A Prism-styled ggplot2 theme in maintenance, now surviving ggplot2 4.0.
A side-by-side editorial comparison of q2 and samplr — release velocity, themes, recent moves, and the top alternatives to consider.
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.
A cognitive-science sampling package ships once, then goes quiet for eighteen months
samplr compares human performance against sampling algorithms, giving cognitive scientists the MCMC machinery to test whether people behave like samplers. Its entire public history is three releases: a 1.0.0 in August 2024, a floating-point fix eighteen seconds later, and then nothing until a February 2026 patch. The release notes are unusually thin even by CRAN standards.

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.

The feed shows a package that shipped and stopped. The 2024 tags were both created in one sitting and say almost nothing; the 2026 release is a row-count bug in Mean_Variance() bundled with citation metadata, a dropped dependency and http-to-https link fixes — the housekeeping profile of a package being kept alive for the paper that cites it rather than actively developed.
Adding citation information to the README is usually the move of a maintainer expecting the package to be referenced rather than extended. On this cadence the next release is more likely another CRAN-hygiene patch than new algorithms; there is not enough in these notes to say otherwise.
