The development branch 1.1.1 release is ready now: http://icculus.org/news/news.php?id=3964
A lot of good progress in there.
Been working on yet-another-rewrite of this, in C, and it's largely workable
already, with both SDL and wxWidgets frontends: http://icculus.org/toby/
...all the heavy lifting is being done by a seriously mangled up Lua, which
saved me probably a year of work in this case.
Still more to be done on both of these, but they both feel really good right
now. Rock out.
