## Important Notes

### Schema Changes

This release contains schema changes. To upgrade:

``` sh
  java -jar gerrit.war init -d site_path
```

### Java 8

Gerrit now requires Java Runtime Environment (JRE) version 8. It is no longer
possible to run Gerrit on JRE 7.

### Bouncy Castle Libraries

The [Bouncy Castle Crypto API libraries](https://www.bouncycastle.org/) 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.

### HTTP Digest Authentication Removed

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.

### Deprecation of Velocity Email Templates

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.

### Tag Permissions

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.

## New Features

### Change Assignee

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.

### Delete Changes

* [Issue 4509](https://bugs.chromium.org/p/gerrit/issues/detail?id=4509):
Open and Abandoned changes can be deleted by administrators and by users who have
the
[Delete Own Changes](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/access-control.html#category_delete_own_changes)
permission.

### Emails

#### HTML Emails

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`](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/config-gerrit.html#sendemail.html)
to `false`.

Users can opt to always receive plaintext emails by setting the
[Email Format preference](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/intro-user.html#email-format).

#### Closure Templates

Mail templates can now be written using
[Closure Templates (Soy)](https://developers.google.com/closure/templates/). Mail
templates written in Velocity (VTL) are deprecated but still supported. Support
for VTL will be dropped in the next release.

#### Review Comments by Email

Gerrit now supports
[receiving review comments by email](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/intro-user.html#reply-by-email).

### Secondary Index with Elastic Search

It is possible to enable Elastic Search as a secondary index by setting
[`index.type`](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/config-gerrit.html#index.type)
to `ELASTICSEARCH` and configuring the
[Elastic Search specific configuration parameters](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14/config-gerrit.html#elasticsearch).

Note that the Elastic Search implementation is still considered experimental
and it is not advised to use it for production systems.

### User Interface

* Tags can be created and deleted via the Tags screen in the UI.

### New User Interface ("PolyGerrit")

Gerrit now includes a new user interface, referred to as "PolyGerrit", based on
[Polymer](https://www.polymer-project.org/).

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.
