It depends on the answer 
For the moment, I would still stick to the statement that people should use openHAB 1. This is the version that is listed on www.openhab.org and for which there is documentation and support.
But I agree that we should start the discussion about what is still missing before we recommend openHAB 2 as the âmainâ distribution (and thus archiving the 1.x runtime, i.e. removing it from the homepage, making it a sub-category here in the forum (currently openHAB2 is the sub-category, etc.).
@rlkoshak Instead of describing in detail on how openHAB1 users can migrate to openHAB2 on the topic âSlider not working on 1.8.3â, this should really end up in the migration tutorial - this is for me a prerequisite, before we can declare 2.0 GA.
Wrt technical issues/features that are missing and that MUST be there for 2.0, I would suggest to track this on Github, probably best as a GA milestone on the distro, what do you think?
Btw, with what I wrote in here, I think that the overall stability and usability is pretty good now. There shouldnât be much missing for replacing a 1.8.3 runtime by a 2.0 runtime now.
