As we have previously announced, Blackboard Learn 9.1’s Q4 2019 release uses a new version of Java, Java 11 JDK. Java are the libraries on which the Learn application runs and also the libraries that power Building Blocks, the add-on tools and features you may use in your environment. We’re implementing Java 11 to improve security and performance. Staying on recently updated libraries is crucial to staying ahead of those who may try to compromise your learning environment.
In this release, if Blackboard Learn is involved in the authentication process (default authentication type or LDAP), administrators can decide when Learn locks user accounts to protect them from unauthorized access .
