We are trying to get back to a decent rythm. Last week, the team added the intersector between an infinite line and another infinite line so grips with those elements should be working.
We also corrected a few things in the Exporter system so you should now be able to save your drawings in the Archimedes file format (XML or ARC).
Finally, the trim system is being re-implemented to work with the new intersection system so the command is back though it does nothing.
Reminding everyone that odd versions (like 0.55) are unstable versions so you might find bugs. If you do, please report them as fast as you can so we can correct them for the next stable version.
