Since latest update to 26.7.1, I cannot add Static IPs using the '+' sign on the console of ISC DHCPv4.

I get thrown an error as below:

Deprecated: The backtick (`) operator is deprecated, use shell_exec() instead in /usr/local/www/services_dhcp_edit.php on line 312

I have edited the file removing the (') and adding shell_exec() but still failing (?)

Best use KEA now, it's pretty much feature complete in the GUI.

The ISC plugin is legacy since a while now and EOL.

Does unbound DNS register KEA leases now?

It registers static leases, aka if you created a DHCP reservation it will register that.

For dynamic leases, no, and it's not planned to fix that.

You can use RFC2136 though, either with the community bind plugin or soon with the business edition's powerdns plugin when that's released (will be in the next business version).

Or you can find some community maintained scripts on github if you trust those.
