Up to version 2.49 you used the
02packages argument to specify where a cached
02packages.details.txt.gz could be found. That argument no longer exists as of version 3.00, use the
mirror argument instead.
Up to version 2.49,
maxdepth => 0 would incorrectly return the whole tree. From version 3.00 it cuts the tree off at its root so will only return the module that you asked about. Not very useful, but correct.
In version 2.49 you used the
configreqs argument to specify that you were interested in configure-time requirements as well as build- and run-time requirements. That option no longer exists as of version 3.00, it will always report on configure, build, test, and run-time requirements.
