Ok, we'll use your phrase as the title. If someone suggests a better (more accurate and neutral) title, we can change it again. (Though that may have to wait overnight...)
The current title ("Sublime Text 3 is still in beta") sounds like an attack to me, implying slow development. I'd suggest "Sublime Text 3 marked as recommended build (Feb 2016)", or something like that. More wordy, but more accurate.
I certainly didn't intend any negative connotations to that sentence, but I agree in the context of the title it does give undue emphasis to 'still'. FWIW I use ST3 beta every day and it is an excellent text editor. I have no qualms about the development rate.
I think something like your title or even along the lines of 'Sublime Text 3 released [false alarm]' would work.
