It wasn't the longest beta, though we did get set back twice during the cycle. It just seemed longer because someone (rick) blabbed (josh) part of the 6.4 list during the 6.3 beta.

No biggy. I bought a tube of superglue, a hammer, and some nails

Seriously though, I know 6.3 added a lot of things most of you don't care about, but it served some real purposes. It gave .threads a better chance to easily broaden it's appeal into new markets. It laid a good foundation to redo that control panel into something bigger and more easy to use (find stuff). It fixed the mass email problems and made .threads a more viable tool to use for site owners to communicate with users. It added more polish to .threads too. Next time you have a user with a cookie problem point them to the remove cookie link in the FAQ. How much time will that save some of you?
But, again, I know some of you don't care about that at all. Which is why I didn't mind part of 6.4's list going out even in the middle of 6.3. To give those of you that don't care about setting your charset something to look forward to. We didn't forget about you.
