paleobuddy can now simulate trait-dependent diversification, not just birth-death.
A side-by-side editorial comparison of Rpath and tidytransit — release velocity, themes, recent moves, and the top alternatives to consider.
Rpath 1.1.0 learns to read Ecopath's own files, easing migration off the desktop tool.
Rpath is NOAA's R implementation of the Ecopath with Ecosim mass-balance equations for marine food web models. The feed is an archive backfill and arrives out of version order, with several entries carrying only a journal abstract instead of release notes. The substantive recent work is 1.0.0, which paired real ecosim bug fixes with the documentation and packaging expected of a 1.0, and 1.1.0, which adds .eiixml import and new balance estimation.
tidytransit tracks the GTFS spec as it grows, one reader and one router feature at a time.
tidytransit reads GTFS transit feeds into tidy data frames and computes travel times using a RAPTOR implementation. Recent work splits between the reader keeping pace with the spec — locations.geojson in 1.7.0, empty strings parsed as NA in 1.8.0 — and the router gaining realism, most recently in-seat transfers. Feed specifications are now pulled from the automatically parsed GTFS reference rather than maintained by hand.

Development is moving from a faithful reimplementation of published equations toward a tool that can take over an existing modeling practice. Importing .eiixml files means models authored in the EwE desktop software no longer have to be rebuilt by hand, and the balance work reduces how many parameters a modeler must supply up front. The 1.0.0 release's contributor guidelines, issue templates and per-function examples point the same direction: preparing for users the maintainers do not personally know.
The next releases will likely widen the import path and tighten balance diagnostics, since 1.1.0 already spent effort on error messages for models missing parameters — the failure mode imported models will hit most.

Feed specifications are now pulled from the automatically parsed GTFS reference rather than maintained by hand.
The package has settled into tracking an external standard, which is why the changelog reads as a sequence of spec conformance items rather than a roadmap. Parsing responsibility keeps shifting outward to gtfsio, and data sources have moved with the ecosystem, from the retired transitfeeds API to MobilityData. Router changes are rarer than reader changes but land in the same releases.
Further GTFS spec features are the safest expectation, with GTFS-Flex the likeliest area now that locations.geojson reading is in place.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. Rpath and tidytransit 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.
