JointFPM vs q2
A side-by-side editorial comparison of JointFPM and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
JointFPM vs q2: at a glance
What is JointFPM?
Recurrent-event modelling settles, with mean_no() promoted to stable.
JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.
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.

JointFPM
0.0INFRA · APIS
Recurrent-event modelling settles, with mean_no() promoted to stable.
◆ Current state
JointFPM fits joint flexible parametric models for a recurrent event process alongside a competing terminal event, and predicts the mean number of events. The visible history runs from bug fixes on the earliest CRAN releases through standardization, integration options and a summary method, ending with mean_no() declared stable. Several changes arrived through outside pull requests.
◆ Where it's heading
The arc runs from a working estimator toward a usable one: input validation and error messages first, then control over the numerical integration, then a summary method and pass-through arguments to the underlying rstpm2 fit. The latest release adds no code so much as a stability commitment to a function users were already calling.
◆ Prediction
With mean_no() stable, the next work most likely targets the prediction and standardization paths rather than the model fit itself.
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.
