What is SoftEther VPN?

Post-quantum key exchange landed, then the release train went quiet.

SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.

What is Skipper?

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

Post-quantum key exchange landed, then the release train went quiet.

◆ Current state

SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.

◆ Where it's heading

The work is drifting from protocol features toward build and supply-chain hygiene, and the crypto addition arrived through submodule updates rather than in-house design. Release notes are thin enough that several tags credit contributors without describing what changed. With the newest entry now over a year old, this reads as a maintenance-paced project carried by a small group of contributors.

◆ Prediction

If the pattern holds, the next tag is another accumulation of CI and dependency work, with post-quantum defaults tightening as liboqs moves upstream. The entries give no signal of a new protocol or management-plane direction.

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

◆ Current state

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

◆ Where it's heading

Skipper is building out its security posture at the proxy layer: RFC 9421 request signing, Redis L2 cache (v0.27.92), and security header handling improvements (v0.27.88) suggest a consistent push toward production-grade security primitives without architectural breaks. The performance improvements in v0.27.95 address real-world Kubernetes clusters where large RouteGroup counts are common.

◆ Prediction

RFC 9421 support will likely get expanded configuration options — signing key rotation, policy enforcement modes, per-route key selection — as Zalando's internal adopters surface operational requirements for the filter.
