Cronicle vs Skipper: at a glance
What is Cronicle?
Cronicle fixes active-job privilege visibility and chains a run of security dependency patches
Cronicle's recent releases cluster around two themes: access control hardening and dependency security. The v0.9.131 fix applies category and server-group visibility checks to the active job API, login bootstrap, and websocket status payloads — closing a privilege bypass that exposed job activity to users without the right access. Alongside it, a string of vulnerability bumps (nodemailer, nanoid, sanitize-html) and the chained-event bug fix in v0.9.134 round out a security-focused cycle.
What is Skipper?
Skipper patches three real routing correctness bugs and ships multiarch Docker images in a dense fix cycle.
Skipper is in a high-cadence maintenance run — seven patch releases this week, almost all fixes and dependency bumps. The substantive changes address actual routing correctness: a bug where modResponseHeader silently dropped all but the first cookie (affecting any backend that sets multiple cookies), a float serialization failure that broke valid canary routes with small Traffic() probabilities, and a documentation error that caused filter names copied from the docs to fail silently. The multiarch Docker image in v0.27.108 is the week's only net-new capability.

Cronicle fixes active-job privilege visibility and chains a run of security dependency patches
◆ Current state
Cronicle's recent releases cluster around two themes: access control hardening and dependency security. The v0.9.131 fix applies category and server-group visibility checks to the active job API, login bootstrap, and websocket status payloads — closing a privilege bypass that exposed job activity to users without the right access. Alongside it, a string of vulnerability bumps (nodemailer, nanoid, sanitize-html) and the chained-event bug fix in v0.9.134 round out a security-focused cycle.
◆ Where it's heading
The access control fixes in v0.9.125 and v0.9.131 look like the output of a systematic privilege audit rather than isolated bug reports. Node.js v22 is now officially required, the project is testing against v24, and dependencies are being kept current — all signs of a maintained project, not an abandoned one. No major new features are visible in this window.
◆ Prediction
A few more targeted privilege-check patches are likely as the access control audit works through the surface. A 1.0 release milestone isn't signaled by anything in the current entries.
Skipper
7.5INFRA · APIS
Skipper patches three real routing correctness bugs and ships multiarch Docker images in a dense fix cycle.
◆ Current state
Skipper is in a high-cadence maintenance run — seven patch releases this week, almost all fixes and dependency bumps. The substantive changes address actual routing correctness: a bug where modResponseHeader silently dropped all but the first cookie (affecting any backend that sets multiple cookies), a float serialization failure that broke valid canary routes with small Traffic() probabilities, and a documentation error that caused filter names copied from the docs to fail silently. The multiarch Docker image in v0.27.108 is the week's only net-new capability.
◆ Where it's heading
Skipper is in a hardening phase with no apparent new feature direction in recent releases. The multiarch image signals infrastructure modernization for mixed-hardware Kubernetes deployments. Historically, Skipper alternates between fix-heavy runs and feature batches; this dense patch cycle suggests a feature release could follow. The active dependency bumping keeps the dependency graph current but adds no user-visible capability.
◆ Prediction
Expect continued patch releases before any new filter types or routing capabilities land. Multiarch support may expand to additional registry targets, and the recent focus on route serialization correctness could precede a larger routing engine change.
