The Dota 2 engine branch was the first Source 2 engine branch to be released, first introduced with Dota 2 Reborn update in 2015, which also makes Dota 2 the first game to use Source 2.

The Dota 2 branch (pre-Reborn) originally introduced in 2013 with the release of Dota 2, used to be the latest Source branch available, succeeding the Counter-Strike: Global Offensive engine branch, starting with Reborn update released in 2015, the game was upgraded to the then-new Source 2 engine, which makes CS:GO the latest Source 1 branch available. Additionally, this is the only Source 1 engine branch that was never licensed to third-party developers.
