Buildbot

Bug fixes
---------

- Fixed several occasional data update glitches in web frontend
- Fixed display of newly added builds in Workers view in the web frontend.

Bug fixes
---------

- Fixed a regression where ``GitPoller`` would no longer register new changes (regression introduced in 3.11.3 in 7554)

Bug fixes
---------

- Fixed a bug that caused ``GitPoller`` running with git configured with ``fetch.prune=true`` parameter to fail.
- Fixed a bug that caused ``GitPoller`` to miss changes when buildbot is reconfigured
- Reduced length of directory names produced by ``GitPoller`` internally. Long directory names could potentially break ``GitPoller`` on filesystems with low path and name length limits.
- Removed credentials from ``repourl`` used in the tracker branch name.

Deprecations and Removals
-------------------------

- The ``pollinterval`` (note the small ``i``) argument of various change sources has been deprecated with a warning in favor of ``pollInterval``.

Features
--------

- Added ``MessageFormatterFunctionRaw`` which allows complete customization of messages to be emitted. This feature has been available since 3.11.0 and only the announcement has been missed.

Bug fixes
---------

- Fixed an error in HgPoller when repository initialization fails (7488)
- Updated `Makefile` to handle Windows paths and Python.
- Added a web configuration setting to select whether build completion or start times are displayed.
- Added revision info column in the web frontend.
- Fixed steps raw log download button.
- Fixed a regression in React UI that prevented hosting Buildbot at a custom URL prefix. This allows to support multiple Buildbot instances on a single server.

Improved Documentation
----------------------

- Documented that ``ChangeSource`` does not support secrets (or any other renderables), best practice of not encoding secret values in changes and alternative solutions when secret values in changes are unavoidable. ``ChangeSource`` accidentally supported renderable arguments up until Buildbot 3.7, but this was not documented behavior.

Bug fixes
---------

- `GitPoller` now ensures the SSH Private Key it uses has a trailing newline.
- Migrated off python-future which prevented installing Buildbot on distributions that do not provide
that package.
- Fixed sporadic navigation to builders page when new build is started (7307).

Bug fixes
---------

- Declare Python 3.12 compatibility in generated packages of master and worker

Features
--------

- Added a new WSGI dashboards plugin for React frontend. It is backwards compatible with AngularJS one but may require changes in CSS styling of displayed web pages.
- Implemented a report generator (``BuildSetCombinedStatusGenerator``) that can access complete information about a buildset.
- Low level database API now has ``get_sourcestamps_for_buildset`` to get source stamps for a buildset. "/buildsets/:buildsetid/sourcestamps" endpoint has been added to access this from the Data API.
- Added buildset information to dictionaries returned by report generators.
- Added a way to pass additional reporter-specific data to Reporters. Added ``extra_info_cb`` argument to ``MessageFormatter`` for this use case.
- Implemented support for report generators in ``GerritStatusPush``.

Deprecations and Removals
-------------------------

- The ``reviewCB``, ``reviewArg``, ``startCB``, ``startArg``, ``summaryCB``, ``summaryArg``, ``builders`` , ``wantSteps``, ``wantLogs`` arguments of ``GerritStatusPush`` have been deprecated.
