Over the next few days, 1.26wmf22 will be deployed to WMF wiks. We have a number of exciting new things coming in this deployment:

• The notifications flyout at the top right of every page has been split into two flyouts. Notifications from Flow pages and from your user talk page are put in the "messages" flyout, whereas other notifications are put in the "alerts" flyout. This change was also announced earlier on the Wikitech Ambassadors list and on Tech News. Please give us feedback on this change on the Echo talk page.
  
• Topic headers in Flow are now less tall and use a smaller font. The mark as resolved (check mark) icon in these headers is now better aligned and is correctly positioned in right-to-left languages.
• The warning shown when posting as an anonymous user has been redesigned.
• When writing or editing posts, the cancel button now actually deletes the text you wrote, and warns you before doing so.
• Editing existing Flow posts now uses the new editor system introduced in wmf19.
• The Topic namespace is now translated in Arabic.

wmf22 will be rolled out according to the standard deployment schedule:
