4 Version 0.8.0 - June 1, 2012
6 The minor version is increased due to the addition of time properties!
7 The soname version increased in the process because some mlt_property
8 functions changed; however, very few if any apps actually directly use
9 mlt_property preferring to use mlt_properties instead. In addition:
11 * improve seek speed on AVCHD when using FFmpeg v0.9.1+ (NOT Libav!)
12 * composite and dissolve speed improvements on x86-64
13 * improve performance of caching in image producers

95 version at this time. With that said, there were changes to accomodate the
96 API changes with some moderate testing of the 0.6, 0.7, and 0.8 series
97 releases of both FFmpeg and Libav.
100 Version 0.7.2 - May 1, 2011
102 This is a minor release to fix a few things between the 0.7.0 release
103 and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to
104 upgrade to this version of Mlt. Beyond that there are some exciting
105 additions to the Blackmagic Design DeckLink plugin!

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

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