What is eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

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.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

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.
