This is a "service" version update with 42 fixes and 11 enhancements. Since 7.2 has introduced so many significant changes a service update is coming out hot on its heels to address any issues that may have been missed in 7.2.
Now the Dolphin.Pro 7.2.1 is the new stable version, with upgrade pack available from 7.2.
Upgrading to this new version is highly recommended. This time around we hope to be able to continue to 7.3 development without having to issue many service updates. A lot of great plans and exciting new features are on the table. Can't wait!
