What is prioritizr?

Conservation planning absorbs the literature's target-setting rules as code.

prioritizr builds and solves systematic conservation planning problems, handing them to CBC, HiGHS, Gurobi or SYMPHONY. The last two years moved it onto the sf and terra spatial stack and rewrote its internals as R6 classes; the newest release adds a target-setting layer with seventeen named methods from the conservation literature, plus automatic penalty calibration. Solver control parameters and neighbour penalties arrive in the same release.

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.

Conservation planning absorbs the literature's target-setting rules as code.

◆ Current state

prioritizr builds and solves systematic conservation planning problems, handing them to CBC, HiGHS, Gurobi or SYMPHONY. The last two years moved it onto the sf and terra spatial stack and rewrote its internals as R6 classes; the newest release adds a target-setting layer with seventeen named methods from the conservation literature, plus automatic penalty calibration. Solver control parameters and neighbour penalties arrive in the same release.

◆ Where it's heading

The package keeps absorbing decisions that used to sit with the analyst. Targets were something you computed and passed in; now add_auto_targets() takes a method specification and the published rules from Jung, Rodrigues, Ward, Watson and Wilson are first-class objects. Penalty values were tuned by hand; calibrate_cohon_penalty() searches for them. The same instinct shows in exporting its validation helpers for other packages to vendor.

◆ Prediction

The deprecation of add_loglinear_targets() in favour of a spec function suggests the older manual target helpers are next to be folded into the same interface.

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.
