Air quality analysis rebuilt on ggplot2, twenty years of lattice plotting dropped in one release.
A side-by-side editorial comparison of IsoriX and projoint — release velocity, themes, recent moves, and the top alternatives to consider.
An isotope geolocation package still recovering from the r-spatial retirement
IsoriX builds isoscapes and assigns organisms to geographic origin from stable isotope data. Its recent history is defined by the October 2023 retirement of the old R spatial stack: version 0.9.1 recoded substantial parts of the package to drop raster and sp, 0.9.2 restored capabilities that migration had broken - saving and reloading IsoriX objects, and plotting ocean masks containing holes - and documented the new plotting calls that replace the old sp.polygons and sp.points idioms. Since then 0.9.3 revised the bundled bat calibration datasets and 0.9.4 moved the documentation off bookdown.org.
projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.
projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

Two years of the visible history have gone on infrastructure the science did not ask for. The 0.9.1 notes are unusually candid, warning users that the surrounding package landscape was still in flux and that incompatibility bugs were likely to keep surfacing, which 0.9.2 then confirmed. Only in 0.9.3 does domain work reappear: the bat fur isotope values in the calibration and assignment datasets were corrected to align with current keratin reference material normalisation, so results computed against the old datasets are not comparable with new ones.
With the spatial migration settled and the documentation rehomed, the next release is more likely to return to isoscape functionality than to infrastructure, though the entries do not name a specific feature.

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.
Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
