Adding to Joe's information:

I would say that the easy way is to download and install the Prime Connectivity Kit. It will allow you to check for the latest firmware release.
In the firmware downloaded package you can find the release notes (that's a text file; if using Windows open it with Wordpad to see the text formatted for Windows).

Here is the firmware 5447 release notes file contents:
