+:image_credit: Reviewing build output for a project in our new dashboard
+
+For the last year, you may have seen notifications and hints asking you to try
+out our new dashboard. This new dashboard has been a long term project to
+completely replace our original user interface with one that is more
+consistent and allows us to more easily build and maintain complex features.
+
+During the next few months, we will begin the transition to our new dashboard
+and will move away from our current, *but soon to be legacy*, dashboard.
+
+If you are not yet using our new dashboard, here is what you need to know:
+
+The new dashboard will start to become the default dashboard
+    After this change, users logging in from our website will be logging into
+    our new dashboard. *Users will still be able to switch back to the legacy
+    dashboard if they need to*.
+
+    - On `Read the Docs Community`_ this change will go into effect on **Nov 12th**
+    - On `Read the Docs Business`_ this change will go into effect on **Dec 10th**
+     
+    To log in to the new dashboard:
+
+    - Users of `Read the Docs Community`_ can log in at https://app.readthedocs.org/account/login
+    - Users of `Read the Docs Business`_ can log in at https://app.readthedocs.com/account/login
+
+The legacy dashboard will be available until Mar 11th, 2025
+    Our legacy dashboard will remain available while users are transitioning to
+    our new dashboard. During this period, our legacy dashboard will no longer
+    be receiving updates or new features, but it will remain active. Our legacy
+    dashboard will only be available for this limited period, after which it
+    will be shut down for all users.
+
+    To log in to the legacy dashboard:
+
+    - Users of `Read the Docs Community`_ can log in at https://readthedocs.org/account/login
+    - Users of `Read the Docs Business`_ can log in at https://readthedocs.com/account/login
+
+
+How is the new dashboard different?
+-----------------------------------
+
+You should find that the new dashboard is more consistent and that navigation
+around the dashboard is easier overall. New features were added for sorting and
+filtering, build output is easier to browser and share, and project and version
+creation is more intuitive.
+
+The new dashboard contains many other updates and new features as well. In the
+coming weeks we will be highlighting in more detail what new features were
+added, interfaces that have been updated, and some of the technical changes
+introduced.
+
+Documentation page changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Rollout of our new dashboard will also be apparent on hosted documentation.
+There are several pages in hosted documentation where our own dashboard is
+visible to readers:
+
+Documentation error pages
+    We display an error page to readers when we encounter a problem with their
+    request, like when a requested file is missing (HTTP 404 error).
+
+    We do not show our error page when a custom 404 error page is provided by a
+    project.
+
+Authentication forms
+    This includes documentation authentication pages, such as password and
+    GitHub authentication, and documentation sharing pages, such as sharing
+    password entry.
+
+On **Dec 10th**, projects hosted on `Read the Docs Business`_ will
+use our new dashboard for these pages in their hosted documentation.
+
+*There will be no changes to user generated documentation otherwise.*
+
+If you would like to update your project to use these pages before then,
+`contact us`_.
