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().
* Move repository options into a separate section in command/command-line help. (Suggested by Stephen Frost.)
* Fix description of --online based on the command context.
* Remove vestigial repository options from backup command.

The options accommodate systems where CAs are not automatically found by IO::Socket::SSL, i.e. RHEL7, or to load custom CAs.
Suggested by Scott Frazer.
* Combine hardlink and non/compressed in synthetic tests to reduce test time and improve coverage.
* Change log level of hardlink logging to detail.
* Cast size in S3 manifest to integer.
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.)
* Refactor Ini.pm to facilitate testing.
* Complete statement/branch coverage for Ini.pm.
* Improved functions used to test/munge manifest and info files.
* 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.)
* Simplify locking scheme. Now, only the master process will hold write locks (archive-push, backup) and not all the local and remote worker processes as before.
The stanza-upgrade command provides a mechanism for upgrading a stanza after upgrading to a new major version of PostgreSQL.
Contributed by Cynthia Shang.
* Allow logging to be suppressed via logDisable() and logEnable().
* Added more flexibility in initializing and cleaning up after modules and tests.
* testResult() suppresses logging and reports exceptions.
* testException() allows messages to be matched with regular expressions.
* Refactor name/locations of common modules that setup test environments.
