 https://www.gerritcodereview.com/download/gerrit-2.12.war]

 Important Notes
 ---------------

 *WARNING:* This release contains schema changes.  To upgrade:
 ----
   java -jar gerrit.war init -d site_path
 ----

 *WARNING:* Upgrading to 2.12.x requires the server be first upgraded to 2.8 (or
 2.9) and then to 2.12.x. If you are upgrading from 2.8.x or later, you may ignore
 this warning and upgrade directly to 2.12.x.

 *WARNING:* When upgrading from version 2.8.4 or older with a site that uses
 Bouncy Castle Crypto, new versions of the libraries will be downloaded. The old
 libraries should be manually removed from site's `lib` folder to prevent the
 startup failure described in
 link:https://code.google.com/p/gerrit/issues/detail?id=3084[Issue 3084].

 *WARNING:* The Solr secondary index is no longer supported. With this release
 the only supported secondary index is Lucene.


 Release Highlights
 ------------------

 This release includes the following new features. See the sections below for
 further details.

 * New "Submit Whole Topic" / "Submitted Together" workflow.

 * Support for GPG Keys and signed pushes.


 New Features
 ------------

 New Change Submission Workflow
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 * New "Submit Whole Topic" setting.
 +
 When the
 link:https://gerrit-documentation.storage.googleapis.com/Documentation/2.12/config-gerrit.html#change.submitWholeTopic[
 `change.submitWholeTopic`] setting is enabled, all changes belonging to the same
 topic will be submitted at the same time.
 +
 This setting is disabled by default.

 * Submission of changes may include ancestors.
 +
 If a change is submitted that has submittable ancestor changes, those changes
 will also be submitted.

 * The merge queue is removed.
 +
 Changes that cannot be submitted due to missing dependencies will no longer
 enter the "Submitted, Merge Pending" state.


 GPG Keys and Signed Pushes
 ~~~~~~~~~~~~~~~~~~~~~~~~~~

 * TODO: Details


 Secondary Index
 ~~~~~~~~~~~~~~~

 * link:http://code.google.com/p/gerrit/issues/detail?id=3333[Issue 3333]:
 Support searching for changes by author and committer.
 +
 Changes are indexed by the git author and committer of the latest patch set,
 and can be searched with the `author:` and `committer:` operators.
 +
 Changes are matched on either the exact whole email address, or on parts of the
 name or email address.

 * Add `from:` search operator to match by owner of change or author of comments.

 * Add `commentby:` search operator to search byt author of comments.

 * Change the `topic:` search operator to search by the exact topic name.

 * link:http://code.google.com/p/gerrit/issues/detail?id=3291[Issue 3291]:
 Add `has:edit` search operator to match changes that have change edits on them.

 * Allow configuration of maximum query size.
 +
 link:https://gerrit-documentation.storage.googleapis.com/Documentation/2.12/config-gerrit.html#index.maxTerms[
 `index.maxTerms`] can be set to limit the number of leaf index terms.

 * Expose Lucene index writers for plugins.
 +
 Plugins can now be written to allow runtime reconfiguration of various Lucene
 performance related parameters.

 * Make Lucene index writers auto-commit writers.
 +
 Plugins can now temporarily turn on auto-committing in situations where it makes
 sense to enforce all changes to be written to disk ASAP.

 ~~~~~~~~

 New REST API endpoints and new options on existing endpoints.

 ^^^^

 * Support filtering by substring and regex in the list tags endpoint.

 * Support pagination with `--start` and `--end` in the list tags endpoint.


 Other
 ~~~~~

 * Add support for SSH ZLib Compression.
 +
 To enable compression use the
 link:https://gerrit-documentation.storage.googleapis.com/Documentation/2.12/config-gerrit.html#sshd.enableCompression[
 `sshd.enableCompression` setting].

 * link:http://code.google.com/p/gerrit/issues/detail?id=2061[Issue 2061]
 Add Support for `git-upload-archive`.
 +
 This allows use the standard `git archive` command to create an archive

 * Add a background job to automatically abandon inactive changes.
 +

 Apache Derby database].

 * Download commands plugin: Use commit IDs for download commands when change refs are hidden.
 +
 Git has a configuration option to hide refs from the initial advertisement
 (`uploadpack.hideRefs`). This option can be used to hide the change refs from
 the client. As consequence this prevented fetching changes by change ref from
 working.
 +
 Setting `download.checkForHiddenChangeRefs` in the `gerrit.config` to true
 allows the download commands plugin to check for hidden change refs.
