# 6.11.1

In this Version, a new configuration variable has been added, `FACEPHI_SELPHID_FACIALLIVENESS_IAD`, which allows setting the parameters of the IAD (Injection Attack Detection) filter in the liveness check engine. A problem with the License server has also been fixed `ON_PREMISE` with online activation. Cases of failure had been detected when trying to activate the License a second time.

```
# Disable IAD filters.
FACEPHI_SELPHID_FACIALLIVENESS_IAD=disable

# Variable not present or empty, IAD is enabled.
FACEPHI_SELPHID_FACIALLIVENESS_IAD=
```

### Added

* Configuration variable `FACEPHI_SELPHID_FACIALLIVENESS_IAD=disable` to disable the IAD (Injection Attack Detection) checks of the liveness check.

### Corrected

-`selphid-license-server` fault-tolerant in cases of double activation (offline activations).
