10-bit support in spp, but maybe it's more important to mention the addition
of colorlevels (yet another color handling filter), tblend (allowing you
to for example run a diff between successive frames of a video stream), or
eventually the dcshift audio filter.
the dcshift audio filter.
There is also two other important filters landing in libavfilter: palettegen
and paletteuse, submitted by the Stupeflix company. These filters will be
very useful in case you are looking for creating high quality GIF, a format
that still bravely fights annihilation in 2015.

There are many other new features, but let's follow-up on one big cleanup
achievement: the libmpcodecs (MPlayer filters) wrapper is finally dead. The
last remaining filters (softpulldown/repeatfields, eq*, and various
postprocessing filters) were ported by Arwa Arif (OPW student) and Paul B
Mahol.
Concerning API changes, not much things to mention. Though, the introduction
of devices inputs and outputs listing by Lukasz Marek is a notable addition
(try ffmpeg -sources or ffmpeg -sinks for an example of the usage). As
usual, see doc/APIchanges for more information.

Now let's talk about optimizations. Ronald S. Bultje made the VP9 decoder
usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
Athlons can play 1080p 30fps VP9 content now), so we now secretly hope for
Google and Mozilla to use ffvp9 instead of libvpx.
But VP9 is not the center of attention anymore, and HEVC/H.265 is also
getting many improvements, which includes optimizations, both in C and x86
ASM, mainly from James Almer, Christophe Gisquet and Pierre-Edouard Lepere.

Even though we had many x86 contributions, it is not the only architecture
getting some love, with Seppo Tomperi adding ARM NEON optimizations to the
