There's never a mandate to upgrade, but the latest is always available for a test drive, to check out new features.
Good to hear that the latest solved the issues. If it is beyond the six-month window, which seems a reasonable policy, search the repository as suggested above for a later release that's within the period. The problem may have been fixed.
Unlike some NLEs, VP is enhanced often. Though it's tested, glitches can creep in. Should a problem crop up, outline it here and someone will try to replicate it. It could be a setting or editing issue. If a true bug is confirmed, it will be quickly addressed.
