30 Version 0.8.0 - June 1, 2012
32 The minor version is increased due to the addition of time properties!
33 The soname version increased in the process because some mlt_property

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

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

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