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 k0s?

k0s keeps four Kubernetes branches patched in lockstep, one backport at a time.

The release feed is four maintenance branches — 1.33 through 1.36 — moving in near-formation, plus a 1.37 alpha collecting the unbackported work. Almost every entry is a list of bot-authored bumps: Kubernetes patch versions, etcd, containerd, Calico, Traefik, CoreDNS, kube-router, Alpine and Go. The few human-authored items are small operational fixes, such as keeping the konnectivity server count above zero, distinguishing pending from performed restarts in Autopilot, and omitting an anonymous-auth default when the authentication config already sets it.

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.

5.0

k0s keeps four Kubernetes branches patched in lockstep, one backport at a time.

◆ Current state

The release feed is four maintenance branches — 1.33 through 1.36 — moving in near-formation, plus a 1.37 alpha collecting the unbackported work. Almost every entry is a list of bot-authored bumps: Kubernetes patch versions, etcd, containerd, Calico, Traefik, CoreDNS, kube-router, Alpine and Go. The few human-authored items are small operational fixes, such as keeping the konnectivity server count above zero, distinguishing pending from performed restarts in Autopilot, and omitting an anonymous-auth default when the authentication config already sets it.

◆ Where it's heading

This is a distribution whose product is currency and consistency: the same fix reaches every supported branch within days, and the component matrix stays close to upstream. Autopilot is the one area receiving actual behavior work rather than version bumps, which is where a self-managing cluster story would have to come from. The 1.37 alpha line is where riscv64 support and larger refactors are accumulating.

◆ Prediction

Expect the 1.37 line to move from alpha toward a release candidate with the riscv64 and etcd 3.7 work carried forward, while 1.33 through 1.36 continue their weekly bump cadence.
