- Bugfix: fixed undefined behaviour in case of undefined compression algorithm
- Bugfix: correctly calculate backup size after MERGE
- Bugfix: fixed MERGE of compressed and uncompressed backups
- Bugfix: remove unnecessary remaining files after MERGE
- Bugfix: consider target LSN (--lsn parameter) during validating WAL
- Improvement: check backup program_version during VALIDATE, do not support forward compatibility
- Improvement: improve Windows support
- Improvement: improve support of tablespaces within PGDATA
- Bugfix: changing log-level-file and log-level-console via set-config now works correctly
- Bugfix: WAL files crc comparison done by archive-push is now works correctly, previously it`s was always giving mismatch
- Impromevent: PG_STOP_BACKUP_TIMEOUT now governed by archive-timeout option
- Impromevent: CRC-32c now used to calculate crc for data and WAL files, previously a slower CRC-32 was used
- Impromevent: cold replica can be backuped without false-positive WAL timeouts
- Impromevent: for PG >= 10 pg_stop_backup now called without wait_for_archive flag
- Impromevent: minor fixes for Windows build
- Major bugfix: incorrect handling of badly compressed blocks, previously there was a risk to restore block in uncompressed state, if compressed size was equal or larger than BLCKSZ
- Impromevent: backup from replica >= 9.6 no longer need connection to master
- Workaround: wrong minRecPoint in PostgreSQL thanks to commit 8d68ee6(block from future), overwrite minRecPoint with latest applied LSN
- Impromevent: merge is now considered stable feature
- Impromevent: validation now use more conservative and paranoid approach to file validation, during validation pg_probackup also check block checksumm, make sanity check based on block header information and try to detect blocks from future
- New validate/restore options:
'--skip-block-validation' - disable aforementioned approach to file validation
- Multiple minor fixes
