Here is a summary of DWScript changes since the last update.
Language enhancement are centered around several additions for enumeration elements and sets, as well as a standard Map() method for arrays. The JIT compiler also got more capable, and there were various improvements to the support libraries and compatibility with older (D2009) and newer (DXE3) Delphi versions.

A couple days ago, a Pascal game compiled with SmartMobileStudio was accepted on the FireFox MarketPlace as a packaged app.
It had only been tested on the FireFox OS desktop simulator, how would it hold its own on a real device?
We’re not talking of flagship phones with quad-cores like a Galaxy, a Nexus 4 or an iPhone, but mainstream, single-core, sub-$100 hardware…
For a couple months now, a JIT compiler has been available in the DWScript SVN for 32bits code. The JIT is meant to be transparent, that is, execution, debugging facilities and memory layouts are similar under JIT and interpretation, the only difference is the performance.
The JIT also uses a hybrid architecture, which was designed to allow developing the JIT incrementally, which directly derives from my only working on it a few hours at a time, every once in a while.

Here is a summary of recent changes, language highlights are initial support for sets and a new Sort() method for dynamic arrays.
Apart form Linq & LLVM libraries which were previously mentioned, Brian Frost made multiple updates to the IDE Dialog. There were numerous other minor fixes and improvements, related to stability, performance and compatibility with Delphi code.

Graphics32 is a rich, high-performance 32bits graphics library for Delphi, with extensive capability. This showcase was submitted by Christian-W Budde, who is an active contributor to the Graphics32 project.
Very experimental support for LLVM in DWScript is now in the googlecode repository, thanks to the efforts of Christian-W Budde.
This is the beginning of the opening of new realms of possibilities for DWS!
LLVM support is currently centered around jit compilation, and at the moment doesn’t extend much beyond the needs of the Mandelbrot demo (see below for what is supported right now).
Here are the main DWS news items for May 2012

Visual Basic in its various incarnations and off-springs has super-powers when it comes to OLE Automation, aka late-bound COM through IDispatch.
Where do they come from?
For a few weeks now, an experimental JIT compiler has been available in the DWScript SVN for 32bits code. A more detailed article into the hows and whats and WTFs will come later.
Consider this article as an extended teaser, and a sort of call for test cases, benchmarks and eyeballs on the source code.

Answering the call for showcases, Steffen Binas prepared a very nice set of screenshots for AquaSoft‘s Slide Show impressive product, which went far beyond the minimal requirement, so I’m posting a full-blown article about it. Following is the presentation of their software and how DWScript is used inside it.
When you need a powerful showcase I’d bet AquaSoft SlideShow is the one: http://www.aquasoft.de/diashow
Despite the simple name of the application it’s very powerful, just have look at the trailer video created completely with it.
