Hi all, We are pleased to announce that a new A21 SDK has been deployed in JLSE. This version 2019.9.30.013 includes multiple improvements, including USM support. For details please see the release notes in the wiki: https://wiki.jlse.anl.gov/download/attachments/26214592/SDK-Release-Notes-20... Modules will enable the newer SDK by default, but the older versions remain available for regression testing. As usual, please let us know of any issues you encounter and any improvements we can include. Regards, Carlos
