The protist reference database keeps widening past the rRNA gene it was built on.
A side-by-side editorial comparison of multimark and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
Five years of compiler and CRAN fixes on a capture-recapture package.
multimark fits capture-mark-recapture models for populations sampled with multiple non-invasive marks, including a spatial variant. Nothing in the visible history changes the models. Every recent release responds to something outside the package: a CRAN check, a compiler flag, or an upstream package that stopped exporting a function.
Quarto's Rust rewrite ships daily, and the parity grind has resumed after its one leap ahead.
q2 is the Rust reimplementation of Quarto, shipping a tagged release most days and still labelled experimental and not production-ready. The releases in this window are dominated by Quarto 1 parity work — tabsets, table-of-contents fidelity, highlight themes, path resolution, draft banners — plus a Hub web client that now carries its own accessibility and design-token workstream. Release notes are raw commit logs behind a fixed install header, so what actually changed sits well down the body.

This is preservation rather than development. The one substantive entry, in 2021, corrected an MCMC error in multimarkClosedSCR() serious enough that the author told users to revisit past analyses; everything since has been keeping the C code compiling across platforms. Release intervals now stretch to years.
Expect the pattern to hold, with a release whenever a toolchain or upstream dependency forces one and no change to the samplers.

Two things are being built at once. The compiler is closing a long checklist of Quarto 1 behaviours, and the pattern is consistent: investigate, settle the design in a plan, land in numbered phases, close the plan. The second is the Hub — a live-share preview, an MCP server, a web editor and now a WCAG-compliant token system — which is where the project is building something Quarto 1 never had. Recent tags have gone back to parity after v0.22.0's push, and the engine-claims refactor in v0.24.0 suggests third-party engine support is being prepared underneath.
The engine-claims work replaced a static source-type model with a claim-based one and added user-facing engine load and claim failure reporting, so the next visible step is likely an engine extension surface that authors can actually target. The experimental label and 0.x versioning give no indication that a stable release is close.
