R/qtl is in pure custodial mode: every recent release answers a compiler, not a user
A side-by-side editorial comparison of Fluent Bit and tidytransit — release velocity, themes, recent moves, and the top alternatives to consider.
Fluent Bit keeps two lines alive while the 5.x branch quietly opens 5.1.
Three release lines are visible at once. The 4.2 branch takes backported fixes — Stackdriver payload over-reads, Avro empty-map handling, Windows event-log enrichment. The 5.0 line carries the forward work. And a 5.1 line has appeared with two tags whose titles are raw commit messages about test changes, which is what this repository produces when a tag is cut off a routine commit rather than a prepared release.
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.

The engineering emphasis on the maintained branches is memory safety and protocol correctness in the input and output plugins: use-after-free in in_forward, over-reads in out_stackdriver, endian-safe gzip magic reads, oauth2 token parsing hardening. That is the profile of a project whose failure mode is a crash in someone else's log pipeline, and it is being worked systematically rather than opportunistically.
Expect the 4.2 backport stream to continue at roughly monthly cadence and the 5.1 line to keep accumulating commit-titled tags until a prepared announcement release appears with real notes.

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.
