 +===== 2021-11-11: Discontinuation of the "Azure Dev Tools for Teaching" Program =====
 +
 +Due to new licensing provisions, we are no longer able to offer the “Azure Dev Tools for Teaching” licensing program. Via the program formerly known as "Microsoft Imagine" or "Microsoft Developer Network Academic Alliance (MSDNAA)", students and teaching staff in computer science and B-IT were able to access licensed MS software free of charge.\\

 +===== 2021-10-23: BigBlueButton Maintenance =====
 +
 +**Update:** the Upgrade was successfully completed.
 +
 +Starting at around 11:00 am, we will undergo a comprehensive upgrade of the entire BBB environment to the latest software versions. Since a long overdue restructuring of the load balancing and DB backend systems is pending at the same time, there is unfortunately a longer downtime. Basic functionalities may also be available again at short notice, but the cluster will not be able to develop its full scope of services until late in the afternoon. We expect the work to be completed around 5:00 p.m.\\

 +===== 2021-10-01: BigBlueButton slides and whiteboard functionality available again =====
 +
 +a workaround for the problem has just been implemented; Currently running
 +BBB meetings will not benefit from this yet, but the following ones
 +will once again have slides and whiteboard functionality.
 +
 +Please note that the workaround may fail on some systems due to
 +cached redirects; if this happens on your browser, please clear all of your browser caches that are associated with the BBB nodes
 +bbb-node*.informatik.uni-bonn.de or use a alternative browser until the redirects
 +in your standard browser have expired.
 +
 +Thus, the full functionality of the BBB should be restored for the time being.\\

 +===== 2021-10-01: BigBlueButton service without slide functionality =====
