### Maglev load balancing for services

Calico Enterprise now supports Maglev consistent-hash load balancing for external traffic to services.
Maglev enables Calico Enterprise nodes to act as a distributed, horizontally scalable load balancer.
When a node goes down — for maintenance or otherwise — external connections can fail over to another node.
This is particularly useful when advertising service IPs as ECMP routes to your broader network.

Maglev is enabled per-service via annotation, keeping the memory footprint contained to only the services that need it.

For more information, see [Add Maglev load balancing to a service](../networking/configuring/add-maglev-load-balancing.mdx).

### Enhancements

* Improved the deterministic selection logic for flow and L7 logs when multiple NetworkSets have overlapping CIDRs.
