Bugfixes:

• Major Bugfix: the writing of metadata file containing list of files belonging to a backup was bugged, which resulted in losing the information about one file per 4MB of metadata. Now the writing of metadata is done correctly. validate command can detect metadata corruption in backups produced by affected versions. Affected versions: 2.1.4, 2.1.5 and 2.2.1. Reported by Leonid Kraubner. More information can be found here: #132

• previously WAL retention didn`t retained WAL segments entitled to protection from WAL purge, now WAL retention works correctly

Improvements:

• new flag --force for restore command can be used to restore invalid backups.
• validation running during backup merge now does only file checksum comparison without block validation. It should speed up merge of compressed backups
