| [iot-pmc] Californium - Milestone Release 4.0.0-M3 is available |
Dear Californians,the milestone release 4.0.0-M3 is now available at the Eclipse Repo and on Maven Central.
It comes with further cleanups and better support for systems using anonymous clients. Some dependencies have been update, namely netty.io (see CVE-2025-24970) and the aws.sdk. It also supports draft-ietf-tls-keylogfile for easier usage with WireShark.
If java 21 is used for runtime, it also adds support socket handling with java's virtual threads. That reduces the resources when a larger number of clients are emulated. It will still requires the resources for an UDP socket, so this shift the limit from 5000-1000 up to 30000-40000 active emulated clients per host.
For more details about the 4.0.0-M3, please refer to [1].You may fetch the selected binary core artefacts from Maven Central [2] or all binary artefacts, including Californium.Tools, from the Eclipse Repository [3].
