eratosthenes vs lifecontingencies: at a glance
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 lifecontingencies?
An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.
lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.

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.

An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.
◆ Current state
lifecontingencies is a long-running R package for actuarial life-contingency mathematics. Its three most recent tags show a maintainer keeping the infrastructure alive rather than extending the library: 1.5.2 is entirely author-metadata corrections, CI workflow repairs and release automation, 1.4.4 moved presentValue() onto Rcpp, and 1.4.1 states outright that it is identical to the version before it. The 1.5.2 notes jump from 1.4.4, so whatever happened in between never reached this feed.
◆ Where it's heading
The one genuine engineering thread is performance: rewriting presentValue() in Rcpp targets the innermost loop of every annuity and insurance valuation the package performs. Everything since has been about keeping CRAN checks green across platforms — TinyTeX install order, cross-platform caching, automated release tagging — plus a set of Italian actuarial benchmark tests that pin results against published tables. That is maintenance discipline on a stable API, not expansion.
◆ Prediction
Expect further patch tags carrying CI and documentation work, with any Rcpp performance work extending from presentValue() into adjacent valuation functions if it continues at all.
