-* …
+* The C.UTF-8 locale should be used for $wgShellLocale, if available, to avoid
+ unexpected behavior when things use local-sensitive string comparisons. For
+ example, Scribunto considers "bar" < "Foo" in most locales since it ignores
+ case.
+* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
+ documentation of $wgShellLocale for details.
+* $wgJobClasses may now specify callback functions
+ as an alternative to plain class names.

+ over the instantiation of their jobs,
+ to allow for proper dependency injection.

+* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
+ specific tags to be added by users.
+* File storage backends that supports headers (eg. Swift) now store an
+ X-Content-Dimensions header for originals that contain the media's dimensions
+ as page ranges keyed by dimensions.
