# General improvements
The Octave plotting system now supports high resolution screens, i.e., those with greater than 96 DPI which are referred to as HiDPI/Retina monitors.
Unicode character support for files and folders in Windows.
A new core function movfun will apply a function to a sliding window of arbitrary size on a dataset and accumulate the results. Many common cases have been implemented using the naming scheme movXXX where XXX is the function that will be applied. For example, the moving average over a dataset is movmean. New moving window functions:
movfun movslice movmad movmax movmean movmedian movmin movprod movstd movsum movvar
The fsolve function has been tweaked to use larger step sizes when calculating the Jacobian of a function with finite differences. This leads to faster convergence.
The ranks function has been recoded for performance and is now 25X faster. In addition, it now supports a third argument that specifies how to resolve the ranking of tie values.
The function randi has been recoded to produce an unbiased (all results are equally likely) sample of integers. This may produce different results in existing code. If it is necessary to reproduce the exact random integer sequence as in previous versions use
ri = imin + floor ((imax - imin + 1) * rand ());
The function isdefinite now returns true or false rather than -1, 0, or 1. To test for a positive semi-definite matrix (old output of 0) check whether the following two conditions hold:
isdefinite (A) => 0 and isdefinite (A + 5*TOL, TOL) => 1
The intmax, intmin, and flintmax functions now accept a variable as input. Existing code to query the range of an existing variable can be simplified by removing the call to class that was previously required. For example defining the variable x = int8 (3) in the workspace, calls like
range = [ intmin(class(x)), intmax(class(x)) ]
can in Octave 5 be simplified to range = [ intmin(x), intmax(x) ].
The path handling functions no longer perform variable or brace expansion on path elements and Octave’s load-path is no longer subject to these expansions.
A new printing device is available, "-ddumb", which produces ASCII art for plots. This device is only available with the gnuplot toolkit.
# Dependencies
The GUI requires Qt libraries. The minimum Qt4 version supported is Qt4.8. Qt5 of any version is preferred.
The OSMesa library is no longer used. To print invisible figures when using OpenGL graphics, the Qt QOFFSCREENSURFACE feature must be available and you must use the qt graphics toolkit.
The FFTW library is now required to perform FFT calculations. The FFTPACK sources have been removed from Octave.
Matlab compatibility
* Many improvements.

Remove hack that had a high chance of resulting in a dysfunctional package
qttools can't be a build dependency because we link against something
in it.

