So my license expired, the last version I have access to is 1.4.5...Is 1.5 that much of a change? I intended on buying the extension, but I read the change logs up to 1.5 and outside of security fixes, I didn't really see anything compelling feature-wise and I never experienced any of those bugs mentioned while running my board before. Am I missing something, or can I stay at 1.4.5? What about addon devs, support for 1.4 still? Thanks, been away from XF for over a year now.
