There are some fixes; including a missing translate tag that caused an item to not be shown in the translate interface.
The new VE options to set the display title is more descriptive (and adds the precision that it only works on wikis that authorize this change, e.g. DISPLAYTITLE is disabled and produces no effect on Meta-Wiki, some wikis are restricting the change to only names that are canonically equivalent to the pagename, after conversion of underscores to spaces and conversion of the first character to uppercase; some wikis are more permissive and allow arbitrary changes but on most Wikimedia wikis, this setting is restricted, if not simply disabled)
Most wikis do not need the __AMBIG__ magic keyword (they integrate it in the code of a message box template, which should be inserted at top or bottom of pages (the placement of this box is dependant of common practices for each wiki. The name of the message template is also wiki-dependant. I don't know if the VisualEditor is customizable on each wiki to specify which code shokd be used to call the template instead of the magic keyword.
