# Supavisor v1.1.2 - allow_list and client_heartbeat_interval

[Released Supavisor v1.1.2](https://github.com/supabase/supavisor/releases/tag/v1.1.2)

## Notable
* `allow_list` field on the `tenant` to support network restrictions
* More docs
* `client_heartbeat_interval` on the `tenant` to detect zombie client connections
* Bug fixes
* Observability improvements

The `client_heartbeat_interval` helps us detect client connections from behind a load balancer which are dead but did not close the TCP connection correctly. This interval defaults to one minute but is configurable per `tenant`.

The `allow_list` field on the `tenant` takes a list of CIDR ranges and validates incoming connection addresses against this list. The incoming client address must be in one of these ranges to be accepted.
