	      strings.
	    - New examples 'hello-go' and 'hello-go-http' have been added.
	  * TypeScript:
	    - xgettext now supports TypeScript and TSX (= TypeScript with JSX
	      extensions).
	  * D:
	    - A new library libintl_d.a contains the runtime for using GNU gettext
	      message catalogs in the D programming language.
	    - xgettext now supports D.
	    - 'msgfmt -c' now verifies the syntax of translations of D format
	      strings.

	  * Modula-2:
	    - A new library libintl_m2.so contains the runtime for using GNU gettext
	      message catalogs in the Modula-2 programming language.

	      strings.

	# Improvements for maintainers:

	    'POT-Creation-Date' in the POT file is computed.
    0.24.1
	* Bug fixes:
	  - Fix bad interactions between autoreconf and autopoint.
	  - xgettext: Creating the POT file of a package under Git version control
	    is now faster. Also, the use of Git can be turned off by specifying
	    the option '--no-git'.
