upgrading some apps from 1.2.3 -->> 1.2.5 and having all kinds of issues. lot's of functions have disappeared between versions, for instance #default_value in the pg connection adapter which breaks drysql, render_action disappearing (as indicated in past versions of course) which breaks active scaffold... etc.
none of this is a big deal or hard to fix, but it did surprise me given that it's only a minor version number which, in most circles would allow api additions and fixes, but no deletions or changes to calling signatures.
what is the rails' versioning number policy?
if this is posted somewhere i didn't have success finding it, apologies in advance.
