Version number specified in
pg_probackup.confis now preserved when this file gets updated, which allows to correctly identify pg_probackup version used to take the backup.
Fixed an issue with restoring compressed file blocks and enhanced checks for compression errors. Previously, pg_probackup could not restore file blocks that the
zlibalgorithm failed to compress during backup. This issue could not be detected by the built-in pg_probackup validation mechanism as it occurs on a lower level that validation itself. You are recommended to re-validate existing backups using this pg_probackup version.
Improved validation algorithm. Files are now validated block by block by default, not only in case of file-level checksum mismatch. You can disable this behavior using the
Allowed restarting a backup merge if the previous attempt has been interrupted.
Allowed taking backups from standby servers without connecting to the master. Besides, pg_probackup now uses its built-in mechanism to determine the consistency point, so there is no risk that backups from standby contain any inconsistent data.

PL/Perl now requires ActivePerl 5.26.
32-bit Postgres Pro version is no longer provided.
