Release Notes: A massive code rewrite was done. Compression windows should be limited by available RAM now on 64-bit systems. The compression advantages on large files on 64-bit machines with large RAM are massive. The limit on 32-bit is still 2GB. The file format is no longer compatible with earlier versions of lrzip. Support for decompressing older formats is present, but all new files will be generated in the new format. Minor speedups were done. Decompression should no longer stall at 4GB boundaries for extended periods, making decompression much faster for files larger than 4GB. Many documentation and benchmark updates were made.
