Garmin Forerunner 305 updates

Today, I visited the Garmin website and found that there are new updates to the forerunner 305:

GPS unit is now updated to 3.00 (was 2.9)
Unit software is updated to 2.80 (was 2.7)
Garmin Training Center is updated to 3.3.2 (was 3.2.3)

I have installed all of them. From the outlook, there is no major difference. But hope the new firmware fix some of the issues of the forerunner 305
