When I first learned about the availability of version 2.3, I'd attempted to update SYNC 3 automatically using Wi-Fi. For some reason, I wasn't able to do the update this way, so I purchased a USB drive to perform the update manually.
I was eventually able to update the software, but the experience was anything but smooth.
Since this was my first time updating SYNC 3, I would mostly attribute this vexatious experience to my unfamiliarity of the overall process.
Now I'm wondering what all has changed. Are there any release notes for version 2.3 on the web that aren't completely vague?
