Overview of changes leading to 2.8.1
Tuesday, May 4, 2021
====================================
- Subsetter now fully supports GSUB/GPOS/GDEF tables (including variations); as
such, layout tables are retained by subsetter by default. (Garret Rieger, Qunxin Liu)
- Build scripts no longer check for FontConfig as HarfBuzz does not use it.
- hb-view supports iTerm2 and kitty inline image protocols (Khaled Hosny),
it can also use Chafa for terminal graphics if available (Hans Petter Jansson).
Overview of changes leading to 2.8.0
Tuesday, March 16, 2021
====================================
- Shape joining scripts other than Arabic/Syriac using the Universal Shaping Engine.
Previously these were shaped using the generalized Arabic shaper. (David Corbett)
- Fix regression in shaping of U+0B55 ORIYA SIGN OVERLINE. (David Corbett)
- Update language tags. (David Corbett)
- Variations: reduce error: do not round each interpolated delta. (Just van Rossum)
- Documentation improvements. (Khaled Hosny, Nathan Willis)
- Subsetter improvements: subsets most, if not all, lookup types now. (Garret Rieger,
Qunxin Liu)
- Fuzzer-found fixes and other improvements when memory failures happen. (Behdad)
- Removed most atomic implementations now that we have C++11 atomic impl. (Behdad)
- General codebase upkeep; using more C++11 features: constexpr constructors, etc.

1. Cleaned up (hopefully all) references to licensing to not withstand our
claim that the package is under Knuth license. 2. In many places encoding
of texts changed to UTF-8, to make them easier to read. 3. Functionality
should be same.

* Allow using variable fonts without explicitly specifying any
axis values
* The fontloader has been synced with the context code from
2021-05-20
* Multiple small fixes, mostly concerning discretionaries in harf
mode.
|
|
General:
* Donald Knuth’s changes for his 2021 tuneup of TeX and Metafont are
incorporated (https://tug.org/TUGboat/tb42-1/tb130knuth-tuneup21.pdf). They
are also available on CTAN as the knuth-dist and knuth-local packages. As
expected, the fixes are for obscure cases and do not affect any behavior in
practice.
* Except in original TeX: if \tracinglostchars is set to 3 or more, missing
characters will result in an error, not just a message in the log file, and
the missing character code will be shown in hex.
* Except in original TeX: a new integer parameter \tracingstacklevels, if
positive, and \tracingmacros is also positive, causes a prefix indicating the
macro expansion depth to be output on each relevant log line (e.g., ~.. at
depth 2). Also, macro logging is truncated at a depth ≥ the parameter value.
Aleph: The Aleph-based LaTeX format, named lamed, has been removed. The aleph
binary itself is still included and supported.
LuaTeX:
* Lua 5.3.6.
* Callback for nesting level used in \tracingmacros, as generalized variant
of the new \tracingstacklevels.
* Mark math glyphs as protected to prevent processing as text.
* Removed width/ic compensation for traditional math code path.
MetaPost:
* SOURCE_DATE_EPOCH environment variable support for reproducible output.
* Avoid wrong final % in mpto.
* Document -T option, other fixes to manual.
* Value of epsilon changed in binary and decimal modes, so mp_solve_rising_cubic
works as expected.
pdfTeX:
* New primitives \pdfrunninglinkoff and \pdfrunninglinkon; e.g., for
disabling generation of links in headers and footers.
* Warn instead of aborting when “\pdfendlink ended up in different nesting
level than \pdfstartlink”.
* Dump \pdfglyphtounicode assignments in fmt file.
* Source: poppler support removed, as it was too hard to keep in sync with
upstream. In native TL, pdfTeX has always used libs/xpdf, which is cut-down
and adapted code from xpdf.
XeTeX: Fixes for math kerning.
Dvipdfmx:
* Ghostscript is now invoked safely by default; to override (assuming all
input files are trusted), use -i dvipdfmx-unsafe.cfg. To use PSTricks with
XeTeX, this is required, as in:
xetex -output-driver="xdvipdfmx -i dvipdfmx-unsafe.cfg -q -E" ...
* If an image file is not found, exit with bad status.
* Extended special syntax for color support.
* Specials for manipulating ExtGState.
* Compatibility specials pdfcolorstack and pdffontattr.
* Experimental support for dviluatex’s extended fnt_def.
* Support new feature of virtual font to fallback Japanese font definition.
Dvips:
* Default PostScript document title is now the basename of the input file,
and can be overridden with the new option -title.
* If an .eps or other image file is not found, exit with bad status.
* Support new feature of virtual font to fallback Japanese font definition.

