ggInterval vs Skipper: at a glance
What is ggInterval?
Interval-valued data plotting, spending 2026 making its function names and examples survive CRAN.
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
What is Skipper?
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.

◆ Current state
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
◆ Where it's heading
The package is consolidating an interface that had drifted. Renaming seven functions in a single release is the clearest signal — the naming was inconsistent enough to be worth breaking, and the vignette rewrite that followed suggests discoverability was the underlying complaint. Underneath that, the additions are steady and narrow: each release brings interval-aware versions of plot types that already exist for point data, which is the whole premise of the package.
◆ Prediction
The pattern of porting one more standard plot type into interval-aware form each release is the most likely continuation; the tsplot compatibility in the latest version hints that time-series interval data is the direction attracting attention.
Skipper
5.0INFRA · APIS
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
◆ Current state
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.
◆ Where it's heading
The release cadence is a stream of small, individually unremarkable tags where the occasional protocol or load-balancing change is the only thing worth reading. Recent substance has clustered on the data path: leastRequests balancing in v0.27.53, h2c now. The auth filters are being maintained rather than extended, with fixes rather than new capability.
◆ Prediction
Expect the h2c work to generate follow-up fixes as it meets real gRPC backends, since the release notes already show HTTP Upgrade negotiation failing while direct prior knowledge works.
