust earlier than 1.36 (Kleis Auke Wolthuizen).
- More polishing of the Windows build (Chun-wei Fan).
- Update gtk-rs and dependent crates (Bastien Orivel)
Version 2.45.7
- Fix #463 - Don't panic if an SVG has character data outside the
first element.
- Fix #467: Don't panic when there's an xi:include fallback with no
parent element. Thanks to Bastien Orivel for running afl-fuzz
on librsvg.
- Fix #471: Fix blurry semi-opaque objects when rendering with a
scaled transformation. Thanks to the gnome-games people for
isolating a test case and to Evgeniy Reizner for providing a more
minimal one.
- Fix #481: Don't ignore the first x/y/dx/dy in text/tspan elements if
there is more than one position specified.
- #452 - In librsvg_crate, SvgHandle now has a ::has_element_with_id()
method.
- rsvg-convert now catches the case where the SVG has no dimensions.
- Replaced the Visual Studio build infrastructure for NMake
(Chun-wei Fan).
- This version no longer contains the rsvg-view program, so librsvg no
longer depends on GTK. Please see
https://people.gnome.org/~federico/blog/removing-rsvg-view.html for
the rationale behind this change.
- The poly element no longer supports "verts" as an alias for the
"points" attribute. The "verts" name was only used in SVG pre-1.0,
and we had been cargo-culting that name ever since.
- We now use more machinery from Mozilla Servo, in this case the
markup5ever and rust-selectors crates. This is in line with
gradually replacing libcroco with a Rust-only CSS machinery.
- Lots and lots of refactoring and cleanups: use the rctree crate
instead of our own tree representation; remove interior mutability
in element structs; make the gradients and patterns code less
repetitive (Paolo Borelli).
- Update some dependencies (Bastien Orivel).
- New section in COMPILING.md about cross-compilation to Windows using
mingw (Takuro Ashie)
- Fix static linking and Windows builds (Kleis Auke Wolthuizen).
Version 2.45.6
- Librsvg now requires Rust 1.30.0 or later.
- Librsvg now requires Cairo 1.16.0 or later. Thanks to
Julian Sparber for keeping up with cairo-rs API changes.
- This version introduces librsvg_crate, an idiomatic Rust crate for
using librsvg from Rust programs directly, without using GObject
machinery. This API is subject to change, but you can start using
it now in an experimental fashion. Thanks to Paolo Borelli and
Jordan Petridis for fine-tuning this new API.
- All of the librsvg internals are now in Rust! The C code is just a
thin wrapper over Rust functions.
- The internals library has been converted to Rust 2018 (Jordan Petridis).
- Within librsvg_crate, there is a new infrastructure for doing
reftests in Rust, that does not depend on PNG reference files. See
librsvg_crate/tests for details.
- This release introduces the following new APIs:
rsvg_handle_get_intrinsic_dimensions(),
rsvg_handle_get_geometry_for_element().
- Parsing of the "style" attribute, which has a plain list of CSS
property declarations, is now done with rust-cssparser.
- CSS selector matching should be marginally faster than before.
- Fix Visual Studio builds (Chun-wei Fan).
- Fix #11 - Respect the "direction" property for bidirectional text (Khaled Hosny).
- Fix #295 - Ensure the initial viewport fits into temporary surfaces for compositing
- Fix #425 - Don't fail parsing if the system's locale is broken (Paolo Borelli).
- Fix #438, #443 - Don't create intermediate raster surfaces unless
absolutely needed. This was causing blurred output for SVGs from
Inkscape and Illustrator, since they include an "enable-background"
property even when there are no filters in use. Thanks to Julian
Sparber, Jordan Petridis, Zeeshan Ali for doing a huge "git bisect"
to find the cause of this bug.
- Fix #443 - Fix blurry output when enable-background is used without filters.
- Fix #455 - Fix rounding error on i386 (Olivier Tilloy).
- Check for Cairo errors when constructing paths.
Version 2.45.5
- At build time, you can now pass $CARGO and $RUSTC environment
variables if you need to override the default Rust toolchain.
Please see COMPILING.md for details. (Tobias Kortkamp)
- Fix #405 - In the gdk-pixbuf loader, don't crash if the write()
function doesn't receive a GError.
- Fix #268 - Remove the comp-op property; it's not in SVG 1.1 nor SVG 2.
- Fix #415 - register RsvgHandleFlags and the RsvgError enum values in
a thread-safe fashion (Sebastian Dröge).
- All of the library's non-GObject functionality is implemented in
Rust now.
- Update the cairo crate (Kornel Lesiński).
- Clean up the loading code paths (Paolo Borelli).
- Updated compilation docs for Debian (Jordan Petridis)
- Updated parts of the reference documentation.
Version 2.45.4
- Brown paper bag release, my apologies.
- Fix #402 - Fix the library's soname. Thanks to Gabriele Balducci
for reporting it, and Kalev Lember for fixing it.
Version 2.45.3
- Big news! All the real work in the library is now implemented in
Rust. The public API is implemented in C, but most it calls
immediately into the Rust code. Special thanks to Paolo Borelli and
Carlos Martín Nieto for making this possible.
- rsvg_handle_set_base_uri() now really assumes that it is passed a
URI. Previously it would try to differentiate between real URIs,
and absolute or relative file paths. If this breaks your code
(i.e. you are passing a filename, not a URI), please tell us so we
can restore the old behavior!
- Fix #395 - Don't panic in feMorphology if it ends up with a negative
scaling transformation.
- Fix #398 - Detect circular references in gradients.
- Match the Firefox/Chrome behavior on gradients and patterns with
circular references for fallbacks (Paolo Borelli).
- Fixes for Rust 1.30 and below (Jordan Petridis).
- Lots and lots of refactoring (Paolo Borelli, Federico Mena).
Version 2.45.2
- rsvg_cleanup() is now deprecated. This was only meant to be called
from code to be checked by Valgrind. Leak checkers may show
reachable memory from libxml2; real memory leaks should still be
reported, of course. (Kornel Lesiński).
- As an experimental change, librsvg no longer calls xmlInitParser()
from libxml2. Please tell us if this causes problems for
multithreaded programs.
- Added g_warning()s to ensure the API is called in the correct
sequence.
- The text handling code has been completely refactored and
simplified. This will allow us to implement the x/y/dx/dy
properties for multiple glyphs in the future. Please report any
problems you experience in text rendering.
- Fix #385 - Don't crash if there is no rsvg_handle_write() before
rsvg_handle_close().
- Fix #391 - Avoid undefined behavior when casting opaque pointers
(Jordan Petridis).
- Fix crash when a linear RGB filter is followed by an SRGB filter
(Ivan Molodetskikh).
- Fix #393 - Stack overflow when freeing thousands of sibling elements.
- Fix positioning of adjacent <tspan> elements.
- All the toplevel loading and drawing code is implemented in Rust now.
- Pixbuf conversion code is in Rust now (Paolo Borelli).
- Cleanups in the code for XML processing, markers, attributes (Paolo
Borelli).
- Many build/link fixes (Jordan Petridis).
- Cleanups in the code that calls libxml2 (Kornel Lesiński).
Version 2.45.1
- New public API, rsvg_handle_get_geometry_sub(), to get the exact
geometry of an element. The functions
rsvg_handle_get_position_sub() and rsvg_handle_get_dimensions_sub()
are deprecated now; these returned incomplete data with integer
coordinates (Julian Sparber).
- rsvg_handle_write() and rsvg_handle_close() are now deprecated in
favor of the functions which use a GInputStream. The former need to
buffer the entire SVG data first; the latter don't need buffering.
- Librsvg no longer tries to load XML entities which reference
external resources, either parameter or general entities, declared
in the DTD. This never worked properly, and it is better to do so
via the xi:include mechanism. Also, unparsed external entities with
a notation are not really supported in SVG; it has its own <image>
element and similar for that purpose. Only internal general
entities are supported now, for example:
<!ENTITY foo "<some xml here>">
<!ENTITY bar "some text here">
- Started support for localized error messages (Daniel García Moreno).
- Ported to Rust: loading code, XML processing code, data: URL parsing,
- Many code cleanups and refactorings, courtesy of Paolo Borelli.
- Fix undefined behavior in casts (Jordan Petridis).
- Cairo/Rust API updates by Julian Sparber.
- configure.ac cleanups by Maya Rashish.

