I believe you were away for a couple of weeks a few months ago and responded to an email regarding symbol versioning and library bumping. You said you wanted kensmith to wait until you got back and took a closer look. I forget the exact context and don't have the saved email. I _think_ it had something to do with symbol version dependencies not getting recorded in shared libraries, or something related to that. I also _think_ you said you had some changes in the pipe to fix that. But I could be remembering wrong. I wish I had the old email... -- Dan
