Sublime's updates are dismal. https://www.sublimetext.com/blog/ I had to switch to Atom just because the development is stagnant. I liked Sublime very much. But it's been 2 years already..
The official download page says "Sublime Text 3 is currently in beta"
It's been like that for years. First build is from January 2013, it's almost 4 years already. I don't know what specifically is missing there, I just know I'm not comfortable using beta version (with little hope it will ever come out of beta) of a product for daily work. I see it as even developers don't consider it stable enough.
