I'll most likely be releasing 1.0.1 later today, and I'll try to ship it with all user submitted bundles.
So if you've made changes or you have something you haven't published, please add it to the wiki [1]. When there are multiple bundles for the same language, be sure to add comments to why (or merge them ;) ) so that I can quickly get an overview of this stuff.
I'm planning to include all syntax highlight files in the "SharedSupport" folder of TextMate, so these will be available out-of-the-box. And then I'm also adding an external "support" folder to the disk image, where bundles are located which contain more than just syntax highlight files, which the user can then double click to get that extra support (TextMate will merge the default bundle with syntaxes with the installed bundle that contain the added functionality).
I'd hoped 1.0.1 would have had better bundle management from within TextMate, but this will take a little more time, and I think it's about time the 1.0.1 update was released -- this also means that some of the other things some of you may have been expecting for 1.0.1 didn't make it. Don't worry, I do write down every suggestion I get, so there's no need to re-send your feedback, at least not if I replied to it.
Kind regards Allan
