Changes since 8.0.0-rc1:

- Two new hooks, `Cluster::on_subscribe()` and `Cluster::on_unsubscribe()` have  
been added to allow observing `Subscribe()` and `Unsubscribe()` calls on  
backends by Zeek scripts.
- A fix for reading SMB2 ReadResponse messages.
- A fix for `analyzer.log` missing the `proto` field.

Some highlights in the 8.0 release:

- C++ 20-capable compilers are now required to build Zeek.
- The ZeroMQ library is now a required dependency for Zeek. Broker continues to be our default cluster backend, but requiring ZeroMQ for building will allow us to change this more easily in the future.
- Support for new plugins for extending connection information was added. This allows plugin authors to add additional information to connections beyond the traditional five-tuple. A plugin to add VLAN tags is included.
- A new analyzer for Redis traffic was added.
- Lots of improvements to both the cluster and storage frameworks, including new metrics exposed by the telemetry framework.
