We're working hard on preparing the first update to TextMate in form of version 1.0.1. If the anticipation is too much to bear, you can come live on the edge with TextMate betas. Roughly one will be released per day, so you should be fit too keep up.
To activate beta notifications, close TextMate, start terminal, paste
defaults write com.macromates.textmate OakCheckForBetaVersions 1. You'll get the requester on first startup.
Beware that betas will contain new and untested features. There will most certainly be bugs from time to time.