Summary of important user-visible changes for version 4.4 (2018-04-30):
----------------------------------------------------------------------
** A graphical Variable Editor has been added to the GUI interface.
It uses a spreadsheet-like interface for quick, intuitive editing
of variables. The Variable Editor is launched by double-clicking
on a variable name in the Workspace Window or by typing
"openvar VARIABLE_NAME" in the Command Window.
** On systems with 64-bit pointers, --enable-64 is now the default and
Octave always uses 64-bit indexing. However, if the configure
script determines that the BLAS library uses 32-bit integers, then
operations using the following libraries are limited to arrays with
dimensions that are smaller than 2^31 elements:
BLAS LAPACK QRUPDATE SuiteSparse ARPACK
Additionally, the following libraries use "int" internally, so
maximum problem sizes are always limited:
glpk Qhull
** The octave command no longer starts the GUI by default. Most users
starting Octave from a shell were expecting the command line
interface, and desktop launchers already required the `--force-gui'
option. With this change, desktop launchers should be modified to
use the new option `--gui'. The previous `--force-gui' option will
continue to work, and maps to `--gui', but it will be removed in
Octave 6.
** A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is
addressed by limiting GUI sub-panel relocation capabilities for Qt
versions in the range >= 5.6.1 and < 5.7.1. However, this may not
thoroughly avoid issues on all platforms.
** A new container data type--containers.Map--is available. Map is a
key/value storage container (a.k.a, a hash) that efficiently allows
storing and retrieving values by name, rather than by position which
is how arrays work.
** The bareword "import" is now recognized in scripts and functions.
However, the functionality to import functions and classes from
other namespaces into the local scope has not yet been implemented.
Attempting to use "import" will provoke an error message.
** hex2num and num2hex now work for integer and char types and num2hex
may optionally return a cell array of strings instead of a character
array. If given a cell array of strings, hex2num now returns a
numeric array of the same size as the input cell array. Previously,
hex2num would accept a cell array of strings of arbitrary dimension
but would always return a column vector.
** New special functions cosint, sinint, and gammaincinv have been added.
** Special functions in Octave have been rewritten for larger input
domains, better accuracy, and additional options.
* gammainc now accepts negative real values for X.
* improved accuracy for gammainc, betainc, betaincinv, expint.
* gammainc has new options "scaledlower" and "scaledupper".
* betainc, betaincinv have new option "upper".
** The "names" option used in regular expressions now returns a struct
array, rather than a struct with a cell array for each field. This
change was made for Matlab compatibility.
** The quadcc function now uses both absolute tolerance and relative
tolerance to determine the stopping criteria for an integration.
To be compatible with other quadXXX functions, such as quadgk, the
calling syntax has changed to
quadcc (f, a, b, [AbsTol, [RelTol]])
To update existing code, change instances of RelTol to [0, RelTol].
quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol])
A warning that a single tolerance input is now interpreted as an
absolute tolerance will be issued in Octave versions 4.4 and 5,
after which it will be removed. The warning has ID
"Octave:quadcc:RelTol-conversion" and can be disabled with
warning ("off", "Octave:quadcc:RelTol-conversion")
** The qr function now returns a standard factorization unless
explicitly instructed to perform an economy factorization by using a
final argument of 0.
** The Qt graphics toolkit now supports offscreen printing without osmesa
if Octave was built with Qt >= 5.1.
** The built-in pager for display of large data is now disabled by
default. To re-enable it for every Octave session add the following
to your .octaverc file:
more on;
** The FLTK toolkit is no longer prioritized for development. The
number of Octave Maintainers is too small to support three different
graphic toolkits. New development will target the Qt toolkit.
While no longer prioritized, the FLTK toolkit is not deprecated and
there is no schedule for its removal.
** The graphic object property "PickableParts" has been implemented
which controls whether an object can accept mouse clicks.
** The graphic object property "Interruptible" has been fully
implemented which controls whether a running callback function can
be interrupted by another callback function.
** The graphic object property "HitTest" has been updated to be fully
compatible with Matlab.
** Text objects now implement the properties "BackgroundColor",
"EdgeColor", "LineStyle", "LineWidth", and "Margin".
** An initial implementation of alpha transparency has been made for
patch and surface objects. Printing to svg and pdf is supported.
** ishandle now returns true for both graphics handle objects and
Java objects. The latter change was made for Matlab compatibility.
Use ishghandle or isgraphics if it is important not to include Java
objects.
** The pkg command now accepts a URL as an argument, allowing a valid
Octave package to be installed from any remote host with one command,
for example
pkg install https://example.org/download/example-package.tar.gz
** The following statistical functions have been moved from core
Octave to the statistics package available from Octave Forge.

allow overriding MKOCTFILE_* and use it to provide a full path gfortran,
so the invocation doesn't fail because gfortran isn't normally in PATH
Force the use of bsdtar. unpacking yielding random PaxHeaders.1234 triggers
an octave package sanity check making the build of the 'signal' package
fail with a cryptic error with no further diagnostics.

Fixes build with PKGSRC_FORTRAN=gfortran (6.4) on netbsd. resulting
binary works fine. I suspect the issue is that the wrong gcc (one without
fortran support) is invoked.

octave is using gnulib for portability, but has an additional wrapper
around it. unfortunately that means that this type signature is no longer
portable. netbsd doesn't have struct tm_zone, others do.
I failed to use gnulib to provide struct tm_zone, using an OS-specific macro
as an ugly hack.

Since arpack installs a dynamic library, its BUILDLINK_DEPMETHOD

pkgsrc changes: removed all patches to do with qt5 support, upstream
code does it now. blindly moved some patches that were replacing
INSTALL_PROGRAM to INSTALL_LIB as the build changed. added patch
replacing struct tm_zone with timezone_t to accommodate for missing
type in NetBSD - same as libgnu does.

