 MQL uses a set of operations and functions. Operations are linked together using the common pipe mechanism, where the output of one operation becomes the input to the next. Linking operations makes it possible to build up complex queries incrementally.

 ### New audit log events
 
-New log out events are logged based on when a token expires or is revoked, as well as [SAML Single Logout]({{< relref "../enterprise/saml.md#single-logout" >}}). A `tokenId` field was added to all audit logs to help understand which session was logged out of. [Auditing]({{< relref "../enterprise/auditing.md" >}}) was updated to reflect these changes.

 ### Reports support Unicode
 
 You can now select a font, other than the default, for Unicode-based scripts. As a result, an automatically generated PDF of a dashboard, which contains for example Chinese or Cyrillic text, can display them. Because the size of a report increases as additional fonts are added, this feature is not on by default.

 ### Plugin compatibility
 
 We have upgraded AngularJS from version 1.6.6 to 1.8.2. Due to this upgrade some old angular plugins might stop working and will require a small update. This is due to the deprecation and removal of pre-assigned bindings. So if your custom angular controllers expect component bindings in the controller constructor you need to move this code to an $onInit function. For more details on how to migrate AngularJS code open the migration guide and search for pre-assigning bindings.
