Announcement Details:

Blackboard is pleased to announce the availability of Cumulative Update 8 for the Blackboard Learn 9.1, Q4 2018 Release (Build: 3500.0.8-rel.13+ba67594).

Resolved Issues: 

Cumulative Update 8 for Blackboard Learn 9.1, Q4 2018 includes resolution to the following issues:
  • Lock Icon active in child course, can switch course availability - Article #50780
  • Long Load Times on Authentication Provider Page Caused by Updating Authentication Log Counts - Article #49892
  • Move Legacy Content to Content System (Xythos) as part of the SaaS migration moves the Turn It In Feedback files - Article #50866
  • As a short term workaround to Quick Enroll not granting Course Administrators access to the course home folder (Article #50390), a new bbconfig property, bbconfig.cs.principal.cache.expiration.seconds, has been added to Q4 2018 Cumulative Update 8 to control the cache expiration time.  If the property is empty, the default is 12 minutes to expire the cached items.  If set to a short time, for example 60 seconds, it will take a minute before the user can access the course content.  When adjusting this setting, it should not go below 30 seconds. The more frequently the principal cache items get refreshed can cause strain on the system.  After changing the value, PushConfigUpdates will need to be run.


Change Management Resources:

  • Self-hosted clients may download the latest build on the Download Files page.
Before applying the Cumulative Update, please take a system backup and make sure you have a backup plan in place. The installer is run at the command line, using Gradle, Maven, and an installer properties file. This also requires your system to be down for the upgrade/install. Further installation instructions can be found here.
  • Managed Hosting clients may submit a case on Behind the Blackboard to schedule implementation of this release.
