If you have Bluebeam Revu 2018 on your system, there is a new update that was just released. 2018.2 is now available for you to upgrade to. To access the update, in Revu, go to the Help menu and click on Check for Updates.
If you need to download the update outside of the program (for all you IT type folks that don't use the program, although you should), it can be found on the Bluebeam website here: https://support.bluebeam.com/updates/
For a list of the enhancements and fixes, the readme is available HERE.
