pitrery 1.12 has just been released.
This new version adds some new features and improvements:
Fix the restore so that the backup_label is restored when used with PostgreSQL 9.6. Users of version 1.11 are encouraged to upgrade as theirs backups won’t be restored properly unless they copy the backup_label file from the backup manually.
New -m option for archive_xlog to chmod the archived file to the specified octal permission bits
The CHANGELOG file in the source code contains a more complete list of changes in this version.
