Woopsi 0.99.5 is now out. It is available from the Woopsi website:

http://woopsi.org

The big change this time around is the rendering system. Instead of each gadget needing to redraw itself when its appearance changes, gadgets now push their damaged rectangles to a queue that is redrawn every VBL.

In short - redrawing the screen is faster and the code is simpler.

The FreeType library and associated classes are no longer being distributed as part of Woopsi. Instead, Lakedaemon has put together a distribution of Woopsi that includes ported libraries and extra classes. These provide Woopsi with a wealth of extra functionality. His distribution can be found here:

http://bitbucket.org/Lakedaemon/ndstoolkit/overview

On top of the FreeType library, Woopsi font classes and an "XmlBox" gadget, it includes DS ports of:

- libjpeg
- libmxml
- libpng
- libsqlite3
- libz

The full changelog is below.
