+<h1>Libvorbisenc API changes 1.0  through 1.1</h1>
+
+This document describes API additions to libvorbisenc between release
+1.0 and 1.1.
+
+<h2>1.0.1</h2> 
+
+The programming API and binary application ABI are unchanged and fully
+forward/backward compatible between release 1.0 and 1.0.1.  Libvorbis,
+libvorbisenc and libvorbisfile must match versions amongst themselves,
+however.
+
+<h2>1.1</h2>
+
+The binary ABI from release 1.0.1 to 1.1 is backward compatible;
+applications linked against libvorbis/libvorbisenc 1.0 and 1.0.1 will
+continue to function correctly when upgrading the libvorbis and
+libvorbisenc dynamic libraries without re-linking. <p>
+
+Release 1.1 adds several possible requests to the libvorbisenc <a
+href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> call in order to
+reflect the shift to <a href="overview.html#BBR">bit-reservoir style
+bitrate management</a>. In addition, several <a
+href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> requests are
+deprecated (but functional) as they are redered semantically obsolete
+by the <a href="overview.html#BBR">new bitrate management</a>.<p>
+
+<h3>Deprecated in 1.1</h3>
+
+These calls are still available to older codebases to preserve
+compatability; the fields of the <a
+href="ovectl_ratemanage_arg.html">ovectl_ratemanage_arg</a> argument
+are mapped as closely as possible to the fields of the new <a
+href="ovectl_ratemanage2_arg.html">ovectl_ratemanage2_arg</a>
+structure.
+
+<dl>
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE_GET">OV_ECTL_RATEMANAGE_GET</a>:<dd> Use <a
+href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_GET">OV_ECTL_RATEMANAGE2_GET</a>
+instead.  
+
+
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE_SET">OV_ECTL_RATEMANAGE_SET</a>:<dd> Use <a
+href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET</a>
+instead.
+
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE_AVG">OV_ECTL_RATEMANAGE_AVG</a>:<dd> Use <a
+href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET</a>
+instead.
+
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE_HARD">OV_ECTL_RATEMANAGE_HARD</a>:<dd> Use <a
+href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET</a>
+instead.
+</dl>
+
+<h3>Newly added in 1.1</h3>
+
+The following calls are added in 1.1 to semantically reflect movement
+to a <a href="overview.html#BBR">bit-reservoir-based bitrate
+management</a> scheme by introducing the <a
+href="ovectl_ratemanage2_arg.html">ovectl_ratemanage2_arg</a>
+structure in order to better represent the abilities of the bitrate
+manager.<p>
+
+<dl>
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_GET">OV_ECTL_RATEMANAGE2_GET</a><dd>
+
+Used to query the current state of bitrate management setup.
+
+<dt><a href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET</a><dd>
+
+Used to set or alter bitrate management settings.
