After months of intensive development, we're finally coming to a
stopping point in our rewrite of the libtheora reference
implementation. All major features for the 1.1 are in, so it's down to
bug fixing now. Please try this first beta and give us feedback. Most
notable is that the encoder's rate control is much more configurable,
and more capable in each configuration than before. It now supports
two-pass, dynamic target adjustment, frame dropping, and other
oft-requested features.

For now the only documentation of the two-pass support is in
examples/png2theora.c and examples/encoder_example.c. We'd
particularly like to hear from framework and application integrators
about how well the API design works.

Note that if you've been following this rewrite under the "thusnelda"
codename branch in the source repository, it has now moved to trunk. A
normal svn checkout http://svn.xiph.org/trunk/theora will now get the
1.1 code.

Thanks to everyone who contributed to this release, and especially to
the Mozilla Foundation and Red Hat who supported this work.
