Four public builds are on the release list. The newest is v0.2.0-beta from 2 November 2026, protocol 164. Same protocol means the download page will let those players share a session. A newer protocol does not speak to an older one.

Release records checked 4 November 2026. October builds with one archive have no separate 2.31 file record; blank cells are intentional.

What 0.2.0 changed

  • The open world no longer waits on the party, and fixer gigs are shared.
  • Some boss fights allow several players, and boss health grows with the team.
  • Mods a partner lacks fall back to vanilla cars, weapons, weather, and radio.
  • An SDK for mod authors, MIT, with C, redscript, and CET.
  • Fixes named in the notes: story sync, NPC sync, T-poses, saves that were hidden or deleted, crashes, and a freeze.

0.1.2-beta, on 27 October, added translations for all 19 game languages, a co-op photo mode that leaves the world running, a mod check when joining, voting, and shared quest tracking. It also lists better sync for story, phone, braindance, and skipping cutscenes. 0.1.0-beta.1 on 23 October was the first open beta: story together, your own V, shared fights, and a hub restart that does not end the session. File sizes and full hashes are on the download page. The current project release list is the source for dates and protocol numbers.

Questions

Which builds can play together?

The download page says the same protocol. 164 is 0.2.0 only. 143 is 0.1.2 only. 128 is shared by 0.1.0-beta.1 and 0.1.1-beta.2.

Which builds are included in the independent security analysis?

The analysis names 0.1.0-beta.1 and 0.1.1-beta.2. It does not cover 0.1.2-beta or 0.2.0-beta; use the release table to keep that scope separate from the current download.
