I know this could be easily googled, but in the spirit of posting, generating traffic, etc. I'll post it here.

If you are strictly a quest player, like myself (even though I don't think I've ever completed a single quest), do older quests typically have to be "updated" to work with this version? Does that cause bugs sometimes?

Should anything prior to 1.92 184 only be played with that player? Anything since then only be played with this one? Or with beta created with?

Will 2.5 complete be able to play ANY quest correctly, or just quests made after 1.92 184? Or is that unknown?

Basically, am I going to have to have 50 versions of ZC to cover a wide timeline of quests?

Shed some light.