feConvolveMatrix (Ivan Molodetskikh).
- Fix #363 - Don't drop spaces around <tspan> elements.
- Fix #365 - rsvg-convert now uses pixel units for SVG output, instead
of points. This requires cairo 1.15.12 (Antonio Ospite).
- Fix #358, #366 - tweaks to have the test suite pass on i386 and
non-x86_64 platforms (Simon McVittie, Federico Mena).
- Fix #368 - With RSVG_LOG=1, librsvg will now report when SVGs have
references to nonexistent elements, to aid debugging (for example,
in an xlink:href attribute).
- Fix #371 - rsvg-convert was positioning extracted elements
incorrectly when using the -w/-h options together with --export-id.
- Fix #372 - Mis-rendering in small arc segments.
- Fix #373 - Rendering of gradients for horizontal/vertical stroked
lines with gradientUnits="userSpaceOnUse".
- Fix a couple of memory leaks in the error paths of the GdkPixbuf
loader (Benedikt Heine).
- Allow reference tests with a small difference to pass without
breaking the build (Simon McVittie).
- CSS processing code is now in Rust, although it still calls libcroco
to do the parsing.
- XML processing code is partially moved to Rust, although it still
calls libxml2 for the XML parsing.
- Special thanks to Alex Crichton for ensuring that MacOS builds work.

