This fixes authentication checking so that the $sessionID is consistently returned (sometimes it was returning the session object). (Note: $sessionID is returned on a successful login, while $session is returned when there is a cookie for an authenticated session.)
This fixes SIP so that it allows noblock checkouts, regardless of normal patron checkout blocks.
Explanation: The purpose of no block checkouts in SIP is to indicate that the SIP machine has made an offline ("store and forward") transaction. The patron already has the item. As such, the item must be checked out to the patron or the library risks losing the item due to lack of tracking. As such, no block checkouts should not be blocked under any circumstances.
31450 HTML customizations and news will not display on OPAC without a publication date
This fixes the display of news, HTML customizations, and pages on the OPAC - a publication date is now required for all types of additional content. Previously, news items and HTML customizations were not shown if they didn't have a publication date (this behavour was not obvious from the forms).
