+ </ul>
+ <p>
+ This release had been overdue for at least half a year, but due to
constant activity in the repository,

recently, before some of the large
+ changes scheduled for 7.0 were merged.
+ </p>
+ <p>
+ 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).</br>
+ This also led to a reduction in the the size of the compiled binary, which
can be noticeable in small builds.</br>
+ There was a very large reduction in the total amount of allocations being
done on each frame throughout video decoders,
+ reducing overhead.</br>
+ RISC-V optimizations for many parts of our DSP code have been merged, with
mainly the large decoders being left.</br>
+ There was an effort to improve the correctness of timestamps and frame
durations of each packet, increasing the
+ accurracy of variable frame rate video.
+ </p>
+ <p>
+ 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.
+ </p>
+ <p>
+ We strongly recommend users, distributors, and system integrators to
upgrade unless they use current git master.
+ </p>
I hope I didn't forget to mention anything else that was notable.
Attached.
