- Internal name for conditional portfolio sharing for specific IP addresses
ranges when set by a user is now userip, to distinguish from those set
for externalresponse (inrenal name: ip).
- Portfolio shareability setting in domain defaults (by affiliation), with
possible override for an individual user will apply to portfolio file
requests to a LON-CAPA node running 2.11, when the file owner's homeserver
is 2.12 (or later).
