There are two conventions that are being added to the image in 3.11:
- A class which can free up some objects without losing any useful state should implement a class-side freeSomeSpace method. The intent is that the user can run these methods at anytime to immediately decruft the image and fix some common problems. It is intended to do things like:
-- clear caches
-- remove broken entries (like obsolete classes)
- A class which can free up even more space, but does lose useful state should implement a cleanUp method. This is meant to be run whenever a release maintainer wants to release a new image. These scripts do things like:
-- reset preferences
-- re-initialize customizable entities
-- forget history or changesets
