XZ Utils (XZ archiver)

XZ Utils Release Notes ====================== 5.0.3 (2011-05-21) * liblzma fixes: - A memory leak was fixed. - lzma_stream_buffer_encode() no longer creates an empty .xz Block if encoding an empty buffer. Such an empty Block with LZMA2 data would trigger a bug in 5.0.1 and older (see the first bullet point in 5.0.2 notes). When releasing 5.0.2, I thought that no encoder creates this kind of files but I was wrong. - Validate function arguments better in a few functions. Most importantly, specifying an unsupported integrity check to lzma_stream_buffer_encode() no longer creates a corrupt .xz file. Probably no application tries to do that, so this shouldn't be a big problem in practice. - Document that lzma_block_buffer_encode(), lzma_easy_buffer_encode(), lzma_stream_encoder(), and lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. - The return values of the _memusage() functions are now documented better. * Fix command name detection in xzgrep. xzegrep and xzfgrep now correctly use egrep and fgrep instead of grep. * French translation was added.
