>>106172345>or is the very last version the best, for creating new flashes?Any of the latter ones if you want to be sure you're covered
The introduction of ActionScript 3.0 was obviously a massive leap forward in regards to programming for flash, but with each of Adobe's updates came more bloat and lag to the IDE. Some creators swear by classic Macromedia era flash due to reliability, it's quicker to crack and 99.9% of the basic shit anybody uses was already there. From the Adobe ones CS3 and CS5.5 are the versions I hear people talk about the most but it's really up to preference.
