+Movit 1.4.0, November 5th, 2016
+
+ - Allow setting the intermediate format for chains, instead of hardcoding
+ it at 16-bit RGBA; advanced users can use this to e.g. ask for 8-bit
+ sRGB intermediates, reducing the amount of memory bandwidth needed
+ at the cost of reduced precision. Whether this is a good tradeoff or not
+ depends on the exact chain and your requirements.
+
+ - Fix an issue where a (cached) shader program could be used from multiple
+ threads at a time, causing the uniforms to contain unpredictable values.
+
+ - Make the error printed on check_error() slightly friendlier: Include the
+ enum if possible, and print it to stderr instead of stdout.
+
+
+Movit 1.3.2, February 23rd, 2016
+
+ - Fix an issue with initialization in certain locales. Patch from
+ Jean-Baptiste Mardelle.
+
+
+Movit 1.3.1, February 15th, 2016
+
+ - Fix an issue where certain effect chains (particularly involving
+ out-of-tree effects that return only a constant color) could cause
+ texture coordinates not to be set properly. (The new code probably
+ also has slightly lower OpenGL driver overhead.) Reported by
+ Christophe Thommeret.
+
+
+Movit 1.3.0, January 31st, 2016
+
+ - Movit now requires GLSL 1.30 (so a driver from 2008 or later);
+ before, it claimed to support 1.10, but actually used 1.30 features.
+ Note that some OpenGL drivers, in particular on OS X, only supports
+ GLSL 1.30 (actually, 1.50) if you have an OpenGL core context.
+
+ - Add a deinterlacer, based on YADIF.
+
+ - Allow parallel output to RGBA and Y'CbCr textures at the same time.
+
+ - Make FlatInput and YCbCrInput support taking in external OpenGL
+ textures. Also allow them to change width/height after instantiation.
+
+ - Various compatibility and performance fixes. In particular,
+ fp16 conversion on older (non-Haswell) CPUs is much faster, due to
+ new conversion code by Fabian Giesen.
+
+
+Movit 1.2.0, September 24th, 2015
+
+ - Movit now ships a version.h with a #define MOVIT_VERSION that
+ increases on every API change, including in git. (The number
+ itself carries no semantic meaning beyond this.) Movit 1.2.0
+ is not API or ABI compatible with 1.1.x, so there has been a
+ soname bump to libmovit.so.3.
+
+ - More flexible Y'CbCr input; in particular, a special input
+ for 4:2:2 interleaved data (UYVY), and support for semi-planar
+ input (Cb and Cr in the same texture, like in NV12). Note that
+ you should now also set the new “num_levels” member of
+ YCbYCbCrFormat to 256 (signifying 8-bit input), although
+ it is not used yet; this is a stepping stone towards supporting
+ 10- and 12-bit Y'CbCr.
+
+ - Basic support for Y'CbCr _output_. Currently only 8-bit,
+ and only 4:4:4 (ie., you'll need to subsample yourself
+ afterwards). It is possible to split the output into multiple
+ textures, though, if you want a luma/chroma split (NV12-like)
+ or full planar.
+
+ - Support top-left origin for output. This is only really useful
+ if you are rendering directly into some memory area with top-left
+ origin; most users will get the expected behavior by using
+ bottom-left as before.
+
+ - Rework uniform handling for less OpenGL overhead. Note that
+ this means your effects now need to register uniforms in the
+ C++ code instead of declaring them in the .frag file.
+
+ - Make the PaddingEffect border subpixel-aware, and also support
+ an arbitrary (subpixel) border offset. This means that you can
+ compose PaddingEffect with an integral left/top offset
+ (use the new IntegralPaddingEffect for potentially more speed)
+ and ResampleEffect with a subpixel left/top offset (and zoom to
+ compensate) to get Lanczos interpolation for the pixels and a
+ simple bilinear interpolation for the border itself.
+
+ - Fix a bug that could cause very bad filter weights in
+ ResampleEffect.
+
+ - Various performance improvements, in particular with regards to
+ CPU usage in ResampleEffect.
+
+
+Movit 1.1.3, March 29th, 2015
+
+ - Fix accuracy issues in ResampleEffect, particularly when
+ zooming. Note that this might cost a few percent performance.
+ Reported by Christophe Thommeret.
+
+ - Make the number of BlurEffect taps configurable.
+ Based on patch by Christophe Thommeret.
+
+ - Multiple other bugfixes, some courtesy Dan Dennedy and
+ Christophe Thommeret. In particular, thread-safety fixes
+ related to locales and chain finalization.
+
+
+Movit 1.1.2, August 12th, 2014
+
+ - Performance bugfix: Fix texture freelist behavior so that it's
+ LRU instead of the exact opposite. Patch by Christophe Thommeret.
+
+ - Performance bugfix: Correct the number of blur taps read in the
+ blur filter (it was reading about twice as many as it should).
+ Also found by Christophe Thommeret.
+
+
+Movit 1.1.1, April 12th, 2014
+
+ - Fix an issue that could cause assertion failure in ResourcePool
+ when FBOs are reused, especially with NVIDIA's drivers.
+
+
+Movit 1.1, April 10th, 2014
+
+ - NOTE: Movit now uses libepoxy rather than GLEW. This is needed because
+ of core context and GLES3 support (see below). Movit 1.1 should be
+ generally API-compatible with 1.0.3 (with the exception of the next
+ point), but is not ABI-compatible, so there has been a soname bump
+ to libmovit.so.2.
+
+ - NOTE: The rules for using an EffectChain or ResourcePool in multiple
+ OpenGL contexts or threads have changed somewhat; see the comments in
+ resource_pool.h.
+
+ - Movit will now work in OpenGL core contexts, and on GLES 3.0 or newer.
+ (GLES2 devices are not supported.) This also holds for all unit tests,
+ provided that you use SDL2 and not SDL1 (because SDL2 is needed to set
+ up such contexts). Note that the included demo application still requires
+ a classic OpenGL context.
+
+ - ResampleEffect can now do sub-pixel translate and/or zoom.
+
+ - LumaMixEffect now has an “invert” flag, as a convenience to e.g. change
+ a left-to-right wipe into a right-to-left one.
+
+ - Significant reduction in driver overhead, especially on NVIDIA drivers.
+
+ - Various smaller bugfixes and performance improvements.
+
+
Movit 1.0.3, March 16th, 2014
- Yet more build system tweaks mainly related to distribution packaging.
