I've released kumofs-0.4.10.
This minor release fixes a bug that kumo-gateway sends "not found" response on getq/getkq command when the key is expired.
On the memcached's binary protocol, getq and getkq doesn't expect error response including "not found", so server should say nothing.
The latest version is available from github:

Thanks,
