To join the f.lux beta...

  • f.lux team

    If you want to help out and test beta versions of f.lux, you should do these things:

    • go to "About f.lux" in v4, and opt in to beta releases
    • restart f.lux to make it notice the update and give you the beta version right away

    If you want to leave the beta in the future:

    • Uncheck the box in "About f.lux" (or uninstall if f.lux isn't usable)
    • Download again from the website:

  • I just got the new version (v4.69) pushed: looking good! I haven't had a chance to try it out yet but the options look like just what I personally needed. Have you ever considered making f.lux open source to lighten your workload?
