- Bug 6121.
- Display of "Upload PDF Forms" in Main Menu in a course/community
controlled by domain default or course configuration.
courseprefs.pm
- lonnet::delenv() used to update current user's session when a
course environment setting is deleted.
domainprefs.pm
- code moved from &print_helpsettings() to &radiobutton_prefs()
to facilitate reuse in course defaults menu (canuse_pdfforms).
lonnet.pm
- canuse_pdfforms domain default cached in domdefaults.
