What is Libreswan?

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

What is Z-Wave JS UI?

Z-Wave JS UI is hardening its network surface while handing issue triage to agents.

The current tags are dependency bumps tracking the upstream zwave-js driver and server, which is the project's default rhythm between feature rounds. Behind them sit two substantive threads from the last two months: a security pass that confined store paths, blocked symlink escapes, stopped returning a password hash from the password endpoint and tightened TLS key permissions; and a repository bot rebuilt around agentic workflows with locally computed embeddings.

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

◆ Current state

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

◆ Where it's heading

The post-quantum work is the spine of this release and it is not experimental framing — it is standards-track RFC 9370 plus a hard dependency on NSS 3.118.1, meaning distributions have to move their crypto library before users can turn it on. Around it, the project keeps grinding on operator experience: better proposal parsing, more specific error messages, traffic selectors and DIGSIG algorithms in logs, and rate-limited logging. Experimental flags for subnet leasing and updown-config suggest the next capability additions are already staged.

◆ Prediction

Expect ML-KEM to move from supported to recommended in default proposals once NSS 3.118.1 is widely packaged, and the experimental leftaddresspool subnet leasing and per-connection debug options to stabilize in a following release.

Z5.0

Z-Wave JS UI is hardening its network surface while handing issue triage to agents.

◆ Current state

The current tags are dependency bumps tracking the upstream zwave-js driver and server, which is the project's default rhythm between feature rounds. Behind them sit two substantive threads from the last two months: a security pass that confined store paths, blocked symlink escapes, stopped returning a password hash from the password endpoint and tightened TLS key permissions; and a repository bot rebuilt around agentic workflows with locally computed embeddings.

◆ Where it's heading

Two directions are running in parallel. The product is tightening what a self-hosted controller exposes — credential management UI, trusted API on a separate network or port, store path confinement — which matters for a component that sits between a home network and physical devices. Separately, the maintainers are automating their own issue and docs workload with agentic triage, moving embedding computation in-house rather than depending on a hosted model service.

◆ Prediction

Expect continued driver-bump patch releases, with the next feature round most likely extending the trusted-API isolation or credential management surface, since those are the threads with unfinished work visible in the entries.
