This release had been overdue for at least half a year, but due to constant activity in the repository, had to be delayed, and we were finally able to branch off the release recently, before some of the large changes scheduled for 7.0 were merged.

Internally, we have had a number of changes too. The FFT, MDCT, DCT and DST implementation used for codecs and filters has been fully replaced with the faster libavutil/tx (full article about it coming soon).
This also led to a reduction in the the size of the compiled binary, which can be noticeable in small builds.
There was a very large reduction in the total amount of allocations being done on each frame throughout video decoders, reducing overhead.
RISC-V optimizations for many parts of our DSP code have been merged, with mainly the large decoders being left.
There was an effort to improve the correctness of timestamps and frame durations of each packet, increasing the accurracy of variable frame rate video.

Next major release will be version 7.0, scheduled to be released in February. We will attempt to better stick to the new release schedule we announced at the start of this year.

We strongly recommend users, distributors, and system integrators to upgrade unless they use current git master.
