Site admins can now force a specific user to re-authenticate on their next request or visit.

To define repository groups (search.repositoryGroups in global, org, or user settings), you can now specify regular expressions in addition to single repository names.

Files and directories can now be excluded from search by adding the file .sourcegraph/ignore to the root directory of a repository.

Structural search syntax now allows regular expressions in patterns. Also, ... can now be used in place of :[_].

Experimental: A new homepage UI for Sourcegraph Server shows the user their recent searches, repositories, files, and saved searches. It can be enabled with experimentalFeatures.showEnterpriseHomePanels.

Campaigns are enabled by default for all users. Site admins may view and create campaigns; everyone else may only view campaigns.

Negated content search is now also supported for unindexed repositories. Previously it was only supported for indexed repositories.

rev: is available as alternative syntax of @ for searching revisions instead of the default branch

Sourcegraph now watches its configuration files (when using external files) and automatically applies the changes to Sourcegraph's configuration when they change. For example, this allows Sourcegraph to detect when a Kubernetes ConfigMap changes.
