=== New user-facing features in 1.34 ===
* Special:Mute has been added as a quick way for users to block unwanted emails
from other users originating from Special:EmailUser.
+ * (T207577) Special:NewSection has been created as a shortcut to creating a new
+ section on a page. When linked to, its subpage is used as the target

+ the target manually.

+ to add fields to Special:Mute.
