[ANNOUNCE] Vala 0.21.1 - Compiler for the GObject type system

[Jürg Billeter <j bitron ch>]

We are pleased to announce version 0.21.1 of Vala, a compiler for the
GObject type system.

Vala 0.21.1 is now available for download at:
   http://download.gnome.org/sources/vala/0.21/

Changes since 0.20.1
 * Support \uXXXX escape sequences.
 * Support specifying vfunc order in interfaces to define ABI.
 * Support GTK+ widget templates.
 * Bug fixes and binding updates.

Vala is a programming language that aims to bring modern programming
language features to GNOME developers without imposing any additional
runtime requirements and without using a different ABI compared to
applications and libraries written in C.

valac, the Vala compiler, is a self-hosting compiler that translates
Vala source code into C source and header files. It uses the GObject
type system to create classes and interfaces declared in the Vala source
code.
