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.

What is Windsurf?

Windsurf's own feature list has thinned out; what ships now is Devin arriving one surface at a time.

Across this stretch of the changelog, nearly every substantive release is a Devin capability landing inside the editor: the agent itself, Devin for Terminal, then Devin Review and Quick Review extended to all users on their existing subscription. The IDE-native work that remains is packaging around that — an agent inbox, session sorting, Windows stability. The other recurring release type is simply making new frontier models selectable.

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.

Windsurf's own feature list has thinned out; what ships now is Devin arriving one surface at a time.

◆ Current state

Across this stretch of the changelog, nearly every substantive release is a Devin capability landing inside the editor: the agent itself, Devin for Terminal, then Devin Review and Quick Review extended to all users on their existing subscription. The IDE-native work that remains is packaging around that — an agent inbox, session sorting, Windows stability. The other recurring release type is simply making new frontier models selectable.

◆ Where it's heading

Windsurf is converging on being the interface layer for Cognition's agent rather than an independently evolving editor. The pattern in these entries is consistent: a Devin surface ships, then it is unbundled from a separate purchase and folded into the existing subscription. Meanwhile the editor's own release notes are increasingly bug fixes and model availability notices, which is what a front end looks like when the differentiation has moved behind it.

◆ Prediction

Expect the next notable releases to be further Devin surfaces reaching general availability on the existing subscription rather than new editor features, and continued same-week model-availability notices. The entries give no signal on whether the JetBrains plugin gets the same Devin surfaces.
