rdiff-backup will now exit by default if it thinks another rdiff-backup process is currently working on the same repository.
Empty error_log, mirror_metadata, extended_attribute, and access_control_lists files will no longer be gzipped (suggestion by Hans F.
Nordhaug).
Fix for restoring files in directories with really long names.
Added supplementary rdiff-backup-statistics utility for parsing rdiff-backup's statistics files (originally based off perl script by Dean Gaudet).
rdiff-backup should now use much less memory than v1.1.1-1.1.4 if you have lots of hard links.
