About vala
==========

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, Type modules
(Plugins)

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+ and many others from the GNOME
Platform.

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.

News
====

 * Various improvements and bug fixes:
  - codegen:
    + Correctly handle chain up of struct creation methods [#1264]
    + Use a dedicated EmitContext for _variant_get*() functions
    + gtkmodule: Handle nested closure elements and bind them accordingly [#1262]
  - vala:
    + NullLiteral is not a valid argument for string concatenation [#1260]
    + Set is_yield_expression in async context when chaining up to async base ctor
    + Report statement parsing error if it is not meant to be an expression [#1261]
    + girparser: Avoid possibily creating duplicated attributes
  - vapigen.m4: use $PKG_CONFIG_SYSROOT_DIR

 * Bindings:
  - glib-2.0: Always use the actual C type for CCode.array_length_type
  - gstreamer: Cherry-pick bindings fixes from 0.56
  - gstreamer-1.0: Unskip the ElementFactory.make/create_full() symbols
