Annual public releases of sanitized code

[Crystalwarrior]

There are a few suggestions that would require the most up-to-date code to minimize pain and suffering, like the smell update, or updates which require newest features to be there (like footprint tracking - 2016 release doesn't have footprints).
Code snippets would also require a lot of work on the patcher's end due to the fact that newcode might use a lot of newdependencies and those newdependencies are dependant on other newdependencies and oldcode dependency breaks newcode dependency... you get the gist.
