+ └────────────────────────────────────────┘
- The FFmpeg Project proudly presents FFmpeg <next> "FIXME", ...
+ The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", just 2 months
+ after the release of 2.3. Since this wasn't a long time ago, the Changelog
+ is a bit short this time.
+
+ The most important thing in this release is the major version bump of the
+ libraries. This means that this release is neither ABI-compatible nor
+ fully API-compatible. But on the other hand it is aligned with the Libav
+ 11 release series, and will as a result probably end up being maintained for
+ a long time.
+
+ As usual, if you have any question on this release or any FFmpeg related
+ topic, feel free to join us on the #ffmpeg IRC channel (on
+ irc.freenode.net).
