Final

It's been a while but it is already here. Final version 2.0.0 of prusa_exporter. Version 1.0.0 was never released because it has got me into development hell and I was only circling around. I've scrapped almost everything but I was able to restart the development. That is actually the reason why I've called first restarted development version Omega instead of Alpha. As reference to Windows Vista, nothing was working, development stalled and I was deprived. Hopefully I was able to start again and here we are.

Unfortunately I've dropped support for Einsy boards (but you can use json_exporter for them) and SL1 printers. I'd like to integrate at least SL1 again but that is something that I do not know if it's gonna happen, I don't have big plans instead of one thing.

What now? I want to integrate exporter toolkit from Prometheus community and if they agree I'll transfer ownership of this exporter to them.

Thanks to everyone involved. @tomwilkie @RichiH @imax9000 @gouthamve @darnfish @matejgordon You are the best.

Enjoy. And Merry Christmas

What's Changed

Mostly fixing stuff in this release. Unfortunatelly printer type autodetection does not work reliably so it is strongly to not use this feature 😞.

• Docker compose for on-premise setup by @pstrobl96 in #92
• Updated docker compose image versions by @pstrobl96 in #93
