This release is mainly a bugfix release that solves several old issues. It is also now correctly synchronized with all the current bindings done for Red/System. The main changes are:

• Internal compiler refactoring of: expressions compilation, type casting and ANY/ALL support.
• Greatly improved runtime error reporting: now it reports both source line number and source file name where the error occured. It works in debug mode only (-g command-line option).
• Aliased struct names can now be tested separately in typed (RTTI) functions.
• Callback function attribute removed. It is no more needed and any function can now be used as a callback. In addition a new cdecl attribute is now accepted to allow the switch to C calling convention, when passing a function as argument to an imported C function.
• 21 issue reports closed.
• More than 2000 new unit tests were added (mostly generated using scripts wrote by Peter WA Wood) for a total of now 8613 tests.

I have been invited at the Software Freedom Day 2011 (September 14th) to give a talk about Red. Here are the presentation slides and the video.

If you are experiencing issues seeing the slides in flash format, here’s a PDF version.

I am not a great speaker, so you might want to go through the slides first, and eventually have a look at my corresponding comments in the video (it is too long anyway). I need to make shorter and faster presentations in the future.
