72 Version 0.8.0 - June 1, 2012
74 The minor version is increased due to the addition of time properties!
75 The soname version increased in the process because some mlt_property
76 functions changed; however, very few if any apps actually directly use

165 releases of both FFmpeg and Libav.
168 Version 0.7.2 - May 1, 2011
170 This is a minor release to fix a few things between the 0.7.0 release
171 and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to
172 upgrade to this version of Mlt. Beyond that there are some exciting
173 additions to the Blackmagic Design DeckLink plugin!

279 This is a quick followup to the 0.5.8 release to address an issue I want to
280 address immediately. I noticed an extra unconditional colorspace conversion
281 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
282 have enabled the avcolor_space filter on OS X since it works now.
285 Version 0.5.8 - September 12, 2010
287 The recommended version of FFmpeg for use with this release is 0.6.

326 This is a minor maintenance release, but it is interesting because it now
327 enables usage of libswscale as the default choice for image scaling,
328 image format conversion, and color space conversion. That gives better
329 quality and performance. In addition, there are some improvements in the
330 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
