+## Percona Platform Portal powered by MUI
+When you [sign into Percona Platform](https://portal.percona.com), you'll see that the general look-and-feel is slightly different.
+
+This is the result of what we've been working on lately. We stopped using the Grafana UI library and migrated over to MUI (Material UI).
+
+This is only the first phase of a more ambitious initiative, led by our amazing Design team, which involves overhauling the general user experience for Percona Platform Portal.
+
+During this first phase we focused on migrating over to the new UI library, while the next phase will bring redesign elements (i.e. better UX).
+
+This change gives us a much better foundation to continue building and growing the Percona Platform Portal on.

+## Improved handling of invalid account activation links
+
+We're now showing a more meaningful message for attempts to activate a Percona Account from a link that contains an expired token.
