Changes since the last public release (1.6.30):
Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
bug report by Michael Felt).
Revised pngpriv.h to work around failure to compile arm/filter_neon.S
("typedef" directive is unrecognized by the assembler). The problem
was introduced in libpng-1.6.30beta01.
Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
Added instructions for disabling hardware optimizations in INSTALL.
Added "--enable-hardware-optimizations" configuration flag to enable
or disable all hardware optimizations with one flag.
Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
possible integer overflow (Bug report by John Bowler).
Quieted "declaration after statement" warnings in intel/filter_sse2.c.
Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
integers appear on both sides of a compare. Worked around the others by
forcing the strict-overflow setting in the relevant functions to a level
where they are not reported (John Bowler).
Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
the space.
Worked around some C-style casts from (void*) because g++ 5.4.0 objects
to them.
Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
overflow' check that is on by default with -Wall -Wextra.
Added eXIf chunk support.
Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
tags) to pngtest.png.
* Follow semver
* Avoid implicit relative import
* Use utf-8 instead of utf8 in headers
* Keep cairo library loaded until all relevant objects are freed
* Add cairo_quartz_* functions for MacOS
* Use the default ReadTheDocs theme
* Fix implicit casts
Generalized fix solidgauge squares algorithm
Fix secondary series ‘stroke_style’ property
Fix wrong label colors when there are more series than colors
Show y guides in horizontal chart
Fix nomenclature of Taiwan
Better None values handling in logarithmic charts
in Python. It is built on top of matplotlib and tightly integrated with the
PyData stack, including support for numpy and pandas data structures and
statistical routines from scipy and statsmodels.
Some of the features that seaborn offers are
* Several built-in themes that improve on the default matplotlib aesthetics
* Tools for choosing color palettes to make beautiful plots that reveal
patterns in your data
* Functions for visualizing univariate and bivariate distributions or for
comparing them between subsets of data
* Tools that fit and visualize linear regression models for different kinds
of independent and dependent variables
* Functions that visualize matrices of data and use clustering algorithms to
discover structure in those matrices
* A function to plot statistical timeseries data with flexible estimation and
representation of uncertainty around the estimate
* High-level abstractions for structuring grids of plots that let you easily
build complex visualizations

Test: Optimize CI speed
* Several fixes for working with HDR images (display in GUI, photometric optimizer, handling of under/over exposured pixels in merging code).
* Fixes handling of masks in cpfind when images needs remapping for cp finding.
* Sometimes unsaved changes were disregarded without asking the user (e.g. when loading a project via the recently used projects list). Unsaved changes should now always require user confirmation.
Besides the bug fixes some smaller improvements have been implemented.
* Optimizer tabs uses now checkboxes instead of bold underlined font for marking of variables to be optimized.
* Use wxWidgets help windows instead of default browser (Linux&Mac only, this provides table of content, index and full text search in help files).
* Added special assistant variant for single image projects.
* Display of final panorama dimensions on stitcher tab.
* Extended the user defined output sequences:
- The shipped user defined output sequences are exposed in the GUI as own sub-menu.
- Added some more user defined output sequences (layered TIFF, cube faces).
- Added new placeholder %sourceimage% to user defined output sequence.
Changes since the last public release (1.6.29):
Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
makefile.linux and makefile.solaris-x86 (Cosmin).
Revised documentation of png_get_error_ptr() in the libpng manual.
Silence clang -Wcomma and const drop warnings (Viktor Szakats).
Update Sourceforge URLs in documentation (https instead of http).
Document need to check for integer overflow when allocating a pixel
buffer for multiple rows in contrib/gregbook, contrib/pngminus,
example.c, and in the manual (suggested by Jaeseung Choi). This
is similar to the bug reported against pngquant in CVE-2016-5735.
Removed reference to the obsolete PNG_SAFE_LIMITS macro in the documentation.
Check for integer overflow in contrib/visupng and contrib/tools/genpng.
Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt.
Test CMAKE_HOST_WIN32 instead of WIN32 in CMakeLists.txt.
Fix some URL in documentation.

compression buffer (bug report by Brian Baird). This bug was
introduced in libpng-1.6.0.
Update copyright year in pnglibconf.h, make ltmain.sh executable.
Add a reference to the libpng.download site in README.
