bkmrhat vs lifecontingencies: at a glance
What is bkmrhat?
A parallel-chain helper for bkmr that has settled into pure upkeep.
bkmrhat wraps Bayesian kernel machine regression (bkmr) so users can run and diagnose multiple MCMC chains in parallel, then combine or continue them. The functional surface has been stable since 2022, when chain-combining picked up a low-memory path and a seed-collision bug was corrected. The most recent release adds only diagnostic metadata to the package description.
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.

◆ Current state
bkmrhat wraps Bayesian kernel machine regression (bkmr) so users can run and diagnose multiple MCMC chains in parallel, then combine or continue them. The functional surface has been stable since 2022, when chain-combining picked up a low-memory path and a seed-collision bug was corrected. The most recent release adds only diagnostic metadata to the package description.
◆ Where it's heading
Three releases across five years, and the newest carries no user-facing change at all. The package is in maintenance: it does what it set out to do for bkmr users, and updates now arrive only when CRAN or an upstream dependency forces them.
◆ Prediction
Expect the next release to be another compliance or dependency-driven patch rather than new functionality; the entries show no in-progress feature work.

2.5INFRA · APIS
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.

exametrika
A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.
nuggets
nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.
projoint
projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.
eratosthenes
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
dqcheckr
dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