Alternatively the package could be updated to 2.46.0 but I don't have
time to deal with any potential fallout right now.

This package now uses rust. The user-settable variable LIBRSVG_USE_RUST
allows switching between this and the (obsolete) plain-C version
in librsvg-c. It defaults to "yes" on platforms that lang/rust currently
supports.

- Fix #325 - All the elements were being leaked at the toplevel.
- Fix #326 - Fix COMPILING.md - librsvg 2.44 does not build on Ubuntu
18.04 because it has a rust version that is too old.
Version 2.44.0
- Librsvg now has minimal logging for debugging by setting the
RSVG_LOG environment variable. See CONTRIBUTING.md for details.

addition to lengths (Paolo Borelli).
- Fix #318 - the font-weight property was being parsed incorrectly.
- Fix #323 - don't use 100% "forever" with malicious SVGs that cause
an exponential number of elements to be instanced through the
<use> element. We limit the number of <use> instances now.

- We now require Rust 1.26.
- We now include Rust debug information even in release builds, to make it
easier to obtain stack traces.
- Fix #310 - Respect DPI in the font-size property (Mike Marcacci).
- Fix: draw the circle/ellipse elements with the same orientation as
the SVG 1.1 test suite; this is relevant for stroke-dasharray (Ivan
Molodetskikh).
- Refactoring of the drawing code and font sizes (Paolo Borelli).
- New filters in Rust: feConvolveMatrix, feColorMatrix, feMorphology,
feDisplacementMap, feGaussianBlur, feDistantLight, feSpotLight,

