[Vala] [ANNOUNCE] Vala 0.2.0 - Compiler for the GObject type system

We are pleased to announce version 0.2.0 of Vala, a compiler for the
GObject type system.

Vala 0.2.0 is now available for download at:

Changes since 0.1.7
 * Support nested namespaces.
 * Support static constructors.
 * Register enums with GType (Marc-André Lureau)
 * Small syntax change for default values of properties.
 * Add --verbose commandline option (Daniel Silverstone)
 * Improve pointer support.
 * Add GNOME Keyring bindings (Andrea Del Signore)
 * Add SDL bindings (Levi Bard)
 * Add libftdi bindings (Evan Nemerson)
 * Updates to the GLib, GTK+, GStreamer, and SQLite bindings.
 * Many bug fixes all over the place.

Vala is a new 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. It's also planned to generate GIDL files when gobject-
introspection is ready.

The syntax of Vala is similar to C#, modified to better fit the GObject
type system. Vala supports modern language features as the following:

        * Interfaces
        * Properties
        * Signals
        * Foreach
        * Lambda expressions
        * Type inference for local variables
        * Generics
        * Non-null types
        * Assisted memory management
        * Exception handling

Vala is designed to allow access to existing C libraries, especially
GObject-based libraries, without the need for runtime bindings. Each to
be used library requires a Vala API file at compile-time, containing the
class and method declarations in Vala syntax. Vala currently comes with
bindings for current versions of GLib, GTK+, and many more.

Using classes and methods written in Vala from an application written in
C is not difficult. The Vala library only has to install the generated
header files and C applications may then access the GObject-based API of
the Vala library as usual. It should also be easily possible to write a
bindings generator for access to Vala libraries from applications
written in e.g. C# as the Vala parser is written as a library, so that
all compile-time information is available when generating a binding.
