Release Notes: Be warned that the API and data format have been changed in ways that are not backwards compatible. A high speed librsync swig extension module was added. An MD4 extension module was added. The API was changed to be more like librsync/rdiff. distutils is now used to build releases for Linux and Windows.
Release Notes: This release includes support for xdelta style deltas (optimized deltas calculated directly from the sourcefile, not a signature), simplified and optimized code to take advantage of python buffer() copy-less string slicing, and command-line delta calculation now reads files incrementaly.
Release Notes: pysync.py was changed to use the new zlib-like API. A serious adler32 bug affecting rolling checksums was fixed. pysync-test.py was added for testing pysync.py.
