Look at the "last modified" dates at the bottom of the pages on that site. I'm pretty sure you're looking at the very old pre-open-source version of the site from the previous developer.

The download section links to 2.0 beta 10, which I assumed to be the one in TFA.

I actually cant find these last modified dates you refer to. The footer just display this for me:

    MacroMates Ltd. — Cyprus — HE 259033 — VAT CY-10259033P

Mea culpa, looks like it's only on the wiki pages: Page last modified on July 27, 2011, at 08:56 UTC

That, and the blog that was last updated four years ago.

Previous developer? Was there a change? Isn't it still developed by Allan Odgaard?

(I'd love to read the story of TextMate)

Hmm, now that I look it up, I guess he is still involved. Like I can be bothered to care, as 2.0 was announced in 2009 as 90% complete. Nine years later, there's still no release version. I've moved on, and I imagine a large portion of the user base has done the same. I kinda forgot Textmate even existed until this popped up this morning.
