When I bought Sublime Text 2 if my memory serves me correctly I understood that ST 3 was a free upgrade, but ST 4 may be paid.
I have just downloaded ST 3 Beta to try it out and when I enter my licence is says that ST 3 is a paid upgrade from ST 2.
Your website still states the following:
"A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade." [sublimetext.com/sales_faq]
I wonder if you could clarify the situation of licence pricing to me, and whether there has been a change in which versions are free upgrades?
