The Manhattan-plot package for GWAS results, finished and dormant since 2017.
A side-by-side editorial comparison of r-datetimeoffset and gtfstools — release velocity, themes, recent moves, and the top alternatives to consider.
A datetime type built for the messy metadata formats everyone else rounds off.
datetimeoffset provides a vctrs record type for datetimes with optional UTC offsets, possibly heterogeneous time zones, and missing components — the shapes that appear in PDF, XMP and exiftool metadata. Its value sits in the format family around that type: ISO 8601, EDTF, pdfmark, exiftool, nanotime and strftime output. The 1.0.0 release is a dependency bump, not a feature milestone.
gtfstools stopped guarding its own object model and started accepting everyone else's.
gtfstools reads, edits, filters and validates GTFS public transport feeds in R on a data.table backend. Since 1.3.0 it accepts GTFS objects produced by other packages such as gtfsio and tidytransit, converting them through an as_dt_gtfs() generic. Validation runs MobilityData's canonical validator, now supported through v6.0.0.

Growth has come by adding output dialects and loosening parsing rather than by changing the core record. Recent releases handle TOML's ISO 8601 subset and times with no associated date, both narrow gaps in an otherwise settled design. The package tracks the clock package closely and much of its release traffic is keeping that alignment.
Further format dialects and parser edge cases are the likely path; the 1.0.0 label suggests the author considers the record type itself stable.

Validation runs MobilityData's canonical validator, now supported through v6.0.0.
The package built out a wide function surface first — filters, geometry conversion, speed and duration calculations — then turned outward. Delegating validation to MobilityData's validator and accepting other packages' objects both trade self-sufficiency for a position inside the wider GTFS ecosystem. Deprecations are handled slowly, with old behaviour left as the default for a release or more.
Expect continued validator version tracking and further completion of the deprecation cycle around filter_by_stop_id()'s full_trips behaviour.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. r-datetimeoffset and gtfstools 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. r-datetimeoffset and gtfstools are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