Summary of important user-visible changes for version 4.2:
---------------------------------------------------------
** The parser has been extended to accept, but ignore, underscore
characters in numbers. This facilitates writing more legible code
by using '_' as a thousands separator or to group nibbles into bytes
in hex constants.
Examples: 1_000_000 == 1e6 or 0xDE_AD_BE_EF
** The parser has been extended to understand binary numbers which
begin with the prefix '0b' or '0B'. The value returned is Octave's
default numeric class of double, not at unsigned integer class.
Therefore numbers greater than flintmax, i.e., 2^53, will lose some
precision.
Examples: 0b101 == 5 or 0B1100_0001 == 0xC1
** gnuplot 4.4 is now the minimum version supported by Octave.
** The default set of colors used to plot lines has been updated to be
compatible with Matlab's new default color scheme. The line plot
color scheme can be set with the axes property "ColorOrder".
** The default colormap is now set to "viridis" which is also the
default colormap in matplotlib. This new colormap fixes some of the
main issues with the old default colormap "jet" such as its bad
"luminance profile" and is also more similar to Matlab's new default
colormap "parula".
** The colormap function no longer supports the input argument "list"
to show built-in colormaps. Use "help colormap" to find the
built-in colormaps.
** The graphics command "hold on" now ensures that each new plot added
to an existing plot has a different color or linestyle according to
the "ColorOrder" and/or "LineStyleOrder" properties. This is
equivalent to the old command "hold all" and was made for Matlab
compatibility. Existing code *may* produce differently colored
plots if it did not specify the color for a plot and relied on each
new plot having the default first color in the "ColorOrder"
property.
** When starting, Octave now looks in the function path for a file
startup.m and executes any commands found there. This change was
made to accommodate Matlab users. Octave has it's own configuration
system based on the file .octaverc which is preferred.
** Octal ('\NNN') and hex ('\xNN') escape sequences in single quoted
strings are now interpreted by the function do_string_escapes().
The *printf family of functions now supports octal and hex escape
sequences in single-quoted strings for Matlab compatibility.
** Special octal and hex escape sequences for the pattern and
replacement strings in regular expressions are now interpreted for
Matlab compatibility.
octal: '\oNNN' or '\o{NNN}'
hex : '\xNN' or '\x{NN}'
** Unknown escape sequences in the replacement string for regexprep are
now substituted with their unescaped version and no warning is
emitted. This change was made for Matlab compatibility.
Example: regexprep ('a', 'a', 'x\yz')
=> 'xyz'
** mkfifo now interprets the MODE argument as an octal, not decimal,
integer. This is consistent with the equivalent shell command.
** linspace now returns an empty matrix if the number of requested
points is 0 or a negative number. This change was made to be
compatible with Matlab releases newer than 2011. In addition,
Octave no longer supports matrix inputs for A or B.
** The cov function now returns the complex conjugate of the result
from previous versions of Octave. This change was made for
compatibility with Matlab.
** condest now works with a normest1 compatible syntax.
** The griddata function no longer plots the interpolated mesh if no
output argument is requested, instead the vector or array of
interpolated values is always returned for Matlab compatibility.
** The new function "light" and the corresponding graphics object
provide light and shadow effects for patch and surface objects.
** The surfnorm function now returns unnormalized (magnitude != 1)
normal vectors for compatibility with Matlab.
** The normal vectors returned from isonormals have been reversed to
point towards smaller values for compatibility with Matlab.
** The quadl function now uses an absolute, rather than relative,
tolerance for Matlab compatibility. The default tolerance is 1e-6
which may result in lower precision results than previous versions
of Octave which used eps as the relative tolerance. The quadl
function has also been extended to return a second output with the
total number of function evaluations.
** The textscan function is now built-in and is much faster and much
more Matlab-compatible than the previous m-file version.
** Dialog boxes--errordlg, helpdlg, inputdlg, listdlg, msgbox,
questdlg, and warndlg--now exclusively use Qt for rendering.
Java based versions have been removed.
** The axes properties "TitleFontSizeMultiplier" and "TitleFontWeight"
are now implemented which control the default appearance of text
created with title().
The axes property "LabelFontSizeMultiplier" is now implemented
which controls the default appearance of text created with
xlabel(), ylabel(), or zlabel().
** The graphics property "box" for axes now defaults to "off".
To obtain equivalent plots to previous versions of Octave use
set (0, "DefaultAxesBox", "on");
in your .octaverc file.
** The graphics property "boxstyle" has been implemented. The default
is "back" which draws only the back planes in a 3-D view. If the
option is "full" then all planes are drawn.
** The graphics property "erasemode" has been hidden, and will
eventually be removed. This property has also been removed
from Matlab, and was never implemented in Octave.
** The graphics property "graphicssmoothing" for figures now controls
whether anti-aliasing will be used for lines. The default is "on".
** The value "zero" for the axes properties "xaxislocation" and
"yaxislocation" has been deprecated and will be removed from
Octave 4.6. Use "origin" instead.
** The publish function allows easy publication of Octave script files
in HTML or other formats, including figures and output created by
this script. It comes with its counterpart grabcode, which lets one
literally grab the HTML published code from a remote website, for
example.
** The value of the MEX variable TrapFlag now defaults to 0, which will
cause Octave to abort execution of a MEX file and return to the
prompt if an error is encountered in mexCallMATLAB.
** The MEX API now includes the function mexCallMATLABWithTrap. This
function will not abort if an error occurs during mexCallMATLAB, but
instead will return execution to the MEX function for error
handling.
** The MEX API functions for input validation that begin with "mxIs"
(e.g., mxIsDouble, mxIsEmpty, etc.) now return type bool rather than
type int.
** The functions mxAssert and mxAssertS for checking assertions have
been added. In order to avoid a performance penalty they are only
compiled in to debug versions of a MEX file, i.e., that are produced
when the '-g' option is given to mex or mkoctfile.
** Other new MEX API functions include mexEvalStringWithTrap,
mxIsScalar, mxCreateUninitNumericArray, mxCreateUninitNumericMatrix.
** Other new functions added in 4.2:
audioformats
camlight
condeig
deg2rad
dialog
evalc
hash
im2double
isocaps
lighting
localfunctions
material
normest1
ode23
ode45

