From https://oem.sena.com/shark/#features-sec I understand that the Shark MW is equivalent to Sena Spider RT1 functionality.

According to https://www.sena.com/stories/notice/sena-releases-firmware-updates-for-the-spider-st1/ there should be a firmware update for mesh 3.0 for the spider.

Would that imply that it's also available for the Sena for Shark mesh?
