Changes 5.0.0: * The memory usage limit is now disabled by default. * Added support for XZ_DEFAULTS environment variable. * The compression settings associated with the preset levels -0 ... -9 have been changed. --extreme was changed a little too. * If a preset level (-0 ... -9) is specified after a custom filter chain options have been used (e.g. --lzma2), the custom filter chain will be forgotten. Earlier the preset options were completely ignored after custom filter chain options had been seen. * xz will create sparse files when decompressing if the uncompressed data contains long sequences of binary zeros. * Support for "xz --list" was added. Combine with --verbose or --verbose --verbose (-vv) for detailed output. * I had hoped that liblzma API would have been stable after 4.999.9beta, but there have been a couple of changes in the advanced features, which don't affect most applications: - Index handling code was revised. If you were using the old API, you will get a compiler error (so it's easy to notice). - A subtle but important change was made to the Block handling API. lzma_block.version has to be initialized even for lzma_block_header_decode(). Code that doesn't do it will work for now, but might break in the future, which makes this API change easy to miss. * The major soname has been bumped to 5.0.0. liblzma API and ABI are now stable, so the need to recompile programs linking against liblzma shouldn't arise soon.
