We upgraded to Blackboard Learn™ 9.1 Q2 2016 CU5 on 08/05/2017.
Blackboard Learn Cumulative Updates are focused specifically on changes where a tool or feature is not functioning as designed (software bugs), for performance, or to harden security. New functionality is not introduced as part of a Cumulative Update. There is an intent to minimize change to user interfaces as part of these Cumulative Updates so there is not an impact to end user support or documentation. Exceptions are occasionally made—for security hardening and performance in particular.
- Improve the performance of the content file indexer (as part of CU4)
- Resolution to ~70 issues (combined CU4 + CU5)
- Security fixes
