Coarse-grained control over Actuator endpoint visibility is now possible, and structured logging is supported with Elastic Common Schema, Graylog Extended Log Format, and Logstash. OTLP spans can be sent over gRPC, and client certificates can be used for authentication in Couchbase clusters. FreeMarker variables in auto-configured FreeMarker configurations can be customized. Support for virtual threads has been added to OtlpMeterRegistry and Undertow, enhancing performance. Docker Compose now supports multiple configuration files and custom command line parameters. Spring Boot 3.4 uses a new builder that supports ARM and x64 platforms out of the box. GraalVM native images running on Apple Silicon in Buildpacks have been observed to perform faster than native macOS binaries.
