This release contains schema changes. To upgrade:
java -jar gerrit.war init -d site_path
Gerrit now requires Java Runtime Environment (JRE) version 8. It is no longer possible to run Gerrit on JRE 7.
The Bouncy Castle Crypto API libraries are now distributed in the Gerrit .war file rather than being downloaded during site initialization. When upgrading from a previous version of Gerrit, previously downloaded Bouncy Castle .jar files remaining in the site's /lib folder will be disabled by appending .disabled to the file name.
Support for HTTP Digest Authentiation is removed.
With the move to NoteDB, the per-account data (including the HTTP password) will be stored in a branch in the All-Users repo, where it is subject to Gerrit ACLs. Since these are notoriously hard to setup correctly, we want to avoid storing the password in plaintext.
Existing passwords will be migrated to a hashed password during site initialization when upgrading from an earlier version of Gerrit.
This release deprecates the use of Velocity mail templates. In a future release support will be removed and it will be necessary to upgrade custom mail templates to Soy files.
The permissions “Push Annotated Tag” and “Push Signed Tag” are renamed to “Create Annotated Tag” and “Create Signed Tag”. Existing project configurations using the old permission names will be migrated during site initialization.
Changes may be assigned to a specific user. This allows a workflow where the user that is assigned to a change is responsible for reviewing the change and/or passing the assignment on to another user.
In the UI, changes assigned to the currently logged in user are highlighted.
A new assignee: search predicate allows to find changes assigned to a given user.
Gerrit email messages are made easier to read by sending HTML content parts in addition to the existing text email content. This is enabled by default, and can be disabled by setting sendemail.html to false.
Users can opt to always receive plaintext emails by setting the Email Format preference.
Mail templates can now be written using [https://developers.google.com/closure/templates/](Closure Templates) (Soy). Mail templates written in Velocity (VTL) are deprecated but still supported. Support for VTL will be dropped in the next release.
Gerrit now supports receiving review comments by email.
Gerrit now includes a new user interface, referred to as “PolyGerrit”, based on Polymer.
The UI can be switched between PolyGerrit and GWT by clicking the “New UI” and “Old UI” links in the site footer. Alternatively, the UI can be switched by adding ?polygerrit=1 or ?polygerrit=0 to the URL.
Note that PolyGerrit is still under development. Most use cases are supported, but there are still some missing features compared to the GWT UI.
