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

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

240 Version 0.5.10 - September 13, 2010
242 This is a quick followup to the 0.5.8 release to address an issue I want to
243 address immediately. I noticed an extra unconditional colorspace conversion
244 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
245 have enabled the avcolor_space filter on OS X since it works now.
248 Version 0.5.8 - September 12, 2010
250 The recommended version of FFmpeg for use with this release is 0.6.
251 This is a maintenance release to address some bugs that appeared

288 The recommended version of FFmpeg for use with this release is SVN r21322.
289 This is a minor maintenance release, but it is interesting because it now
290 enables usage of libswscale as the default choice for image scaling,
291 image format conversion, and color space conversion. That gives better
292 quality and performance. In addition, there are some improvements in the
293 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
