What exactly did dota2 rebirth beta do in steam?

Before the early DOTA2 used the reborn client,

You can optionally enter DOTA2 to regenerate the client.

Experience and help regenerate the customer's tests.

The reborn client not only changed the interface of DOTA2, but also changed the engine from Origin to Origin 2.

The early stage was very unstable (after all, the engine was changed instead of being done directly on Origin 2, which just went online), but it needs a lot of tests to improve slowly.

Therefore, using this method, I hope players can help me test and improve together.

When the DOTA2 rebirth is basically stable, V society directly replaces the official client with DOTA2 rebirth.
