I suggest a gluon/deprecated.py. This file would hold all deprecated
functions/classes. In say your configuation file, say options_std.py you
could set what version of web2py to run under, and if the version is less
that what the version currently is, it will grab and replace the appropriate
functions/classes with the ones in deprecated.py
