 libx264.c backport
 ------------------
 
 This release includes a backport to the libx264 wrapper that allows FFmpeg to
 be compiled against newer versions of libx264 up to API version 85.

+licensing changes
+-----------------
+
+Previously both libswscale and our AC-3 decoder had GPLed parts. These have
+been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
+but the C code is fully functional. Optimizations for other architectures have
+been relicensed to LGPL.
+
+AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
+software OpenCORE libraries as an alternative to the non-free libamr libraries.
+
+We found out that libfaac contains non-free parts and is not LGPL as previously
+claimed. We have changed configure to reflect this. You now have to pass the
+--enable-nonfree option if you wish to compile with libfaac support enabled.
+
+Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
+well that they were only used in a test program and never compiled into any
+FFmpeg library.
