Lume v2.1.1 is out with few improvements and bug fixes, settings screen is fully worked now. This time you can use auto-updater to update to new version, it is fully working fine now.

Since I've sold my Windows machine, I'm cannot do some test for Windows and Linux, but I will trying test it in VM.

I'm commit this week for bug fixes and stability update only, after that I will move to add new features to Lume.
