+Movit 1.6.3, July 7th, 2019
+
+ - Various bugfixes.
+
+
+Movit 1.6.2, March 18th, 2018
+
+ - Various bugfixes.
+
+
+Movit 1.6.1, January 31st, 2018
+
+ - Loosen up some restrictions on strong one-to-one-effects. In particular,
+ this fixes a bug with MixEffect and compute shaders that hit some
+ Nageru setups.
+
+
+Movit 1.6.0, January 24th, 2018
+
+ - Support for effects that work as compute shaders. Compute shaders are
+ generally slower than fragment shaders for the same algorithm,
+ but allow some forms of communication between shader invocations
+ and have more flexible output, which can enable more efficient algorithms.
+ See effect.h for more details. Note that the fastest rendering API on
+ EffectChain is now to a texture if possible, not to an FBO. This will
+ only matter if the last effect is a compute shader.
+
+ - Movit now includes a compute shader implementation of DeinterlaceEffect,
+ which is automatically used instead of the fragment shader implementation
+ if your GPU and OpenGL driver supports it (in practice, this means on
+ all platforms except on macOS). The compute shader version is typically
+ 20–80% faster than the fragment shader version, depending on your GPU
+ and other factors.
+
+ A compute shader implementation of ResampleEffect was written but
+ ultimately failed to be faster, and so is not included.
+
+ - Support for microbenchmarks of effects through the Google microbenchmarking
+ framework (optional). Currently, DeinterlaceEffect and ResampleEffect has
+ benchmarks; enable them by running the unit test with --benchmark (also try
+ --benchmark --help).
+
+ - Effects can now explicitly request _not_ to have mipmaps, which means they
+ can do so without needing to request bounce and fiddling with the sampler
+ state. Note that this is an API change for effects.
+
+ - Movit now requires C++11, both to build and to #include the header files.
+ Support for SDL1 has been dropped; unit tests and the demo program now need
+ SDL2.
+
+ - Various smaller bugfixes and optimizations.
+
+
+Movit 1.5.3, August 10th, 2017
+
+ - Various bugfixes.
+
+
+Movit 1.5.2, July 5th, 2017
+
+ - The texture generation for ResampleEffect (when the size is changed)
+ now uses less CPU.
+
+ - Work around an NVIDIA driver threading bug by aggressively caching VAOs.
+
+
+Movit 1.5.1, May 29th, 2017
+
+ - Allow YCbCrInput to change input format after finalize.
+
+ - Some minor YCbCrInput bugfixes.
+
+
+Movit 1.5.0, March 21st, 2017
+
+ - Support interleaved Y'CbCr input (4:4:4 in a single texture).
+
+ - Support 10-bit and 12-bit Y'CbCr, both for input and output. For planar,
+ these are supported packed in 16-bit ints; for interleaved, 10:10:10:2 is
+ supported. (Efficient conversion to and from v210, ie. 10-bit 4:2:2,
+ is possible using compute shaders, but Movit does not include support
+ for them at the current point.) Note that this now means the num_levels
+ flag in YCbCrFormat actually matters, although 0 will be interpreted
+ as 256 (8-bit) for the benefit of older applications.
+
+ - Limited support for having multiple Y'CbCr outputs from a chain.
+
+ - Allow changing the Y'CbCr output coefficients runtime, ie., after finalize.
+
+ - Fix an issue where the last pass would have been rendered with the sRGB
+ flag set, which confused Qt applications running in certain NVIDIA
+ configurations.
+
+
+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
