The major announcement is the introduction of support for libavfilter! This is still a work-in-progress. It is limited to FFmpeg 2.3 and up, and there are a number of filters that are black-listed because they are known to not integrate with MLT, which is not a full libav* environment or simple wrapper for it. There are likey avfilters that are not yet black-listed but might not work because they have not been completely tested. Also, they do not support MLT's keyframable property animation nor its frame-threaded parallelism due to architectural or integration limitations. However, some avfilters are slice-threaded (internal parallelism), and that works. Finally, libavfilter filtergraph syntax is not supported either.
All of the supported libavfilters are exposed as MLT filters beginning with the prefix "avfilter." All of the avfilter parameters are exposed as MLT properties with the "av." prefix to prevent clashes with MLT properties. You can run:
melt -query filters to see the new avfilters, and
melt -query filter=avfilter.rotate, for example, to view generated documentation for an individual filter.

This is a bugfix and minor enhancement release. Note that our release versioning scheme has changed. We were approaching 1.0 but decided to synchronize release version with the C library ABI version, which is currently at v6. Here are some of the notable changes and enhancements:
