Allow internal symlinks to be suppressed when the repository is located on a filesystem that does not support symlinks. This does not affect any pgBackRest functionality, but the convenience link latest will not be created and neither will internal tablespace symlinks, which will affect the ability to bring up clusters in-place manually using filesystem snapshots.
This was introduced in an effort to make the html output XHTML 1.0 STRICT compliant because the standard does not allow / characters in anchors.
However, the / characters were changed to . in the anchors but not in the links. For now revert the anchors to / so further though can be given to this issue.
Bug Fixes:
* Fixed and issue that suppressed exceptions in PDF builds.
Features:
* Allow a source to be included as a section so large documents can be broken up.
* Added section link support to Markdown output.
* Added list support to PDF output.
* Added include option to explicitly build sources (complements the exclude option though both cannot be used in the same invocation).
* Added keyword-add option to add keywords without overriding the default keyword.
* Added debug option to doc.pl to easily add the debug keyword to documentation builds.
* Added pre option to doc.pl to easily add the pre keyword to documentation builds.
Refactoring:
* Improvements to markdown rendering.
* Remove code dependency on project variable, instead use title param.
Bug Fixes:
* Fixed an issue where asynchronous archiving was transferring one file per execution instead of transferring files in batches. This regression was introduced in v1.09 and affected efficiency only, all WAL segments were correctly archived in asynchronous mode. (Reported by Stephen Frost.)

Bug Fixes:
* Fixed an issue where a backup could error if no changes were made to a database between backups and only pg_control changed.
* Fixed an issue where tablespace paths with the same prefix would cause an invalid link error. (Reported by Nikhilchandra Kulkarni.)
Features:
* Added the stanza-create command to formalize creation of stanzas in the repository. (Contributed by Cynthia Shang.)
Refactoring:
* Removed extraneous use lib directives from Perl modules. (Suggested by Devrim Gündüz.)
Bug Fixes:
* Fixed missing variable replacements.
* Removed hard-coded host names from configuration file paths.
Documentation Features:
* Allow command-line length to be configured using cmd-line-len param.
* Added compact param to allow CSS to be embedded in HTML file.
* Added pretty param to produce HTML with proper indenting.
* Only generate HTML menu when required and don't require index page.
* Assign numbers to sections by default.
* VM mount points are now optional.
Bug Fixes:
* Fixed the check command to prevent an error message from being logged if the backup directory does not exist. (Fixed by Cynthia Shang.)
* Fixed error message to properly display the archive command when an invalid archive command is detected. (Reported by Jason O'Donnell.)
* Fixed an issue where the async archiver would not be started if archive-push did not have enough space to queue a new WAL segment. This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed. (Reported by Jens Wilke.)
* Fixed a remote timeout that occurred when a local process generated checksums (during resume or restore) but did not copy files, allowing the remote to go idle. (Reported by Jens Wilke.)
Features:
* Non-exclusive backups will automatically be used on PostgreSQL 9.6.
* Added the cmd-ssh option to allow the ssh client to be specified. (Suggested by Jens Wilke.)
* Added the log-level-stderr option to control whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior. (Suggested by Sascha Biberhofer.)
* Set application_name to "pgBackRest [command]" for database connections. (Suggested by Jens Wilke.)
* Check that archive_mode is enabled when archive-check option enabled.
Refactoring:
* Clarified error message when unable to acquire pgBackRest advisory lock to make it clear that it is not a PostgreSQL backup lock. (Suggested by Jens Wilke.)
* pgBackRest version number included in command start INFO log output.
* Process ID logged for local process start/stop INFO log output.

Bug Fixes:
* Fixed an issue where local processes were not disconnecting when complete and could later timeout. (Reported by Todd Vernick.)
* Fixed an issue where the protocol layer could timeout while waiting for WAL segments to arrive in the archive. (Reported by Todd Vernick.)
Refactoring:
* Cache file log output until the file is created to create a more complete log.
* Fixed an issue where local processes were not disconnecting when complete and could later timeout. (Reported by Todd Vernick.)
* Fixed an issue where the protocol layer could timeout while waiting for WAL segments to arrive in the archive. (Reported by Todd Vernick.)
Bug Fixes:
* Fixed an issue where tablespaces were copied from the master during standby backup.
* Fixed the check command so backup info is checked remotely and not just locally. (Fixed by Cynthia Shang.)
* Fixed an issue where retention-archive was not automatically being set when retention-archive-type=diff, resulting in a less aggressive than intended expiration of archive. (Fixed by Cynthia Shang.)
Features:
* Converted Perl threads to processes to improve compatibility and performance.
* Exclude contents of $PGDATA/pg_replslot directory so that replication slots on the master do not become part of the backup.
* The archive-start and archive-stop settings are now filled in backup.manifest even when archive-check=n.
* Additional warnings when archive retention settings may not have the intended effect or would allow indefinite retention. (Contributed by Cynthia Shang.)
* Experimental support for non-exclusive backups in PostgreSQL 9.6 rc1. Changes to the control/catalog/WAL versions in subsequent release candidates may break compatibility but pgBackRest will be updated with each release to keep pace.
Refactoring:
* Refactor of protocol minions in preparation for the new local minion.
* Remove obsolete thread index variable from File() module.
* Changed temporary file names to consistently use the .pgbackrest.tmp extension even if the destination file is compressed or has an appended checksum.
* Improve ASSERT error handling, safely check eval blocks, and convert $@ to $EVAL_ERROR.
* Fixed an issue where retention-archive was not automatically being set when retention-archive-type=diff, resulting in a less aggressive than intended expiration of archive.
* Additional warnings when archive retention settings may not have the intended effect or would allow indefinite retention.
* Closed#235: "Retention policy question" by adding documentation for archive retention.
