It's not in the beta stage yet. There will be beta's and then release candidates. My guess is between one and three months.

If you use the dev snapshot and find and report bugs, that should help reduce the time. I've been using 4.3 since December, and it seems stable to me.

    DaveTheCoder I had an annoying issue with 4.3, but I forgot what it was. 🙁
    Couldn't have been that annoying if I already forgot what is was...will use 4.3 again. 😃

      a month later

      evanchoquene125 I think it will take a while for Godot 4.3 to get out of the Beta and RC stage
      because there's so many new features added and right now, it crashes a lot (compared to 4.2 beta releases)

          Just checkout git, compile the development build, live on the edge.

          I changed the tags as this felt like it was more meant for Godot in general. But let me know if this was meant to be The Mirror related and I'll switch it back.
