lifecontingencies vs openair: at a glance
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.
What is openair?
Air quality analysis rebuilt on ggplot2, twenty years of lattice plotting dropped in one release.
openair is the reference toolkit for UK and European air quality data analysis, covering import from national monitoring networks, time averaging, polar and trajectory plots, and trend estimation. Version 3.0.0 rewrote every plotting function in ggplot2 and removed lattice, latticeExtra, hexbin, and mapproj from the dependency tree; 3.1.0 followed six weeks later to settle how parameters reach those functions, remapping base and lattice graphics arguments to ggplot2 equivalents with a warning rather than failing outright.

◆ 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.
openair
0.0INFRA · APIS
Air quality analysis rebuilt on ggplot2, twenty years of lattice plotting dropped in one release.
◆ Current state
openair is the reference toolkit for UK and European air quality data analysis, covering import from national monitoring networks, time averaging, polar and trajectory plots, and trend estimation. Version 3.0.0 rewrote every plotting function in ggplot2 and removed lattice, latticeExtra, hexbin, and mapproj from the dependency tree; 3.1.0 followed six weeks later to settle how parameters reach those functions, remapping base and lattice graphics arguments to ggplot2 equivalents with a warning rather than failing outright.
◆ Where it's heading
Two threads run through these releases. The first is the rendering migration and its long tail — deprecated arguments rehomed into breakOpts(), graphical parameters standardized on ggplot2 conventions, trajectory projections collapsed from three arguments into a single crs. The second is data access decaying underneath the package: importEurope() now errors for recent years because the database behind it was retired, while importUKAQ() gained automatic source detection and steadily more careful ratification handling. Correctness fixes keep landing in the analytical core too, including a corrected TheilSen intercept and more consistent bin boundaries in multi-period time averaging.
◆ Prediction
The migration is not finished — 3.1.0 is still remapping legacy graphics arguments with warnings — so expect a release that turns those deprecations into removals, and continued churn around European data import while the replacement service settles.
