There’s only one update in this release: a fix for a potential race condition under some circumstances. Hopefully this will address the issues some users were having with v2.7.7. This release supersedes v2.7.7, i.e., if after upgrading you want to roll back, you’ll roll back to v2.7.6.
Upgrade steps:
Have your configuration backup ready. Create a backup file for your current configuration, if you don’t have one.
Click the “Check for Updates” button in the System Settings page. Follow the instructions to upgrade.
After successful upgrade, create a new router settings backup file from the System Settings page and save it in a safe place.
