Well, Ipe 6.0pre30 has just been released yesterday. From the announcement email, the major features of this release include:
* Ipe now works with pdftex 1.40 (in MikTeX 2.6 and texlive 2007).
* Pascal-Nicolas Becker, Frederik Hermans, and Damian Schmidt
implemented the missing forms of intersection snapping (for arcs
and Bezier curves), with bug fix by Jonathan Backer.
* Fixed the broken user interface (fields were too small to contain
the text) on Unix (removed a static QFont) (bug #191).
* Figtoipe now distributed separately.
I note that the source and the windows packages are already available at the LuaForge download site.
