The problem is the chronic lack of devs/testers in Windows, so unfortunately the releases for that OS are more prone to undetected bugs.
Most of the issues with 3.4.0 and 3.4.1 have been already fixed in the 3.5 development relase, so you could use a nightly build or learn to build DT yourself, it’s not difficult. Remember to alway make a backup of database before upgrading.
And if someone wants to help with testing of new releases, that’s more than welcome.
