+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.
+
+
+Movit 1.0.2, March 16th, 2014
+
+ - Make a few tweaks to “make install”, to make distributions' lives easier.
+
+
+Movit 1.0.1, March 16th, 2014
+
+ - Fix so that shared libraries are built.
+

 Movit 1.0, March 16th, 2014
 
  - Initial release.
