The messy-date parser rewrote its core in Rust and came out 300x faster.
A side-by-side editorial comparison of Athlytics and webchem — release velocity, themes, recent moves, and the top alternatives to consider.
A Strava analytics package spent its 1.0 cycle surviving rOpenSci review, not adding features.
Athlytics computes endurance-training metrics — ACWR, EWMA load, efficiency factor, decoupling, personal bests — from Strava exports. Every release in view is review-driven: test-suite consolidation, dataset renames, styler passes, and a substantial robustness pass over the metric calculations and stream parsers. 1.0.6 explicitly changes nothing but packaging metadata.
Adding chemical databases with one hand while public ones close programmatic access with the other.
webchem is the R interface to public chemical data — retrieving identifiers, properties and structures across roughly a dozen web services. Its release history reads as a running account of which of those services still allow automated access. Version 1.3.0 removed two functions outright because their sources withdrew: ChemIDplus was retired by the NLM, and PAN stopped supporting programmatic access. Version 1.3.1 continues the pattern, updating URLs that stopped working and noting that ChemSpider InChIKey validation now requires an API key like the rest of that provider's endpoints.

The package is optimising for credibility rather than surface area. It completed rOpenSci peer review, moved to an offline ZIP export workflow with hardened TCX/GPX parsing, corrected the EWMA half-life mapping, and deliberately softened its ACWR language away from injury-risk claims. Version numbers are also being published out of order, which makes the feed a poor guide to what shipped when.
With review complete and packaging metadata frozen for archival, the next substantive release is more likely to extend metric coverage or data sources than to continue polishing; nothing in these entries points to a specific new metric.

Two opposing forces run through these entries. The package keeps widening its coverage — ChEMBL in 1.2.0, LIPID MAPS and SwissLipids identifiers via Wikidata, structure images, Mol export — while the open, unauthenticated end of the chemical web keeps contracting. The other consistent thread is interface harmonisation: successive releases have converged the get_* functions on the same query and from arguments, tibble returns, and CAS reformatting, so the package feels like one interface rather than a dozen wrappers.
Expect further defunct functions and URL repairs as more providers move behind keys or shut down, alongside occasional additions of sources that remain open. The entries show no sign of a general credential-management layer, which is what a package facing this trend would eventually need.
