Major changes for 1.4 are:
Epoxy can now build with MSVC versions prior to 2013; we still recommend using a recent, C99-compatible compiler, like MSVC 2015 [Chun-wei Fan]
When used under X11, Epoxy now attempts to handle the cases where the GLX extension is not built or not available [Yaron Cohen-Tal]
GLX can now be enabled and disabled at configuration time; this allows building Epoxy with GLX on macOS, and allows building Epoxy without GLX on embedded platforms
Epoxy now exposes API that lets dependent projects safely check if platform API like GLX and EGL is available at run time
EGL support has been improved on Windows, and made more resilient on other platforms [Yaron Cohen-Tal, Adam Jackson]
Epoxy supports building with the Meson build system, which has Ninja, Visual Studio, and XCode backends
Epoxy can generate its API reference using Doxygen (currently only available on Meson builds)
The GL registry has been updated with the latest version of the API references provided by Khronos; Epoxy now supports the API introduced by OpenGL 4.5
Some critical bugs in the processing of BMP files were fixed. These
bugs allowed the program to be crashed, or potentially to be abused
in other ways, by feeding it specially crafted BMP files. Thanks to
Tomasz Buchert and Agostino Sarubbo for reporting these bugs.
Portability was improved for C99 and for MSVC++. Thanks to Peter
Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting
portability issues.
Core:
- Avoid D-Bus error message when built without D-Bus support
- fix OS X min required conditional in gimpimagewindow.c
- Saving to existing .xcf.bz and .xcf.gz files didn't truncate them
and could lead to unnecessarily large files
- Text layer created by gimp-text-fontname doesn't respect border
when resized
- avoid seeking when saving XCF files to prevent corruption with
file network shares (fixed since 2014, but not mentioned in NEWS yet)
GUI:
- Flow on Paint Dynamics editor dialog: the 'y' axis is indicating
'Rate' instead 'Flow'
- Vertical ruler shows artifacts if the status bar isn't showing
- Tablet stylus misbehaves when crossing the edge of a dock in
multi-window-mode
- Disable the new "automatic window tabbing" feature introduced on macOS
Sierra
- Improve the visiblity of slider handles with dark themes
- Make it harder to switch to renaming if selecting already selected
items in resource lists
Tools:
- make toggling to color picker mode of paint tools more robust
Libgimp:
- call gimp_file_entry_set_filename() with filename encoding
Windows Installer:
- Reduce the memory requirement when running the installer (has
already been shipped in a 2.8.18 installer-only update)
- Ship an updated libcairo to fix GTK+ UI rendering problems, like
missing palette border/bevel and shadowa under tab labels
macOS DMG:
- Ship the Tango icon theme with the DMG for a complete set of icons
- fix the way mime data is copied into the bundle
- no longer copy Pango modules into the bundle
- prevent a crash caused by drag&drop on OSX by patching the included
GTK+
- ship a patch for gettext to make sure the preferred UI language
will be used
Plug-ins:
- Prevent the Python console from closing by the Escape key
- Help browser does not launch on OS X
- Filter 'Edge Detect/Difference of Gaussians' returns empty image
- only use -xobjective-c for compile commands
- mkgen.pl: fix calls to write_file() routine to write to current
directory
- When printing, the images are composed onto a white background to
prevent printing a black box instead of a transaprent image
- Fix color visison deficiency display filters to apply gamma
correction directly
2017-02-04 7.0.4-7 Cristy <quetzlzacatenango@image...>
* Release ImageMagick version 7.0.4-7, GIT revision 19513:5783e57:20170204.
2017-01-28 7.0.4-7 Cristy <quetzlzacatenango@image...>
* Sanitize comments that include braces for the MIFF image format (reference
https://github.com/ImageMagick/ImageMagick/issues/368).
2017-01-27 7.0.4-7 Glenn Randers-Pehrson <glennrp@image...>
* coders/png.c: Added support for a proposed new PNG chunk
(zxIf, read-only) that is currently being discussed on the
png-mng-misc at lists.sourceforge.net mailing list. Enable
exIf and zxIf with CPPFLAGS="-DexIf_SUPPORTED -DxzIf_SUPPORTED".
If exIf is enabled, only the uncompressed exIF chunk will be
written and the hex-encoded zTXt chunk containing the raw Exif
profile won't be written.
2017-01-27 7.0.4-6 Cristy <quetzlzacatenango@image...>
* Release ImageMagick version 7.0.4-6, GIT revision 19442:4747de9:20170127.
2017-01-27 7.0.4-6 Cristy <quetzlzacatenango@image...>
* Uninitialized data in MAT image format (reference
https://github.com/ImageMagick/ImageMagick/issues/362).
* Properly auto-fit caption (reference
https://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=30887).
* Correction to composite Over operator (reference
https://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=31282).
* Respect gravity option (reference
https://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=31284).
2017-01-22 7.0.4-6 Glenn Randers-Pehrson <glennrp@image...>
* Renamed read_vpag_chunk_callback() function to png_user_chunk_callback()
in coders/png.c
* Implemented a private PNG caNv (canvas) chunk for remembering the
original dimensions and offsets when an image is cropped. Previously
we used the oFFs and vpAg chunks for this purpose, but this had potential
conflicts with other applications that also use the oFFs chunk.
* coders/png.c: Added support for a proposed new PNG chunk (exIf
read-write, eXIf read-only) that is currently being discussed on the
png-mng-misc at lists.sourceforge.net mailing list.
2017-01-22 7.0.4-6 Dirk Lemstra <dirk@lem.....org>
* Replaced CoderSeekableStreamFlag with CoderDecoderSeekableStreamFlag and
CoderEncoderSeekableStreamFlag.
