+## Unreleased
+
+### Added
+
+- Endpoint environment variables (`SEARCHER_URL`, `SYMBOLS_URL`, `INDEXED_SEARCH_SERVERS`, `SRC_GIT_SERVERS`) now can be set to replica count values in Kubernetes, Kustomize, Helm and Docker Compose environments. This avoids the need to use service discovery or generating the respective list of addresses in those environments. [#45862](https://github.com/sourcegraph/sourcegraph/pull/45862)
+- The default author and email for changesets will now be pulled from user account details when possible. [#46385](https://github.com/sourcegraph/sourcegraph/pull/46385)
+- Code Insights has a new display option: "Max number of series points to display". This setting controls the number of data points you see per series on an insight. [#46653](https://github.com/sourcegraph/sourcegraph/pull/46653)
+- Added out-of-band migration that will migrate all existing data from LSIF to SCIP (see additional [migration documentation](https://docs.sourcegraph.com/admin/how-to/lsif_scip_migration)). [#45106](https://github.com/sourcegraph/sourcegraph/pull/45106)
+- Code Insights has a new search-powered repositories field that allows you to select repositories with Sourcegraph search syntax. [#45687](https://github.com/sourcegraph/sourcegraph/pull/45687)
+- You can now export all data for a Code Insight from the card menu or the standalone page. [#46795](https://github.com/sourcegraph/sourcegraph/pull/46795), [#46694](https://github.com/sourcegraph/sourcegraph/pull/46694)
+- Added Gerrit as an officially supported code host with permissions syncing. [#46763](https://github.com/sourcegraph/sourcegraph/pull/46763)
+- Markdown files now support `<picture>` and `<video>` elements in the rendered view. [#47074](https://github.com/sourcegraph/sourcegraph/pull/47074)
+- Batch Changes: Log outputs from execution steps are now paginated in the web interface. [#46335](https://github.com/sourcegraph/sourcegraph/pull/46335)
+
+### Changed
+
+- Code Insights has a new UI for the "Add or remove insights" view, which now allows you to search code insights by series label in addition to insight title. [#46538](https://github.com/sourcegraph/sourcegraph/pull/46538)
+- When SMTP is configured, users created by site admins via the "Create user" page will no longer have their email verified by default - users must verify their emails by using the "Set password" link they get sent, or have their emails verified by a site admin via the "Emails" tab in user settings or the `setUserEmailVerified` mutation. The `createUser` mutation retains the old behaviour of automatically marking emails as verified. To learn more, refer to the [SMTP and email delivery](https://docs.sourcegraph.com/admin/config/email) documentation. [#46187](https://github.com/sourcegraph/sourcegraph/pull/46187)
+- Connection checks for code host connections have been changed to talk to code host APIs directly via HTTP instead of doing DNS lookup and TCP dial. That makes them more resistant in environments where proxies are used. [#46918](https://github.com/sourcegraph/sourcegraph/pull/46918)
+- Expiration of licenses is now handled differently. When a license is expired promotion to site-admin is disabled, license-specific features are disabled (exceptions being SSO & permission syncing), grace period has been replaced with a 7-day-before-expiration warning. [#47251](https://github.com/sourcegraph/sourcegraph/pull/47251)
+
+### Fixed
+
+- Fixed a bug where saving default Sort & Limit filters in Code Insights did not persist [#46653](https://github.com/sourcegraph/sourcegraph/pull/46653)
+- Restored the old syntax for `repo:contains` filters that was previously removed in version 4.0.0. For now, both the old and new syntaxes are supported to allow for smooth upgrades. Users are encouraged to switch to the new syntax, since the old one may still be removed in a future version.
+- Fixed a bug where removing an auth provider would render a user's Account Security page inaccessible if they still had an external account associated with the removed auth provider. [#47092](https://github.com/sourcegraph/sourcegraph/pull/47092)
+- Fixed a bug where the `repo:has.description()` parameter now correctly shows description of a repository synced from a Bitbucket server code host connection, while previously it used to show the repository name instead [#46752](https://github.com/sourcegraph/sourcegraph/pull/46752)
+
+### Removed
+
+- The Code insights "run over all repositories" mode has been replaced with search-powered repositories filed syntax. [#45687](https://github.com/sourcegraph/sourcegraph/pull/45687)
+
