Changelog:
GEGL-0.4.16
Not available
GEGL-0.4.15
Build
Added gitlab continuous integration.
Core
Platform specific build fixes for both win32 and OSX.
Avoid in-place processing for cached nodes.
Indentation consitency improvements.
Permit more detailed specifying/overriding of OpenCL device through the
GEGL_USE_OPENCL environment variable.
New call gegl_update_anim_time for applying the animation curves of
properties.
Buffer
Swapped behavior of cubic interpolation from cubic to mithcell
coefficients, leading to crisper results in all uses of the cubic
sampler.
Permit tiles to be unreffed after GEGL shut-down without crash, which
is likely when using bindings to dynamic languages.
Use malloc_trim when compiled with glibc to possibly decrease the
resident size of progress when buffers are destroyed.
Improved deadlock prevention in gegl_buffer_copy() when using copy on
write.
Operations
Use indirect buffer inputs on main thread during multi-processed
processing for point-filters/composers and tranform base classes.
Smaller required/invalided ROI for map-absolute/relative when using
nearest neighbor.
tiff-save and jpg-save fixed dimensions when buffer saved has non-zero
origin
Added missing descriptions of properties for cubism, mosaic,
tile-paper, color, mantiuk06 and vignette operations.
ff-load fix some of the deprecation warnings.
ff-save avoid crashing if audio or video codec fails to initialize.
cache, parent class changed - it is no longer a point operations, also
speed up processing and permit copy on write handling of tiles.
opacity and invert - crash for 8bpc buffers, reimplemented logic for
(non-)associated alpha OpenCL kernel selection.
Tools
Drop direct dependency on exiv2 - we now only transiently depend on it
through the gexiv2 abstraction.
commandline tool/gui
Store per image editing chains in .gegl folder instead of sidecars.
Set window title, permit interaction with opened .lui documents, fixed
playback of audio for opened videos - it now works; if the video is
decoding, scaling and display is fast enough to leave spare cycles.

without dropping audio frames.
Support for custom collection order and per-file key-value metadata.

UI
The existing microraptor-gui (immediate mode touch UI+CSS with cairo)
image viewer that can be built as part of the gegl binary has been
revisted, a graph/property editor has been added, and migration/
extension to lua has begun for parts of the code.
many parts of the UI is of exploratory proof of concept/alpha
Warning quality but released since it is part of the GEGL repository
and useful development tools both for creating and testing new
GEGL operations as well as GEGL itself.
Some screenshots showing some the process towards the state and
capabilties of the UI in this release can be seen at https://

To build with this UI the following dependencies also need to be
satisifed, for now this is not intended to be packaged by distributions
yet.
libluajit-dev
lua-lgi (debian package name) upstream:
mmm https://github.com/hodefoting/mmm
mrg https://github.com/hodefoting/mrg
Features: folder view resolution independent UI touch oriented
navigation GIF / video playback PDF pagination goats that expose
performance and capabilty issues in GEGL efficient (though not
sandboxed) thumbnailing embedded simple commandline graph editor
zoomable automatic, consistent graph layout autogenerated

This release depends on the new features of babl-0.1.62 which has the
following change summary for the last release:
Continuous integration with gitlab. Initial CMYK spaces with lcms2
based ICC support, much room for optimization. Improved custom space
support for palette formats. scRGB space, works like sRGB but always
with linear TRCs. Model introspection API permitting low overhead
checks whether a format/model is RGB, CMYK type of alpha and similar.

framework.
GEGL provides infrastructure to do demand based cached non destructive
image editing on larger than RAM buffers. Through babl it provides
support for a wide range of color models and pixel storage formats for
input and output.
