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 MooseFS?

A year of pure maintenance while the 4.x line clears the runway for MooseFS 5.

MooseFS has shipped nothing but maintenance releases across the entire visible window. The last release carrying real capability work was 4.58.0, which fixed partial readdir and added directory-in-parts reading for multi-million-file directories; everything after it is correctness, packaging, and hardening. The 4.59.x releases are single-issue fixes reported by the community and by external security researchers.

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.

A year of pure maintenance while the 4.x line clears the runway for MooseFS 5.

◆ Current state

MooseFS has shipped nothing but maintenance releases across the entire visible window. The last release carrying real capability work was 4.58.0, which fixed partial readdir and added directory-in-parts reading for multi-million-file directories; everything after it is correctness, packaging, and hardening. The 4.59.x releases are single-issue fixes reported by the community and by external security researchers.

◆ Where it's heading

The line is consolidating rather than expanding. Two signals point the same way: 4.59.1 quietly updated license handling specifically so licenses can be refreshed ahead of MooseFS 5 migrations, and 4.58.4 spent its effort on Fedora spec files and a bootstrap rewrite. That is a project stabilizing a shipping branch and widening distribution while the next major version is built elsewhere.

◆ Prediction

The 4.59.x branch keeps absorbing community bug reports at a low cadence until MooseFS 5 arrives; the license-compatibility work in 4.59.1 is the clearest evidence that migration is the next milestone rather than more 4.x features.
