Development builds for 2014-06-21 (Commit 190e3fdfab) can be downloaded from:
Two MAC builds – 10.6+ (QT4.8) and 10.7+ (Qt5.3)
Two Windows Builds – 32bit and 64bit. (Qt4.8.6)
This is the first 64bit build that I have released so will be interested in hearing if it all works.
Please provide feedback at the Google Groups link for this release.