** Deprecated functions.
The following functions have been deprecated in Octave 4.2 and will
be removed from Octave 4.6 (or whatever version is the second major
release after 4.2):
Function | Replacement
---------------------|------------------
bitmax | flintmax
mahalanobis | mahal in Octave-Forge statistics pkg
md5sum | hash
octve_config_info | __octave_config_info__
onenormest | normest1
sleep | pause
usleep | pause
wavread | audioread
wavwrite | audiowrite
** The following functions were deprecated in Octave 3.8 and have been
removed from Octave 4.2.
default_save_options java_new
gen_doc_cache java_unsigned_conversion
interp1q javafields
isequalwithequalnans javamethods
java_convert_matrix re_read_readline_init_file
java_debug read_readline_init_file
java_invoke saving_history
** The global error_state variable in Octave's C++ API has been
deprecated and will be removed in a future version. Now the error
and print_usage functions throw an exception
(octave::execution_exception) after displaying the error message.
This makes the error and print_usage functions in C++ work more like
the corresponding functions in the scripting language.
** The default error handlers in liboctave have been updated to use
exceptions. After displaying an error message they no longer return
control to the calling program. The error handler function can be
customized through the global variables
"current_liboctave_error_handler" and
"current_liboctave_error_with_id_handler". If a programmer has
installed their own custom error handling routines when directly
linking with liboctave then these must be updated to throw an
exception and not return to the calling program.
** The system for common errors and warnings has been renamed from
gripe_XXX to either err_XXX if error is called or warn_XXX if
warning is called. The gripe_XXX functions are deprecated and will
be removed in version 4.6.
** New configure option, --enable-address-sanitizer-flags, to build
Octave with memory allocator checks (similar to those in valgrind)
built in.
