+## `\localeinfo*`
+
+Sometimes, it comes in handy to be able to use `\localeinfo` in an
+expandable way even if something went wrong (for example, the locale
+currently active is undefined). For these cases, `localeinfo*` just
+returns an empty string instead of raising an error. Bear in mind that
+`babel`, following the CLDR, may leave the region unset, which means
+`\getlanguageproperty*` (see the manual) is the preferred command, so
+that the existence of a field can be checked before. This also means
+building a string with the language and the region with
+`\localeinfo*{language.tab.bcp47}-\localeinfo*{region.tab.bcp47}` is
+not usually a good idea (because of the hyphen).

 ## Fixes
 
 * Misplaced line in `diagbox` with RTL and `luatex` (#43)
 * Caption names of ‘chapter’ and ‘part’ swapped in the `ini` files for
   Traditional Chinese (#180).
 * Captions are now placed after numbers in the `ini` file for Lithuanian.
+* The `hyphenrules` in `en-AU` and `en-NZ` were set to `english`
+  instead of `ukenglish`.
 
 ## Script ranges
 
 The Unicode character ranges were hard-coded in the `babel` kernel, but
 now they can be set or modified in the `ini` with the key `ranges` in
 the `characters` section (as well as in `\babelprovide`). A few

 Note you cannot define different blocks for different languages sharing
 the script. If there are multiple declarations, the last one wins.
