fossilsim
A fossil-record simulator that quietly grew a trait-evolution engine.
A side-by-side editorial comparison of grex and windex — release velocity, themes, recent moves, and the top alternatives to consider.
grex is a lookup table with a version number — it ships when the annotation moves.
grex converts the deprecated Ensembl gene IDs found in GTEx data into current gene symbols and identifiers, using org.Hs.eg.db as its reference. Its value is entirely in that bundled reference data, so a release either refreshes the mapping or does nothing to it. The 2025 release does nothing to it: GitHub Actions for the docs site, a check-note fix, and a smaller vignette.
Steady, unglamorous upkeep on a niche phylogenetic adaptation index.
windex calculates the Wheatsheaf index for measuring adaptation in a phylogenetic comparative framework, with supporting simulation tests and node-distance tooling. Recent releases have loosened the input format requirements, improved troubleshooting in treedatacheck, and added a barplot for fitted logistic regression models. The package's analytic core is unchanged across the visible window.

The annotation refreshes stopped. Between 2017 and 2019 the package tracked org.Hs.eg.db through four versions and added the GTEx V7 identifier set; since then the reference has stood still while the releases turned to packaging. That gap matters more here than it would elsewhere — a stale mapping table silently returns outdated symbols rather than failing, so the package's core asset ages invisibly.
Nothing in these entries signals a planned data refresh, and the six-year pattern suggests the next release will again be infrastructure. Users needing current annotations should check which org.Hs.eg.db version is bundled rather than assume the version number reflects it.

Every release in this window is a variation on the same theme: make existing functions easier to use and their plots easier to customise. Some releases exist only to satisfy CRAN policy changes with no functional difference. This is a stable single-purpose package where usability friction, not method development, drives the work.
Expect further small usability and plotting additions on the same roughly annual cadence; nothing here points to new methods.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. grex and windex are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. grex and windex are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
