Like and Like to Thomas and Martin.
SiuDic, start on your Administer/Backup page, save a ZD backup, and add the digits "961015" to the filename when you store it, so if you ever decide you need to downgrade back to 9.6.1.0.15, you can find this file and restore your current configuration. That's a best practice (that's built into the Upgrade procedure, asking you if you made a backup, but I'll pre-notify you now, so you can click Ok and continue to upgrade).
This might be the last 9.8 release for some time, and has all the updates and fixes for supported APs to date.
