* Build containers from scratch for more accurate testing.
* Allow environment load to be skipped.
* Allow bash wrapping to be skipped.
* Allow forcing a command to run as a user without sudo.
Bug Fixes:
* Fix potential buffer overrun in error message handling. (Reported by Lætitia.)
* Fix archive write lock being taken for the synchronous archive-get command. (Reported by Uspen.)
Improvements:
* Embed exported C functions and Perl modules directly into the pgBackRest executable.
* Use time_t instead of __time_t for better portability. (Suggested by Nick Floersch.)
* Print total runtime in milliseconds at command end.
Low-level functions only include stack trace in test builds while higher-level functions ship with stack trace built-in. Stack traces include all parameters passed to the function but production builds only create the parameter list when the log level is set high enough, i.e. debug or trace depending on the function.
* Allow more than one test to provide coverage for the same module.
* Add option to disable valgrind.
* Add option to disabled coverage.
* Add option to disable debug build.
* Add option to disable compiler optimization.
* Add --dev-test mode.
Bug Fixes:
* Fix directory syncs running recursively when only the specified directory should be synced. (Reported by Craig A. James.)
* Fix archive-copy throwing "path not found" error for incr/diff backups. (Reported by yummyliu, Vitaliy Kukharik.)
* Fix failure in manifest build when two or more files in PGDATA are linked to the same directory. (Reported by Vitaliy Kukharik.)
* Fix delta restore failing when a linked file is missing.
* Fix rendering of key/value and list options in help. (Reported by Clinton Adams.)
Features:
* Add asynchronous, parallel archive-get. This feature maintains a queue of WAL segments to help reduce latency when PostgreSQL requests a WAL segment with restore_command.
* Add support for additional pgBackRest configuration files in the directory specified by the --config-include-path option. Add --config-path option for overriding the default base path of the --config and --config-include-path option. (Contributed by Cynthia Shang.)
* Add repo-s3-token option to allow temporary credentials tokens to be configured. pgBackRest currently has no way to request new credentials so the entire command (e.g. backup, restore) must complete before the credentials expire. (Contributed by Yogesh Sharma.)
Improvements:
* Update the archive-push-queue-max, manifest-save-threshold, and buffer-size options to accept values in KB, MB, GB, TB, or PB where the multiplier is a power of 1024. (Contributed by Cynthia Shang.)
* Make backup/restore path sync more efficient. Scanning the entire directory can be very expensive if there are a lot of small tables. The backup manifest contains the path list so use it to perform syncs instead of scanning the backup/restore path.
* Show command parameters as well as command options in initial info log message.
* Rename archive-queue-max option to archive-push-queue-max to avoid confusion with the new archive-get-queue-max option. The old option name will continue to be accepted.

Many options that were set per test can instead be inferred from the types, i.e. container, c, expect, and individual.
Also finish renaming Perl unit tests with the -perl suffix.
* Add storageCopy(), storageMove(), and storagePathSync().
* Separate StorageFile object into separate read and write objects.
* Abstract out Posix file read/write objects.
