Up to now, we've been releasing all the (eligible) sandbox projects at one go, with one "version" number, kept in sync with the UIMA base sdk version.
We can choose to change this to updating each add-on separately. If we did that, then an add-on could be released on its own schedule, whenever a change was needed, and add-ons that didn't change wouldn't need to be re-released just to be part of a bigger pack of add-ons. I think I prefer this approach. Any other opinions? -Marshall
