-       * Fixes:
-         - Spurious spaces when autoloading locales (bug introduced
-           in 3.46 when fixing #80).
-         - In dtx files, autoloading printed some spurious text
-           (because % is set to ignore, #87).
-       * New - \getlocaleproperty*, which doesn't raise an error.
-       * Basic ini+tex templates for about 500 languages in the GitHub
-         repository.

-       * Languages can now be optionally selected with their BCP 47
-         tags.
-       * \BabelEnsureInfo now loads the basic data for the requested
-         languages immediately (formerly it was done at the end of the
-         preamble).
-       * Fixes:
-         - Getting rid of the hyphen in XeTeX was not working as
-           expected. A new procedure has been devised.
-         - tag.bcp47 now contains what its name promises, instead of
-           just the language subtag (#70).
-         - Locale info was not loaded if the name had uppercase letters
-           in some OSs (#80).
-         - The [..|..] syntax in ini dates didn't recognize 'digits'.
