What problem are we solving here?

[kLabz]

The linked issue, though a more general solution for the "does current haxe support X?" problem would be more convenient

[Simn]

wtf are linked issues... ok I see

I think we had this discussion before, but I generally don't want people to discriminate against preview versions and release candidates. That's one of the few things that distinguishes them from proper releases where we want to ensure a certain amount of backwards compatibility. We reserve the right to break anything between a preview version and a proper release, so users should be aware of that.

IMO the best solution is to just release preview.2 soon and tell everyone to update.

Makes sense; though I half expect them to just run haxe --version to grab the actual version instead, which is a bit silly 😅

Probably yeah, but we can just say that this voids their warranty!
