New Features ------------ Configuration ~~~~~~~~~~~~~ * Project owners can define `receive.maxObjectSizeLimit` in the link:http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/config-gerrit.html#receive.maxObjectSizeLimit[ project configuration] to further reduce the global setting. * Site administrators can define a link:http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/config-mail.html#_footer_vm[ footer template] that will be appended to the end of all outgoing emails after the 'ChangeFooter' and 'CommentFooter'. * New `topic-changed` hook and stream event is fired when a change's topic is edited from the Web UI or via a REST API. * New options `--list-plugins` and `--install-plugins` on the link:[http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/pgm-init.html[ site initialization command]. * New `auth.httpDisplaynameHeader` and `auth.httpEmailHeader` in the link:[http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/config_gerrit.html#_a_id_auth_a_section_auth[ authentication configuration]. + When using HTTP-based authentication, the SSO can be delegated to check not only the user credentials but also to fetch the full user-profile. + With the config properties `auth.httpDisplaynameHeader` and `auth.httpEmailHeader` it is possible to configure the name of the headers used for propagating this extra information and enforce them on the user profile during login and beyond. * link:http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/config_gerrit.html#_a_id_httpd_a_section_httpd[ Customizable registration page for HTTP authentication]. * link:http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/config_gerrit.html#_a_id_httpd_a_section_httpd[ Configurable external `robots.txt` file]. * Support for link:http://gerrit-documentation.googlecode.com/svn/Documentation/2.8/database-setup.html#createdb_oracle[ Oracle database].

Change Screens ^^^^^^^^^^^^^^ * New button to cherry-pick the change to another branch. * When issuing a rebase via the Web UI, the committer is now the logged in user, rather than "Gerrit Code Review". + If the user has more than one email address, the preferred email address will be used. * Default user's full name to git committer name if user has not configured a full name in their profile. * Include comment author attributes in comment panels. + Comment author's email address and name are included as attributes in comment panels. This makes it easier to filter out CI-based comments using user scripts. * Copy reviewed flag to new patch sets for identical files. + If a user has already seen and reviewed a file, the 'reviewed' flag is forwarded on to the next patch set when the content of the file in the next patch set is identical to the reviewed file.
