The current version in the repo is 1.4.0, which is almost 4 years old. The latest version, 1.6.0-rc, provided many fixes to games and is more stable over all. I have experienced issues in a few games with version 1.4.0, but are not present in 1.6.0-rc. Having the updated version in the repo will be fantastic and benefit us PS2 gamers. I would also like the note that the PCSX2 website still has the outdated release, the github is the best place to find the latest release.
