Release Notes
=============
-* 0.8 "Love" June, 2011
-* 0.7 "Peace" June, 2011 (identical to 0.8 but using 0.6 ABI/API)
+* 0.10 "Freedom" January, 2012
General notes
-------------
+This release is binary compatible with 0.8 and 0.9.
-This release enables frame-based multithreaded decoding for a number of codecs,
-including theora, huffyuv, VP8, H.263, mpeg4 and H.264. Additionally, there has
-been a major cleanup of
-both internal and external APIs. For this reason, the major versions of all
-libraries except libpostproc have been bumped. This means that 0.8 can be installed
-side-by-side with previous releases, on the other hand applications need to be
-recompiled to use 0.8.
-
-Other important changes are more than 200 bugfixes, known regressions were fixed
-w.r.t 0.5 and 0.6, additions of decoders including, but not limited to,
-AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
-and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
-HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
-
-See the Changelog file for a list of significant changes.
+See the Changelog file for a list of significant changes. Note, there
+are many more new features and bugfixes than whats listed there.
Bugreports against FFmpeg git master or the most recent FFmpeg release are
accepted. If you are experiencing issues with any formally released version of
make your report against the development code following the usual bug reporting
guidelines.
-Note, if you have difficulty building for mingw, try --disable-outdev=sdl
-
API changes
-----------
-Please see git log of the public headers or the file doc/APIchanges for
-programmer-centric information. Note that some long-time deprecated APIs have
-been removed. Also, a number of additional APIs have been deprecated and might
-be removed in the next release.
+A number of additional APIs have been introduced and some existing
+functions have been deprecated and are scheduled for removal in the next
+release. Significant API changes include:
+
+* new audio decoding API which decodes from an AVPacket to an AVFrame and
+is able to use AVCodecContext.get_buffer() in the similar way as video decoding.
+
+* new audio encoding API which encodes from an AVFrame to an AVPacket, thus
+allowing it to properly output timing information and side data.
+
+Please see the git history and the file doc/APIchanges for details.

+Libavcodec and libavformat built as shared libraries now hide non-public
+symbols. This will break applications using those symbols. Possible solutions
+are, in order of preference:
+1) Try finding a way of accomplishing the same with public API.
+2) If there is no corresponding public API, but you think there should be,
+post a request on the developer mailing list or IRC channel.
+3) Finally if your program needs access to FFmpeg / libavcodec / libavformat
+internals for some special reason then the best solution is to link statically.
