  │ RELEASE NOTES for FFmpeg 2.4 "Fresnel" │
  └────────────────────────────────────────┘
 
-   The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", ...
-   FFmpeg 2.4 is mostly API-, but not ABI-compatible with the previous major release.
-   This means that the code using our libraries needs to be rebuilt, but only minimal
-   source changes should be required, as described in the section 'API Information'.
+   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).
