ncmR vs q2: at a glance
What is ncmR?
Three weeks from first CRAN submission to a point-and-click neutral community model
ncmR fits the neutral community model to microbiome and ecological abundance data. The whole feed is three weeks long: fit_ncm() and summary methods at 0.1.0 on 1 April, a scatter plot with fitted curve and confidence interval at 0.2.0, then a Shiny application wrapping both at 0.3.0, then a row-name bugfix. It is a new package moving fast in its first month.
What is q2?
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.

Three weeks from first CRAN submission to a point-and-click neutral community model
◆ Current state
ncmR fits the neutral community model to microbiome and ecological abundance data. The whole feed is three weeks long: fit_ncm() and summary methods at 0.1.0 on 1 April, a scatter plot with fitted curve and confidence interval at 0.2.0, then a Shiny application wrapping both at 0.3.0, then a row-name bugfix. It is a new package moving fast in its first month.
◆ Where it's heading
The direction is toward users who do not write R. Version 0.2.0 added plotting, 0.3.0 wrapped fitting and plotting in Shiny modules, and the same release deleted the Unicode plotting helpers introduced one version earlier because the dependency they existed for was removed. That willingness to throw away a week-old API suggests the surface is still being negotiated rather than settled.
◆ Prediction
With a fitting module and a plotting module in the app, the remaining gap is getting results back out — export of fitted parameters or figures from the Shiny session. The bugfix at 0.3.1 was in file upload, which is where a GUI's problems usually start.
q2
6.3INFRA · APIS
Quarto's Rust rewrite ships daily, and the parity grind has resumed after its one leap ahead.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
