As others have pointed out, the 6.2 release is a tiny bug fix, and even 6.1 is a modest update since LT went open source.
The real story about Light Table since then is the growth of available plugins. Most look like early efforts, but the promise is there. There are early plugins for F#, Ruby, OCaml, Haskell, and others. There's even a plugin to play othello in the editor. https://github.com/eriksvedang/othello/
Light Table and its plugins are written in ClojureScript which is compiled to JavaScript. Source maps allow you to pleasantly debug the original ClojureScript instead of the generated JS.
Any idea if there's a plugin for evaling pre-processed languages like Haml, Sass or CoffeeScript?
And is there a good place to find a list of plugins? I've tried googling for them but I feel like there are probably plugins I'd use that I wouldn't think to google for.
Looks like a substantial number of upvoters didn't read TFA at all [1]. I wonder what the front page would look like if only upvotes that happened after clicking the link would be counted.
[1]: Or they are all LT users with light themes. Don't really believe that though.
