I watched some videos on YouTube recently featuring Counter Strike: Condition Zero, but I'm not sure which shows the latest version of the game.
There's no major differences between them, but bot/weapon skins and sound effects have minor differences, but not in a way that someone could tell one was newer over another.
All are shown as 'Condition Zero' and have same Tour of Duties and UI/UX.

Game 2 is standard Counter Strike (latest version 1.6).
Game 1 and 3 are the same, which is Counter Strike :Condition Zero.
You can tell the difference by a couple of things.
First, on game 3, the name is clearly indicated on the score screenshot. Game 3 and 1 shares the same updated player models for the red bandana terrorist.
You can differentiate 1.6 from CZ by the little location written under the minimap.
And to answer your question, Condition Zero is the most recent of the two. CS is 2000 while CZ is 2004.