This release fixes a number of small inconsistencies in the STIX Two Math.
The most significant change is that the widths of many of the mathematical
operators and related characters have been revised to be more consistent
with one another.
|
|
New features:
- Compact virtual fonts.
- Add support for the ruby family.
This version requires a new version of DVI driver that supports
new feature of virtual font to fallback Japanese font definition
available in TeX Live 2021.

4.24.4 (released 2021-05-25)
----------------------------
- [subset/instancer] Fixed ``AttributeError`` when instantiating a VF that
contains GPOS ValueRecords with ``Device`` tables but without the respective
non-Device values (e.g. ``XAdvDevice`` without ``XAdvance``). When not
explicitly set, the latter are assumed to be 0.
4.24.3 (released 2021-05-20)
----------------------------
- [otTables] Fixed ``AttributeError`` in methods that split LigatureSubst,
MultipleSubst and AlternateSubst subtables when an offset overflow occurs.
The ``Format`` attribute was removed in v4.22.0.
4.24.2 (released 2021-05-20)
----------------------------
- [ttGlyphPen] Fixed typing annotation of TTGlyphPen glyphSet parameter.
- Fixed two instances of DeprecationWarning: invalid escape sequence.
4.24.1 (released 2021-05-20)
----------------------------
- [subset] Fixed AttributeError when SinglePos subtable has None Value (ValueFormat 0)
4.24.0 (released 2021-05-17)
----------------------------
- [pens] Add ``ttGlyphPen.TTGlyphPointPen`` similar to ``TTGlyphPen``.
4.23.1 (released 2021-05-14)
----------------------------
- [subset] Fix ``KeyError`` after subsetting ``COLR`` table that initially contains
both v0 and v1 color glyphs when the subset only requested v1 glyphs; we were
not pruning the v0 portion of the table.
- [colorLib] Set ``LayerV1List`` attribute to ``None`` when empty, it's optional
in CORLv1.
4.23.0 (released 2021-05-13)
----------------------------
- [designspaceLib] Allow to use ``\\UNC`` absolute paths on Windows.
- [varLib.merger] Fixed bug where ``VarLibMergeError`` was raised with incorrect
parameters.
- [feaLib] Allow substituting a glyph class with ``NULL`` to delete multiple glyphs
.
- [glyf] Fixed ``NameError`` exception in ``getPhantomPoints``.
- [removeOverlaps] Retry pathops.simplify after rounding path coordinates to integers
if it fails the first time using floats, to work around a rare and hard to debug
Skia bug.
- [varLib] Added support for building, reading, writing and optimizing 32-bit
``ItemVariationStore`` as used in COLRv1 table.
- [otBase/otConverters] Add array readers/writers for int types.
- [feaLib] Allow more than one lookahead glyph/class in contextual positioning with
"value at end".
- [COLRv1] Default varIdx should be 0xFFFFFFFF.
- [pens] Make RecordingPointPen actually pass on identifiers; replace asserts with
explicit ``PenError`` exception.
- [mutator] Round lsb for CF2 fonts as well.
4.22.1 (released 2021-04-26)
----------------------------
- [feaLib] Skip references to named lookups if the lookup block definition
is empty, similarly to makeotf. This also fixes an ``AttributeError`` while
generating ``aalt`` feature.
- [subset] Fixed bug with ``--no-hinting`` implementation for Device tables.
The previous code was alwyas dropping Device tables if no-hinting was
requested, but some Device tables (DeltaFormat=0x8000) are also used to encode
variation indices and need to be retained.
- [otBase] Fixed bug in getting the ValueRecordSize when decompiling ``MVAR``
table with ``lazy=True``.
- [varLib/glyf/gvar] Optimized and simplified ``GlyphCoordinates`` and
``TupleVariation`` classes, use ``bytearray`` where possible, refactored
phantom-points calculations. We measured about 30% speedup in total time
of loading master ttfs, building gvar, and saving.
- [subset] Fixed ``AssertionError`` while pruning unused CPAL palettes when
``0xFFFF`` is present.
4.22.0 (released 2021-04-01)
----------------------------
- [ttLib] Remove .Format from Coverage, ClassDef, SingleSubst, LigatureSubst,
AlternateSubst, MultipleSubst.
ATTENTION: This will change your TTX dumps!
- [misc.arrayTools] move Vector to its own submodule, and rewrite as a tuple
subclass.
- [docs] Added a terminology section for varLib.
- [varLib] Move rounding to VariationModel, to avoid error accumulation from
multiple deltas
- [varLib] Explain merge errors in more human-friendly terms
- [otlLib] Correct some documentation
- [varLib/otlLib] Allow merging into VariationFont without first saving GPOS
PairPos2
- [subset] Improve PairPosFormat2 subsetting
- [ttLib] TTFont.save: create file on disk as late as possible
- [cffLib] Add missing CFF2 dict operators LanguageGroup and ExpansionFactor
ATTENTION: This will change your TTX dumps!

