MLT Release Notes
-----------------
+Version 0.5.6
+
+The recommended version of FFmpeg for use with this release is 0.6.
+This is a maintenance release to address some bugs that appeared
+this far in the 0.5.x series. Beyond that it a few enhancements:
+
+* Added interpolation to the affine transition and filter.
+* Added multi-track audio encoding to avformat consumer.
+* Added interlaced field rendering to kdenlivetitle producer.
+
+
+Version 0.5.4
+
+The recommended version of FFmpeg for use with this release is SVN r21322.
+This is another maintenance release to address some bugs that appeared
+this far in the 0.5.x series. Beyond that it adds two things that only
+very specific users will see:
+
+* Added C# (ECMA CLR) binding (not enabled by default).
+* Linsys SDI consumer now configures itself from MLT profile.
+
+
+Version 0.5.2
+
+The recommended version of FFmpeg for use with this release is SVN r21322.
+This is a minor maintenance release, but it is interesting because it now
+enables usage of libswscale as the default choice for image scaling,
+image format conversion, and color space conversion. That gives better
+quality and performance. In addition, there are some improvements in the
+sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
+things:
+
+* Fixed mlt++/MltFilteredProducer
+* Fixed playing to the end in Kdenlive (mantis bug 1207)
