+------------------
+
+Release Date
+^^^^^^^^^^^^
+
+- 2020-11-20
+
+
+New Features
+^^^^^^^^^^^^
+
+- Comments: introduced new draft comments.
+
+  * drafts are private to author
+  * not triggering any notifications
+  * sidebar doesn't display draft comments
+  * They are just placeholders for longer review.
+
+- Comments: when channelstream is enabled, comments are pushed live, so there's no
+  need to refresh page to see other participant comments.
+  New comments are marker in the sidebar.
+
+- Comments: multiple changes on comments navigation/display logic.
+
+  * toggle icon is smarter, open/hide windows according to actions. E.g commenting opens threads
+  * toggle are mor explicit
+  * possible to hide/show only single threads using the toggle icon.
+  * new UI for showing thread comments
+
+- Reviewers: new logic for author/commit-author rules.
+  It's not possible to define if author or commit author should be excluded, or always included in a review.
+- Reviewers: no reviewers would now allow a PR to be merged, unless review rules require some.
+  Use case is that pr can be created without review needed, maybe just for sharing, or CI checks
+- Pull requests: save permanently the state if sorting columns for pull-request grids.
+- Commit ranges: enable combined diff compare directly from range selector.
+
+
+General
+^^^^^^^
+
+- Authentication: enable custom names for auth plugins. It's possible to name the authentication
+  buttons now for SAML plugins.
+- Login: optimized UI for login/register/password reset windows.
+- Repo mapper: make it more resilient to errors, it's better it executes and skip certain
+  repositories, rather then crash whole mapper.
+- Markdown: improved styling, and fixed nl2br extensions to only do br on new elements not inline.
+- Pull requests: show pr version in the my-account and repo pr listing grids.
+- Archives: allowing to obtain archives without the commit short id in the name for
+  better automation of obtained artifacts.
+  New url flag called `?=with_hash=1` controls this
+- Error document: update info about stored exception retrieval.
+- Range diff: enable hovercards for commits in range-diff.
+
+
+Security
+^^^^^^^^
+
+
+
+Performance
+^^^^^^^^^^^
+
+- Improved logic of repo archive, now it's much faster to run archiver as VCSServer
+  communication was removed, and job is delegated to VCSServer itself.
+- Improved VCSServer startup times.
+- Notifications: skip double rendering just to generate email title/desc.
+  We'll re-use those now for better performance of creating notifications.
+- App: improve logging, and remove DB calls on app startup.
+
+
+Fixes
+^^^^^
+
+- Login/register: fixed header width problem on mobile devices
+- Exception tracker: don't fail on empty request in context of celery app for example.
+- Exceptions: improved reporting of unhandled vcsserver exceptions.
+- Sidebar: fixed refresh of TODOs url.
+- Remap-rescan: fixes #5636 initial rescan problem.
+- API: fixed SVN raw diff export. The API method was inconsistent, and used different logic.
+  Now it shares the same code as raw-diff from web-ui.
+
+
+Upgrade notes
+^^^^^^^^^^^^^
+
+- Scheduled feature release.
+  Please note that now the reviewers logic changed a bit, it's possible to create a pull request
+  Without any reviewers initially, and such pull request doesn't need to have an approval for merging.
