BackupPC 4.1.0 contains some new features and several bug fixes:
- BackupPC_migrateV3toV4 optionally allows old 3.x backups to be migrated to 4.x format, eliminating the hardlinks used by 3.x. (BackupPC 4.x can view/browse/restore 3.x backups, so it's not necessary to run BackupPC_migrateV3toV4)
- modern CSS (from Ernesto Carrea)
- fixes to rsync restore (from Stephen Joyce)
- fixes to exponential backup expiry (from Alexander Moisseev)
- added template systemd files
- configure.pl adds a --config-only option for package builders (from Alexander Moisseev)
- various other fixes (see ChangeLog)
