I released 0.34.0 last week and a number of people found defects. One defect in particular (where the cursor would disappear on Linux systems) was major enough to warrant a new release. I've released 0.34.1 with that defect fixed along with a couple others. Changes between 0.34.0 and 0.34.1 are:
I apologize to anyone that was frustrated by these defects after upgrading to 0.34.0. It seems the unstable update site isn't being tested as much as I'd hoped. I may have to introduce some concept of a 'release candidate update site' which isn't updated as often as unstable but provides our users who don't want an "unstable" build to play with new builds before I declare them "stable".
