Changing the index format is not a sign of instability, we did this to improve performance. So, changing the index format is in no way a bad sign, nor indicative of whether or not the trunk is good for production use. You aren't forced to re-index all your documents if you are riding trunk -- its your decision to make that tradeoff when you type 'svn update'. If you want stability you can take a snapshot (e.g. nightly build), and just stick with it.
