+* The API will now warn if input is not NFC-normalized Unicode or if it
+ contains invalid characters.
+* The 'normalized' list output by action=query and other modules that use
+ ApiPageSet may contain entries where the 'from' value is percent-encoded as
+ the raw value cannot be represented in a valid API response. These are
+ indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
+* (T28680) action=paraminfo can now return info about all submodules of a
+ module without listing them all explicitly.
