Software to run the server has been updated for all platforms of Windows, Raspberry Pi, Mac, Android, & Linux.
For those running the earlier 2.x versions, the built-in self upgrade feature should allow you to do a smooth transition from the 2.x to the 3.x release version within the software automatically.
Many new features and improvements have been made over the older v2.x series, the changelog.txt will have all the details of what to expect.
The hack/exploit bounty still remains unclaimed, so there is still time to register to try for it.
