+   The FFmpeg Project proudly presents FFmpeg 2.5 "Bohr", just 2.5 months
+   after the release of 2.4. 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).
