NOTE TO PACKAGERS: This is last feature release to support the autoconf/make build. Please migrate to meson if you have not already done so. 2.54.X patch releases (if any) will continue to support autoconf/make.
Bug Fixes:
* Fix PostgreSQL query performance for large datasets. (Fixed by Thibault Vincent, David Steele. Reviewed by David Christensen, Antoine Millet. Reported by Antoine Millet.)
Features:
* Allow repositories on versioned storage to be read at a target time. (Reviewed by Stefan Fercot, David Christensen.)
* Allow requested standby backup to proceed with no standby. (Reviewed by Stefan Fercot.)
Improvements:
* Summarize backup reference list for info command text output. (Contributed by Stefan Fercot. Reviewed by David Steele.)
* Refresh web-id token for each S3 authentication. (Contributed by Brent Graveland. Reviewed by David Steele.)
* Correctly display current values for indexed options in help. (Reviewed by David Christensen.)
* Save backup.info only when contents have changed. (Reviewed by Stefan Fercot.)
* Remove limitation on reading files in parallel during restore. (Reviewed by David Christensen.)
* Improve SFTP error messages. (Contributed by Reid Thompson. Reviewed by David Steele.)
Documentation Features:
* Add performance tuning section to user guide. (Reviewed by Stefan Fercot.)
Documentation Improvements:
* Clarify source for data_directory. (Contributed by Stefan Fercot. Reviewed by David Steele. Suggested by Matthias.)
* Better logic for deciding when a summary should be lower-cased. (Suggested by Daniel Westermann.)
IMPORTANT NOTE: The log-level-stderr option default has been changed from warn to off. This makes it easier to capture errors when only redirecting stdout. To preserve the prior behavior set log-level-stderr=warn.
NOTE TO PACKAGERS: The lz4 library is now required by the meson build.
NOTE TO PACKAGERS: Compiler support for __builtin_clzl() and __builtin_bswap64() is now required by the meson build.
Bug Fixes:
* Fix SFTP renaming failure when file already exists. (Fixed by Reid Thompson. Reviewed by David Steele. Reported by ahmed112212.)
Features:
* Allow backups to run concurrently on different repositories. (Reviewed by Reid Thompson, Stefan Fercot.)
* Support IP-based SANs for TLS certificate validation. (Contributed by David Christensen. Reviewed by David Steele.)
Improvements:
* Default log-level-stderr option to off. (Reviewed by Greg Sabino Mullane, Stefan Fercot.)
* Allow alternative WAL segment sizes for PostgreSQL ≤ 10. (Contributed by Viktor Kurilko. Reviewed by David Steele.)
* Add hint to check SFTP authorization log. (Contributed by Vitalii Zurian. Reviewed by Reid Thompson, David Steele.)
Documentation Improvements:
* Clarify archive-push multi-repo behavior. (Reviewed by Stefan Fercot.)
These functions will be useful for optimizing varint-128 functions.
Require them in the meson build before adding new code in case there are problems with packaging.
We would like to use lz4 for protocol compression instead of gz but first we need to make sure this is not going to cause a problem for packaging.
To do this make lz4 required in meson but make no changes to the code so this is an easy revert for packagers if there is an issue.
NOTE TO PACKAGERS: The build system for pgBackRest is now meson. The autoconf/make build will not receive any new features and will be removed after a few releases.
Features:
* Add GCS batch delete support. (Reviewed by Reid Thompson.)
* S3 SSE-C encryption support. (Reviewed by Tim Jones. Suggested by Tim Jones.)
* PostgreSQL 17 support. (Reviewed by Stefan Fercot.)
Improvements:
* Allow explicit disabling of optional dependencies in meson builds. (Contributed by Michael Schout. Reviewed by David Steele.)
* Dynamically find python in meson build. (Contributed by Michael Schout. Reviewed by David Steele.)
* Tag pgbackrest build target in meson as installable. (Contributed by Bradford Boyle. Reviewed by David Steele.)
Documentation Improvements:
* Update start/stop documentation to reflect actual functionality. (Reviewed by Stefan Fercot.)
This is better than requiring a python3 binary to be on the path because some installations might have, e.g. python3.9.
Also add the python3-distutils package to Debian builds to make this work.
On some platforms, e.g. FreeBSD, there is a requirement to allow the user to disable support for features even when the required library is present.
Introduce tri-state options for the optional features: auto mimics the current behavior and is the default, enable requires libraries for the feature to be present, and disable disables the feature without checking the libraries.
NOTE TO PACKAGERS: The build system for pgBackRest is now meson. The autoconf/make build will not receive any new features and will be removed after a few releases.

The ZLIB_CONST macro may be used since 1.2.5.2 (17 Dec 2011) to specify that the input buffers are const. This is sufficiently old to cover all non-EOL distributions, i.e. everything we test on.
Compiling on older distributions may generate warnings but will continue to work.

* Updates and clarifications to index page. (Reviewed by Stefan Fercot.)
* Add dark mode to the website. (Suggested by Stephen Frost.)
The libbacktrace feature has not been working since the move to meson because libbacktrace detection was not added to the meson build. Add libbacktrace to meson and improve the feature so that it can be compiled into release builds.
The prior implementation fetched line numbers with each stack trace push. Not only was this slow but it missed any functions that were not being tracked on our stack.
Instead just examine the backtrace when an error happens and merge it with the info we have on our stack. If the backtrace is not available then the output remains as before.
Also remove --backtrace from test.pl since the library is now auto-detected.
Leave this library out of the production build for now to give it a little time to shake out in testing.
This is immediately useful because it will detect any extern'd functions or variables that are not being used. It also detects functions or variables that are declared but not defined.
If a FV/VR_EXTERN macro is missing it will be detected either because of a mismatch in the declaration/definition or because a new defined symbol will appear in the nm test.
Eventually the unity build will be used to create a more optimized pgbackrest binary but that will need to wait.

v0.45 ships with Ubuntu 18.04, which is currently the oldest distro we support. We may never do a Meson release on Ubuntu 18.04 but this allows us to start running unit tests with Meson in the meantime.
Some more granular options are not available so we use buildtype in more places.
The check for a in-tree autoconf/make build had to be removed since the filesystem APIs are not available.
Finally, alias_target was removed. This means that full paths must be used for build targets, which does not seem too bad. For instance, test/src/test-pgbackrest must now be used as a build target instead of simple test-pgbackrest.
This provides reproducible builds and minimizes the file path in debug messages, just like an in-tree make build.
For test source, prefix with test/ in case there are any module name collisions.
Having the test harness in C will allow us to remove duplicated Perl code and test on systems where Perl support is not present.
Custom harnesses and shims are currently not implemented, which means only the following tests in the common module will run: error, stack-trace, type-convert, assert-on, mem-context, time, encode, type-object, type-string, type-list, type-buffer, type-variant, reg-exp, log.
The experimental test harness is being committed with partial functionality so it can be used in Windows development. The remaining features will follow as needed.
The meson builds are still experimental so for now the configure/make build process is preferred for release builds. This message should help prevent any automated build systems from picking up meson instead.
