Version 2 of Sublime Text was initially released in 2011 and last release was in July 2013. Still it’s the main version! Version 3 last release was in March 2015 — and it’s still in beta and hasn’t gotten an update for 10 months. Don’t get me wrong, Sublime is awesome, but it’s not under active development. Atom is very active and has been from the start, Sublime is not. Atom is also open-source, Sublime is not.
However, this is about my Atom setup, not a rant about why Atom is better than Sublime.
