As suggested I've upgraded to 2-0 to keep compatibility with my new Mavericks OSX system.

I've noticed some changes, in fact some missing features I found useful on previous textmate's versions:

1. no more transparency 

2. when coding in Python, indentation is no more cancelled when typing ":" (I explain: when introducing an if statement, you type if test: then after the return your code is automatically indented, that's normal but when you type else: the ":" is expected to cancel the indentation of the else so it is well aligned with the if... that was the behavior of the previous versions)

Do I miss some configuration or is it a known bug?

Thanks for answers,
