Until the game is fully released, the boards will ignore version differences. Otherwise there would be many different unnecessary board splits, on the already thin boards. If you are interested in having a competitive time in any of the categories, simply use the newest version available.

Thor has already mentioned himself that if anything is found that does not damage casual game play in any way, he will leave it in to the benefit of the speedrunning community. This is very helpful down the road for when new patches or versions are released, as the boards should most likely remain in one piece.

When the game is fully released, all current categories will most likely be moved to a miscellaneous tab to exist as race categories or be removed entirely. Full game categories will then replace them as their own tabs.
