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 Workato?
Workato's Genies just stopped being a chat feature and became an embeddable runtime.
Workato is shipping on two tracks. The agent track has moved fast: the MCP registry, tool annotations and named tokens landed generally available within days of each other, and now the Headless API removes the requirement that a Genie be reached through Slack, Teams or Workato GO at all. The integration track continues its older rhythm — expanded data-pipeline connectivity across ERP, finance and HR sources, cross-workspace event topic sharing, and a monthly community connector drop.

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.
Workato
8.8DEVOPS
Workato's Genies just stopped being a chat feature and became an embeddable runtime.
◆ Current state
Workato is shipping on two tracks. The agent track has moved fast: the MCP registry, tool annotations and named tokens landed generally available within days of each other, and now the Headless API removes the requirement that a Genie be reached through Slack, Teams or Workato GO at all. The integration track continues its older rhythm — expanded data-pipeline connectivity across ERP, finance and HR sources, cross-workspace event topic sharing, and a monthly community connector drop.
◆ Where it's heading
The through-line is governance of things Workato does not itself control, now extended to the surface a Genie runs on. The registry made servers and tools discoverable and attributable, annotations let clients tell a routine read from a destructive write, named tokens gave per-user attribution — and the Headless API keeps that scaffolding while letting the agent be invoked from a CI pipeline, a batch job, or another agent. Combined with AIRO MCP, the full lifecycle of a Genie can now be driven without opening the UI, which is the shape of infrastructure rather than an application.
◆ Prediction
Expect the Headless API to leave open beta with usage-based metering attached, since a Genie invoked from a CI pipeline has no seat to bill against. The dedicated runtime role and per-client IP allow lists suggest enterprise procurement questions are already being asked.
