 Here's a (incomplete) list of some major changes:
 
- * more open, faster paced development (see `issue #1 <https://github.com/borgbackup/borg/issues/1>`_)
- * lots of attic issues fixed (see `issue #5 <https://github.com/borgbackup/borg/issues/5>`_)
- * less chunk management overhead via --chunker-params option (less memory and disk usage)
- * faster remote cache resync (useful when backing up multiple machines into same repo)
- * compression: no, lz4, zlib or lzma compression, adjustable compression levels
- * repokey replaces problematic passphrase mode (you can't change the passphrase nor the pbkdf2 iteration count in "passphrase" mode)
- * simple sparse file support, great for virtual machine disk files
- * can read special files (e.g. block devices) or from stdin, write to stdout
- * mkdir-based locking is more compatible than attic's posix locking
- * uses fadvise to not spoil / blow up the fs cache
- * better error messages / exception handling
- * better logging, screen output, progress indication
- * tested on misc. Linux systems, 32 and 64bit, FreeBSD, OpenBSD, NetBSD, Mac OS X
