Skipper vs Unleash

Skipper is Zalando's HTTP router and reverse proxy, cut as a GitHub tag on essentially every merged commit: v0.27.42 through v0.27.50 landed inside eight days. The content of that stream is maintenance — dependency group bumps, CI action upgrades, test corrections, and one internal refactor pulling the Valkey Del command and ratelimit ring client injection apart. The single change with user-visible effect in this window is a fix to the proxy listener binding on an insecure address.

Nothing in these entries points to a direction change; the 0.27 line is in steady maintenance with supply-chain hygiene as the visible priority — oras-go pinned to a released version so osv-scanner stops flagging it, the CodeQL action upgraded, an OPA test hardened to deny requests with truncated bodies. The documentation change is the most revealing item: jwtValidation's behavior was unclear enough to prompt a proposed advisory, and the response was to clarify the docs rather than alter the code.

The tag stream will most likely continue at several releases a week with the same composition of dependency bumps and test fixes. These entries show no feature work in flight, so the next notable change is more likely another security-adjacent clarification than a new routing capability.
