Hi all, Thanks for testing out first Release Candidate. We’ve fixed a number of issues (see below). Please consider the current master branch and snapshot binaries >= 2015.02.05 the second Release Candidate of OpenSCAD 2015.02. As usual, we’re planning to give it a week or so for testing before making a release, unless significant enough bugs or regressions surface, in which case the whole process will have to rinse and repeat until we’re content. Please give it a spin and pour your complaints here or on the github issue tracker.
