lifecontingencies vs openairmaps: 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 openairmaps?
The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.
openairmaps puts openair's air quality analysis onto interactive maps — polar markers on leaflet, trajectory paths and gridded trajectory levels, and popup construction from site metadata. It now requires openair 3.0.0 and R 4.1, and its polar markers are drawn by ggplot2 as a consequence, which brought a theme argument for customising them. The latest release turns off the automatic captions that openair 3.1.0 started adding, and points the remaining static trajectory functions at openair's own implementations.

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.
openairmaps
0.0INFRA · APIS
The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.
◆ Current state
openairmaps puts openair's air quality analysis onto interactive maps — polar markers on leaflet, trajectory paths and gridded trajectory levels, and popup construction from site metadata. It now requires openair 3.0.0 and R 4.1, and its polar markers are drawn by ggplot2 as a consequence, which brought a theme argument for customising them. The latest release turns off the automatic captions that openair 3.1.0 started adding, and points the remaining static trajectory functions at openair's own implementations.
◆ Where it's heading
This package follows rather than leads. The ggplot2 polar markers, the pipe change, and the R version floor all arrived because the parent package moved first, and the two now ship within hours of each other. The clearer local trend is contraction: the polarMapStatic() family has been removed outright, the static trajectory functions are now thin wrappers around openair equivalents with removal stated as the plan, and argument names keep being retired in favour of openair's. The package is narrowing toward the one thing openair does not do — interactive maps.
◆ Prediction
The static trajectory wrappers are explicitly flagged for removal, so the next significant release should drop them and leave the package purely interactive.