amount of work! (Paolo Borelli)
- All the style property parsers have been moved to rust-cssparser.
Version 2.43.0
- This is the start of the 2.43 development series, and you bet we are
doing extensive changes!
- Many, many thanks to Jordan Petridis for keeping our Continuous
Infrastructure updated all the time, and for emergency fixes when
they were necessary.
- As part of the Summer of Code 2018, Ivan Molodetskikh is porting the
filter effects to Rust. These are done so far: core filters
infrastructure, feComposite, feMerge, feOffset. The only remaining
SVG elements done in C pertain to filter effects, and Ivan is taking
care of them.
- The feComposite filter now operates in linear RGB space, for better
spec compliance. We transform back to SRGB for the final results
(see issue #275 for pending work on fully supporting this
elsewhere).
- Filters now compute their bounds to floating-point values, instead
of clipping them to integers.
- The text, tspan, tref elements are now in Rust (Paolo Borelli).
- Text rendering should be better. We now perform text measurement
operations with the actual affine transformation that the text will
use in the end. This should give Pango/Freetype a better chance of
doing scale-appropriate hinting.
- The basic styling infrastructure has moved to Rust (Paolo Borelli,
Federico Mena). We don't use the old and limited cascading code
anymore. We also audited which CSS properties are supposed to
inherit automatically or not; this should be working per the SVG
spec now. Special thanks to Paolo for doing the largest part of the
work in moving the style data to Rust; this was a painstaking,
months-long process of constant refactoring.
- The internals of the drawing infrastructure and bounding-box
computation are now done in Rust (Paolo Borelli).
- Element creation from the parsing stage is now in Rust (Saurav
Sachidanand).
- Clipping and Masking are now done in Rust (Paolo Borelli).
- Our tests now include the full Adwaita icon theme, so it doesn't
break.
- Fix: #241 - feDistantLight and feSpotLight now work again.
- Fix: #282 - feComposite is fixed not to overwrite the source image
in some cases; this fixes drop shadows generated from Inkscape (Ivan
Molodetskikh).
- We have the beginnings of Windows CI, courtesy of Guillaume Gomez.
- Changes from 2.42.4:
- Fix: elements with systemLanguage attributes without variants now
work better (Paolo Borelli).
- gitlab#227 - Fix: we now catch negative values in stroke-dasharray
properties instead of leaving the cairo_t in an error state.
- gitlab#228 - Fix: empty transform attribute now correctly yields an
identity transform (Dmitry Kontsevoy).
- Fix possible crash on invalid gradient references.
- Make robust against patterns and gradients with no children.
- Lots of code cleanups and refactorings (Jordan Petridis, Dmitry
Kontsevoy, Ivan Molodetskikh).
- Code moved to Rust: low-level path and PangoLayout drawing, "switch"
element (Paolo Borelli).
- New Rust dependencies: float_cmp, pangocairo crates.
- We now require Rust 1.21 or later.
- Changes from 2.42.5:
- #276 - rsvg_handle_render_cairo() will now refuse to render if the
cairo_t passed to it is in an error state. Fixes a panic in the
cairo-dock program.
- #206 - The test suite now writes test artifacts to tests/output
instead of /tmp (Saurav Sachidanand).
Version 2.42.3
- gitlab#205 - The configure script now checks for Rust 1.20.0 -
previously this minimum requirement was not well-defined.
- gitlab#204 - New feature: If an SVG has an <a> link element, we now
generate the corresponding link when outputting to a Cairo PDF
surface. If you use rsvg-convert(1) with PDF output, <a> links in
the SVG will work in the PDF (Dmitry Kontsevoy).
- gitlab#108 - New feature: support font-size:larger and font-size:smaller
relative sizes.
- New feature: rsvg-convert now supports SOURCE_DATE_EPOCH per
https://reproducible-builds.org/specs/source-date-epoch/ to generate
reproducible output for PDFs (Chris Lamb).
- gitlab#197 - New requirement: We now require Freetype2 2.9.0, which
fixes font rendering bugs. The test reference PNGs have been
regenerated with this version. You may see changes in font
rendering as a result of this updated requirement.
- gitlab#91 - Fix rendering of masks and clips when the initial
transformation has a translation component (Massimo).
- gitlab#112 - Fix: apply style attributes for all SVG elements, not just
for the toplevel one.
- gitlab#161 - Fix the marker angle for the last vertex of closed
paths (Juraj Fiala).
- gitlab#198 - Fix: Make rsvg_pixbuf_from_file() and its derived
functions work again. Now we have tests for the whole public API.
- gitlab#143 - Minor optimizations for Gaussian blurs (Timm Bäder).
- gitlab#201 - Minor speedups in the code to parse SVG attributes.
- gitlab#178 - Fix some tests that failed on 32-bit machines.
- COMPILING.md now lists our build dependencies, and has command lines
which you can use on openSUSE/Fedora/Debian/Ubuntu/MacOS to set up a
development environment for librsvg (Jordan Petridis, Brion Vibber).
- gitlab#211 - Running the configure script on MacOS now works and
doesn't try to use -Bsymbolic for linking (Brion Vibber).
- gitlab#In addtion to --enable-debug/--disable-debug to control the Rust
compilation, now you can use an environment variable
LIBRSVG_DEBUG=yes / LIBRSVG_DEBUG=no if you wish.
- Code moved to Rust: SVG paint servers (Dmitry Kontsevoy), SVG
attribute parsing.
- We now use a Cargo workspace internally, to move more things to Rust
(Jordan Petridis, Chun-wei Fan).
- Special thanks in this release to Jordan Petridis for MAJOR
improvements to our Continuous Integration infrastructure, the
repository structure, and updates to the compilation documentation.
Also for setting up 32-bit builds for continuous integration.
Version 2.42.2
- gitlab#193 - Don't crash when feConvolveMatrix doesn't specify
orderx/ordery attributes.
- gitlab#136 - Parse stroke-dasharray property correctly. This code
is in Rust now; yay! (Jordan Petridis).

file with a UNC path for a paint server (i.e. don't try to load it at all).
- We now support cross-compilation of the Rust code (David Michael).
See COMPILING.md for details.
- Fixed bugs from Coverity runs (Philip Withnall).
- Vastly improved README.md, new COMPILING.md, improved CONTRIBUTING.md.

