I know people who love Sublime but are worried about it disappearing, or paying for an upgrade only to see development to stall.

It's good to see that the Sublime team have responded to this with a licensing model that rewards them for releasing updates:

> Sublime Text license keys are no longer tied to a single major version, instead they are now valid for all updates within 3 years of purchase. After that, you will still have full access to every version of Sublime Text released within the 3 year window, but newer builds will required a license upgrade.
