Dear Sir/Madam,
Forgive me for this unsolicited (one time) service announcement.
I am writing because you have a TextMate license. If you wish to update to OS X 10.9 (Mavericks) and are still using TextMate 1.x then you should be aware that some bundle items will fail due to ruby 2.0 now being the default.
Our recommended fix is to upgrade to TextMate 2.0, which is a free¹ update and can be downloaded from https://macromates.com/download — the reason we still label it alpha is mainly because the manual is incomplete.
The preliminary manual is at http://manual.textmate.org/ and we have a dozen or so blog posts about 2.0 features at https://macromates.com/blog/categories/textmate-2/ but you can also email the mailing list or contact support with any questions, see https://macromates.com/contact.
