GWT UI is deprecated
PolyGerrit is now the default UI
Experimental Dark Mode in PolyGerrit.
Inline editing support in PolyGerrit UI.
Redesigned UI for PolyGerrit based on material design.
New CommonMark/Markdown parser.
This release contains schema changes. To upgrade:
java -jar gerrit.war init -d site_path
For logging Gerrit is now using Flogger instead of SLF4J. The logging backend is still LOG4J.
The Flogger LOG4J backend is configured by a system property (flogger.backend_factory=com.google.common.flogger.backend.log4j.Log4jBackendFactory#getInstance
) that must be set for logging to work. There is an init step that automatically sets this system property in the gerrit.config
file and in addition Gerrit tries to set this system property automatically on startup if it isn't set yet. However for some setups you may need to do additional actions to make sure that this system property is set.
In addition there is a system property that needs to be set for request tracing (flogger.logging_context=com.google.gerrit.server.logging.LoggingContext#getInstance
). Also this system property is automatically set in the gerrit.config
file by an init step and in addition Gerrit tries to set this system property automatically on startup if it isn't set yet. However for some setups you may need to do additional actions to make sure that this system property is set.
SLF4J can still be used by plugins, but using SLF4J in plugins is deprecated and with the next Gerrit release SLF4J will no longer be exported as part of the Gerrit plugin API jar. This means from the next release on plugins must either migrate to Flogger or have an own dependency on SLF4J.
Gerrit 2.16 introduces a new secondary index for projects. The initial version of this index must be created by running the offline reindex before starting Gerrit:
java -jar gerrit.war reindex --index projects -d site_path
The group index got two new fields upon which Gerrit 2.16 depends. For this reason, the following command to offline reindex the group index must be executed as well:
java -jar gerrit.war reindex --index groups -d site_path
The offline reindex for groups should also be run on Gerrit slave hosts.
Note that it is not necessary to reindex the changes and accounts indexes offline. These will automatically be reindexed by the online reindexer after starting Gerrit, assuming you were migrating from v2.15.
NoteDb is the preferred storage for changes and you are strongly advised to migrate changes from ReviewDb when upgrading to Gerrit v2.16 from either v2.14 or v2.15.
See more information about the migration process to NoteDb in the Gerrit Documentation:
NOTE: ReviewDb is still technically available on Gerrit v2.16. However, upgrade to NoteDb is strongly recommended, although not enforced during migration. The next version of Gerrit (v3.0) won't support ReviewDb anymore.
From 2.16 GWT UI is deprecated and will be removed in a future version.
In version 2.14 support for Soy templates was added. For backwards compatibility, support for Velocity templates (VTL) was kept.
In version 2.16 support for VTL is completely removed. Site administrators must replace any Velocity templates (.vm
files in $site/etc/mail/
) with the equivalent Soy templates before upgrading to this version.
The possibility to push to refs/changes
is now disabled by default. It is still possible to enable it in the gerrit config by setting receive.allowPushToRefsChanges to true.
Some proxies, which are not under client control, prohibit DELETE requests with bodies. DELETE requests with bodies could work on a first attempt, but could fail afterwards because a server they have no control over was updated. In this case, client users could be in trouble if they were not notified.
Therefore, we have decided to no longer recommend sending DELETE requests with bodies. They will continue to work in this release but should be considered as deprecated and will be removed in the next release.
flexmark-java is a Java implementation of CommonMark 0.28 spec parser using the blocks first, inlines after Markdown parsing architecture.
Its strengths are speed, flexibility, Markdown source element based AST with details of the source position down to individual characters of lexemes that make up the element and extensibility, compared to Pegdown speed that was, in general, less than ideal and for pathological input either hangs or practically hangs during parsing.
Tracing can now be enabled for single requests. If a request is traced a unique trace ID is attached to all logs that are triggered by the request. In addition all logs are enforced regardless of the configured log level. Given the trace ID an administrator can find the trace in the error log and debug issues more easily. Detailed information about request tracing can be found in the request tracing documentation.
