| 2 | │ RELEASE NOTES for FFmpeg 2.4 "Fresnel" │ | |
| 3 | └────────────────────────────────────────┘ | |
| 4 | ||
| 5 | The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", just 2 months | |
| 6 | after the release of 2.3. Since this wasn't a long time ago, the Changelog | |
| 7 | is a bit short this time. | |
| 8 | ||
| 9 | The most important thing in this release is the major version bump of the | |
| 10 | libraries. This means that this release is neither ABI-compatible nor | |
| 11 | fully API-compatible. But on the other hand it is aligned with the Libav | |
| 12 | 11 release series, and will as a result probably end up being maintained for | |
| 13 | a long time. | |
| 14 | ||
| 15 | As usual, if you have any question on this release or any FFmpeg related | |
| 16 | topic, feel free to join us on the #ffmpeg IRC channel (on | |
| 17 | irc.freenode.net). | |
