 ## [Unreleased][]
 
-### Changed
+No changes so far
 
-### Added
+## [9.0.0][] - 2019-02-25
+
+Breaking change: messages of type `announcement` no longer have any effect.
+`/features` no longer routed.
+
+Via [uPortal-app-framework 12.0.0][]:
+
+* Tells IE users about recommended browsers during bootstrapping.
+* `list-of-links` widget appears more consistent across browsers and screen
+  sizes
+* `action-items` widget degrades to basic widget when configured with just one
+  indicator and that one indicator is failing.
+
+### Removed
+
+* `/features` route (#871) and, by adopting uPortal-app-framework 12, removed
+  mascot "announcements" more generally.
 
 ### Fixed
 
 * Removed rate app button from `exclusive` and `static` templates #868
+* Removed references to ratings from marketplace pages. #870
 * Changed label on UI control for switching home page between expanded and
   compact widget modes, to make this feature more recognizable to and
   understandable by users. New label is "Change tile size"; was
   "Toggle expanded widgets". Also updates the associated `aria-label`. #866
-* Removed references to ratings from marketplace pages. #870
-
-### Deprecated
+* Removed watch configuration from `cssVars`, because it made loading slow in
+  IE11. Delays init by one second, because trying to run it directly after the
+  bootstrapping is too early for IE on the first render. #872
