Please review the MindManager 15.1.173 Release Notes for the details. Several issues resolved. No new features.
You can download the latest version from MindManager 15 Service Pack 15.1.173.
I installed the Service Pack after closing MindManager but I failed to close the MS Office applications and Internet Explorer. This has not caused me any problems. But I advise closing them before doing the install.
The Olympics Limited MAP Add In had been disabled after the install. I re-enabled it in File > Options > Add Ins and it was fine.
