Command "reset dhcp" gone?

Previous to v1.20 (at least in 1.1.8) there was a command

reset dhcp server leases

That would allow the release of all IPs in a pool or

reset dhcp server lease

would have you specify just one IP.

Was the command removed? Is there a replacement command?


I have exactly the same problem. How now to free the address occupied by the client or make him get it?
