20090608 is out, with the notable feature being experimental support for loading tmSnippet files. They should be fully supported, with the exception that interpolated shell code (requiring a unix style shell be available) is ignored. Tab triggers get converted into key bindings on the fly, but ‘key equivalents’ defined in .tmSnippet files are ignored.
*.sublime-snippet files are still supported, and use the same syntax within the tag (with the exception that $0 is treated as the first field, rather than the last). I expect that the format of .sublime-snippet files will change in the future, when python code is able to be embedded in them.
I’m keen to hear about any issues that are found with the new snippet support.
Also in 20090608, auto complete may be given commands as available completions (and thus inline snippets etc). Part of this involved some spring cleaning on how commands are handled within Sublime, so I’m also keen to hear about any issues with menus, keybindings etc not working as they used to.
