What is contagionchannels?

Three releases in ten days, every one of them a CRAN reviewer's correction rather than a code change.

contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.

What is HAProxy Kubernetes Ingress Controller?

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

Three releases in ten days, every one of them a CRAN reviewer's correction rather than a code change.

◆ Current state

contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.

◆ Where it's heading

There is no product trajectory to read here yet, only a submission one, and it is unusually well documented — each entry names the reviewer or check that prompted it and quotes the feedback verbatim. That transparency is the one signal available: the maintainer treats review rounds as releases worth publishing rather than squashing. Any judgement about direction will have to wait for a release that changes the package rather than its metadata.

◆ Prediction

With CRAN acceptance secured, the next release should be the first to carry actual methodological content; until one appears, there is not enough in these entries to say where the package is heading.

H2.5

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

◆ Current state

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

◆ Where it's heading

v3.2.13 is the largest release in the window and marks a shift from patching individual ssl-passthrough bugs to defining the semantics properly: backends are now reconciled rather than recreated, the invariant is applied before anything that can fail, and controller-owned backend state survives a failed transaction. Alongside it, ingress merge order became deterministic — oldest ingress first — and the first Ingress to constitute a backend now owns it, with the annotations a losing Ingress forfeits named explicitly. That pairing suggests the team traced a class of flapping and non-reproducible config bugs back to undefined ordering.

◆ Prediction

Expect the next few releases to stay on the 3.2 patch line, adding tests around the new ownership and passthrough invariants rather than new annotations.