cursed_font is a 9x18 bitmapped font designed for low-DPI screens. It was
originally an embiggened and monospace-ified version of Apple's Chicago font
from System 6, but it also takes inspiration from many other fonts such as
bizcat, ttyp0, tamzen, scientifica.

4.21.1 (released 2021-02-26)
[pens] Reverted breaking change that turned AbstractPen and AbstractPointPen into abstract base classes.
4.21.0 (released 2021-02-26)
[feaLib] Indent anchor statements in asFea() to make them more legible and diff-able.
[pens] Turn AbstractPen and AbstractPointPen into abstract base classes.
[feaLib] Added support for parsing and building STAT table from AFDKO feature files.
[instancer] Added option to update name table of generated instance using STAT table's axis values.
[bezierTools] Added functions to compute bezier point-at-time, as well as line-line, curve-line and curve-curve intersections.
4.20.0 (released 2021-02-15)
[COLRv1] Added unbuildColrV1 to deconstruct COLRv1 otTables to raw json-able data structure; it does the reverse of buildColrV1.
[feaLib] Allow sub X by NULL sequence to delete a glyph.
[arrayTools] Fixed Vector division.
[COLRv1] Define new PaintSweepGradient.
[otTables] Moved Paint.Format enum class outside of Paint class definition, now named PaintFormat. It was clashing with paint instance Format attribute and thus was breaking lazy load of COLR table which relies on magic __getattr__.
[COLRv1] Replace hand-coded builder functions with otData-driven dynamic implementation.
[COLRv1] Define additional static (non-variable) Paint formats.
[subset] Added support for subsetting COLR v1 and CPAL tables.
[fontBuilder] Allow setupFvar to optionally take designspaceLib.AxisDescriptor objects. Added new setupAvar method. Support localised names for axes and named instances.
4.19.1 (released 2021-01-28)
[woff2] An initial off-curve point with an overlap flag now stays an off-curve point after compression.
4.19.0 (released 2021-01-25)
[codecs] Handle errors parameter different from 'strict' for the custom extended mac encodings.
[featureVars] Raise better error message when a script is missing the required default language system.
[COLRv1] Avoid abrupt change caused by rounding PaintRadialGradient.c0 when the start circle almost touches the end circle's perimeter.
[COLRv1] Support building unlimited lists of paints as 255-ary trees of PaintColrLayers tables.
[subset] Prune redundant format-12 cmap subtables when all non-BMP characters are dropped.
[basePen] Raise MissingComponentError instead of bare KeyError when a referenced component is missing

This is already in pkgsrc as UnifrakturMaguntia-ttf.
And I imported it there last year.
Seems I liked this font so much I thought it should be in pkgsrc twice!

Closes #414 - increased overlaps of middle glyph for arrow ligatures
Closes #415 - reduces width of macronbelow
Closes #416 - rolls back name ID 4 modification as JetBrains cannot process it correctly
Closes #428 - rolls back variation of the underline to prevent MVAR table generation
Repositioned tilde in related ligatures. Previously it was higher than the standard one.
