Land-change analysis in R that has spent six years defending one download link.
A side-by-side editorial comparison of eratosthenes and ore — release velocity, themes, recent moves, and the top alternatives to consider.
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().
A stable Oniguruma binding for R that ships correctness fixes and little else.
ore wraps the Oniguruma regex engine for R, and its recent history is entirely about making that binding safe rather than richer. The last three releases fix an infinite-loop hazard on zero-length matches, a named-group propagation bug, and locale detection at startup. The user-facing API has not moved since 1.7.1, when ore_file() began recording whether a file was read as binary.

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.
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.

This is a package in maintenance, not development. The changes cluster around C-level hygiene — memory leaks, buffer overruns, sprintf() removal, compiler warnings — which reads as keeping CRAN checks green rather than pursuing new capability. Releases arrive in pairs separated by minutes or in gaps of two years, a cadence typical of a package touched only when something breaks or a CRAN policy shifts.
The next release is most likely another correctness or toolchain fix rather than new regex functionality; the README's note about CRAN and mainline diverging suggests the two versions may be reconciled at some point, though the entries do not say when.
