Bug Fixes:
* Fixed an issue that could cause copying large manifests to fail during restore. (Reported by Craig A. James.)
* Fixed incorrect WAL offset for 32-bit architectures. (Fixed by Javier Wilson.)
* Fixed an issue retrieving WAL for old database versions. After a stanza-upgrade it should still be possible to restore backups from the previous version and perform recovery with archive-get. However, archive-get only checked the most recent db version/id and failed. Also clean up some issues when the same db version/id appears multiple times in the history. (Fixed by Cynthia Shang. Reported by Clinton Adams.)
* Fixed an issue with invalid backup groups being set correctly on restore. If the backup cannot map a group to a name it stores the group in the manifest as false then uses either the owner of $PGDATA to set the group during restore or failing that the group of the current user. This logic was not working correctly because the selected group was overwriting the user on restore leaving the group undefined and the user incorrectly set to the group. (Reported by Jeff McCormick.)
* Fixed an issue passing parameters to remotes. When more than one db was specified the path, port, and socket path would for db1 were passed no matter which db was actually being addressed. (Reported by Uspen.)
Features:
* Repository encryption support. (Contributed by Cynthia Shang, David Steele.)
db-path was the only option with a hint so the feature seemed wasteful. All missing stanza options now output the same hint without needing configuration.
Bug Fixes:
* The archive_status directory is now recreated on restore to support PostgreSQL 8.3 which does not recreate it automatically like more recent versions do. (Reported by Stephen Frost.)
* Fixed an issue that could cause the empty archive directory for an old PostgreSQL version to be left behind after a stanza-upgrade. (Fixed by Cynthia Shang.)
Features:
* Modified the info command (both text and JSON output) to display the archive ID and minimum/maximum WAL currently present in the archive for the current and prior, if any, database cluster version. (Contributed by Cynthia Shang.)
* Added --backup-ssh-port and --db-ssh-port options to support non-default SSH ports. (Contributed by Cynthia Shang.)
Refactoring:
* Retry when S3 returns an internal error (500).
* Add bIgnoreMissing parameter to Local->manifest().
Modified the info command (both text and JSON output) to display the archive ID and minimum/maximum WAL currently present in the archive for the current and prior, if any, database cluster version.

Bug Fixes:
* Fixed an issue that prevented tablespaces from being backed up on PostgreSQL ≤ 8.4.
* Fixed missing flag in C library build that resulted in a mismatched binary on 32-bit systems. (Reported by Adrian Vondendriesch.)
Features:
* Add s3-repo-ca-path and s3-repo-ca-file options to accommodate systems where CAs are not automatically found by IO::Socket::SSL, i.e. RHEL7, or to load custom CAs. (Suggested by Scott Frazer.)
Refactoring:
* Harden protocol handshake to handle race conditions.
* Fixed misleading error message when a file was opened for write in a missing directory.
* Change log level of hardlink logging to detail.
* Cast size in S3 manifest to integer.
* Rename Archive modules to remove redundancy.
* Improve S3 error reporting.
* Minor optimizations to package loads and ordering for archive-get and archive-push commands.
Bug Fixes:
* Fixed the info command so the WAL archive min/max displayed is for the current database version. (Fixed by Cynthia Shang.)
* Fixed the backup command so the backup-standby option is reset (and the backup proceeds on the master) if the standby is not configured and/or reachable. (Fixed by Cynthia Shang.)
* Fixed config warnings raised from a remote process causing errors in the master process. (Fixed by Cynthia Shang.)
Features:
* Amazon S3 repository support. (Reviewed by Cynthia Shang.)
Refactoring:
* Refactor storage layer to allow for new repository filesystems using drivers. (Reviewed by Cynthia Shang.)
* Refactor IO layer to allow for new compression formats, checksum types, and other capabilities using filters. (Reviewed by Cynthia Shang.)
* Move modules in Protocol directory in subdirectories.
* Move backup modules into Backup directory.
Bug Fixes:
* Fixed an issue where read-only operations that used local worker processes (i.e. restore) were creating write locks that could interfere with parallel archive-push. (Reported by Jens Wilke.)
Features:
* Added the stanza-upgrade command to provide a mechanism for upgrading a stanza after upgrading to a new major version of PostgreSQL. (Contributed by Cynthia Shang.)
* Added validation of pgbackrest.conf to display warnings if options are not valid or are not in the correct section. (Contributed by Cynthia Shang.)
Refactoring:
* Simplify locking scheme. Now, only the master process will hold write locks (for archive-push and backup commands) and not all local and remote worker processes as before.
* Refactor Ini.pm to facilitate testing.
* Do not set timestamps of files in the backup directories to match timestamps in the cluster directory. This was originally done to enable backup resume, but that process is now implemented with checksums.
* Improved error message when the restore command detects the presence of postmaster.pid. (Suggested by Yogesh Sharma.)
* Renumber return codes between 25 and 125 to avoid PostgreSQL interpreting some as fatal signal exceptions. (Suggested by Yogesh Sharma.)
* The backup and restore commands no longer copy via temp files. In both cases the files are checksummed on resume so there's no danger of partial copies.
* Allow functions to accept optional parameters as a hash.
* Refactor File->list() and fileList() to accept optional parameters.
* Refactor backupLabel() and add unit tests.
* Silence some perl critic warnings. (Contributed by Cynthia Shang.)
Bug Fixes:
* Fixed an issue where tables over 1GB would report page checksum warnings after the first segment. (Reported by Stephen Frost.)
* Fixed an issue where databases created with a non-default tablespace would raise bogus warnings about pg_filenode.map and pg_internal.init not being page aligned. (Reported by blogh.)
Refactoring:
* Improved the code and tests for fileManifest() to prevent a possible race condition when files are removed by the database while the manifest is being built.
Bug Fixes:
* Fixed a regression introduced in v1.13 that could cause backups to fail if files were removed (e.g. tables dropped) while the manifest was being built. (Reported by Navid Golpayegani.)
Refactoring:
* Refactor FileCommon::fileManifest() and FileCommon::fileStat to be more modular to allow complete branch/statement level coverage testing.
Bug Fixes:
* Fixed an issue where an archive-push error would not be retried and would instead return errors to PostgreSQL indefinitely (unless the .error file was manually deleted). (Reported by Jens Wilke.)
* Fixed a race condition in parallel archiving where creation of new paths generated an error when multiple processes attempted to do so at the same time. (Reported by Jens Wilke.)
Refactoring:
* Improved performance of wal archive min/max provided by the info command. (Suggested by Jens Wilke.)
