== Breaking Fix for Windows in Loopback Hostname Verification
= Preview of enhanced HTTP performance
You can now enable a more efficient way to handle JSON data in the HTTP layer.
This change increases throughput by ~5%, stabilizes response times, and reduces system resource usage.
In order to apply it, you need to explicitly enable the feature `http-optimized-serializers`.
NOTE: This feature is *preview*.

= Breaking Fix for Windows in Loopback Hostname Verification
This release introduces a breaking change for Windows users: setups that previously relied on custom machine names or non-standard hostnames for loopback (e.g., `127.0.0.1` resolving to a custom name) may require updates to their trusted domain configuration. Only `localhost` and `*.localhost` are now recognized for loopback verification.
Keycloak now consistently normalizes loopback addresses to `localhost` for domain verification across all platforms. This change ensures predictable behavior for trusted domain checks, regardless of the underlying OS.
