[ANNOUNCE] Vala 0.7.9 - Compiler for the GObject type system

[Jürg Billeter <j bitron ch>]

We are pleased to announce version 0.7.9 of Vala, a compiler for the
GObject type system.

Vala 0.7.9 is now available for download at:
   http://download.gnome.org/sources/vala/0.7/

Changes since 0.7.8
 * Support array and string slicing.
 * Add --symbols commandline option.
 * Add avahi-gobject bindings (Sebastian Noack).
 * Add ccss-1 bindings (Ali Sabil).
 * Add libarchive bindings (Julian Andres Klode).
 * Add libmagic bindings (Jens Georg).
 * Add readline bindings (Jukka-Pekka Iivonen).
 * Add twitter-glib-1.0 bindings (Adrien Bustany).
 * Many bug fixes and binding updates.

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.

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. All that
is needed to use a library with Vala is an API file, containing the class
and method declarations in Vala syntax. Vala currently comes with
bindings for GLib and GTK+. It's planned to provide generated bindings for
the full GNOME Platform at a later stage.

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.