Version 2.41.1
- The feConvolveMatrix filter primitive wasn't being rendered at all;
now it works.
- Pattern specifications can now have a fallback color, per the spec -
https://www.w3.org/TR/SVG/painting.html#SpecifyingPaint
- Tests now use a very basic form of reproducible font rendering.
This means that "make check" should pass even if you have a custom
Fontconfig setup.
- Fixed recursive fallbacks in gradients.
- Per the spec, we now don't render elements which have invalid
attributes.
- Windows build: support building with Fontconfig; support Visual
Studio 2017; generate .pc files upon install (Chun-wei Fan)
- Fixed bgo#621088 - Text elements can now be used as clipping paths.

for an intermediate result.
- Update for bgo#778666 - Use our own thumbnailer specification file
(Jeremy Bicha).

- Fix parsing of "azimuth", "elevation", "limitingConeAngle" for
filter effects.
- Fixed bgo#785276 - Don't crash on empty or single-byte files.
- Made the <switch> element work; SVG feature names were being
tested incorrectly.
- Fixed a few cases of uninitialized struct fields.
- Code converted to Rust: preserveAspectRatio attribute, viewBox
attribute, core Node structure, path/line/rect/circle/ellipse basic
shapes, group/defs/switch/svg/use/symbol structural elements, pattern element

code converted to Rust.
- We now require cairo-rs 0.2.0

using "cargo vendor". Linux distros can replace these dependencies
with their own versions using the infrastructure described in
http://doc.crates.io/source-replacement.html
Version 2.41.0
- The big news is that parts of librsvg are now implemented in the
Rust programming language, instead of C. The public API remains
identical. Rust should provide us with memory safety and nicer
built-in abstractions for the code, as well as an easier way to do
unit tests. Special thanks to all the people who sent tips on Rust
idioms, and to Sebastian Dröge and Hubert Figuière for the Automake bits.
- Added an "--enable-debug" option to configure.ac - this will tell
the Rust compiler to generate debugging code, instead of working in
release mode. Note that you must still pass CFLAGS by hand by the
regular means for the C code.
- For Windows builds, only MSVC 2012 and upward are supported now.
- Chun-wei Fan made it possible to regenerate the MSVC project files
when Makefile.am changes.
- Fixed bgo#763386 - handle curveto segments where three control
points are coincident. Thanks to Massimo for the detailed test cases.

mask. Thanks to Mike Lewis for the patch.
- Fixed bgo#776297 - Only render markers in path, line, polygon,
polyline elements.
- Fixed feImage filters when they reference SVG nodes; they were
translated incorrectly.
- Fixed feComponentTransferFunction when there are duplicated feFuncX
elements.
- Fixed bgo#761871 - handle reflection points for quadratic and cubic
curves correctly.
- Fixed bgo#686953 - support the "marker" shorthand property.
- Fixed a few minor issues pointed out by Coverity.
- The path data parser now handles boolean values in Arc elements correctly.
- Fixed conformance bugs in gradient inheritance.
- Radial gradients now adjust the focus point correctly to be within
the gradient's radius.
- Stroke width normalization is now conformant to the spec.
- Viewport-relative length normalization is now conformant to the spec.
- Added some of the official SVG 1.1 test files to our test suite. Fixed
a little bunch of conformance bugs.
- As a small optimization, we only push/pop CSS states when rendering
will actually happen, instead of for all (potentially invisible) nodes.
- Code that has been converted to Rust: marker orientations and
rendering, path data parser, path building, length normalization,
gradient inheritance, bounding boxes with affine transformations.
- Lots of refactoring to accomodate the Rust code, and general cleanups as well.
- Added tests/README.md with instructions on how to run the test suite
and update it.
rsvg-test can now skip files or directories that start with "ignore".
- Improved the README.
