What is mlr3cmprsk?

Competing risks arrive in mlr3, going from a non-parametric baseline to Fine-Gray regression in seven weeks.

mlr3cmprsk extends mlr3 to competing-risks analysis: learners predicting cumulative incidence functions, plus measures to score them. It appeared in February 2026 and reached 0.0.5 by April, adding a Fine-Gray learner and a Brier score along the way. The version numbers say pre-release; the cadence says active build-out.

What is Rho?

Rho's release machinery finally produced a stable build — and it shipped no new product.

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

Competing risks arrive in mlr3, going from a non-parametric baseline to Fine-Gray regression in seven weeks.

◆ Current state

mlr3cmprsk extends mlr3 to competing-risks analysis: learners predicting cumulative incidence functions, plus measures to score them. It appeared in February 2026 and reached 0.0.5 by April, adding a Fine-Gray learner and a Brier score along the way. The version numbers say pre-release; the cadence says active build-out.

◆ Where it's heading

The package assembled a working evaluation stack fast. It started with the Aalen-Johansen estimator as a non-parametric baseline, added Fine-Gray as a regression alternative, then filled in the scoring side with an AUC refactor and a fixed-time Brier score. Development has run in lockstep with survdistr and mlr3extralearners, which picked up the dependency at 1.5.2.

◆ Prediction

The visible gaps are more learners — cause-specific Cox and boosting variants — and the tuning and pipeline integration the rest of mlr3 expects; the measure side currently looks further along than the model side.

Rho's release machinery finally produced a stable build — and it shipped no new product.

◆ Current state

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

◆ Where it's heading

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, checksums bound to exact commits, and limitations named out loud rather than buried. That discipline has now paid off in the only way it could — 0.4.0 stable ships a Windows installer, a notarized macOS disk image and a Linux AppImage that can all update themselves, with failed verification preserving the running version. The feed's long-standing pattern of dev.NN builds with no final has broken; feature work and shipping work were on separate tracks, and the shipping track arrived first.

◆ Prediction

With distribution solved, the next entry that matters is the first one describing product capability again rather than packaging. The unresolved item these releases name themselves is Windows trust: the installer is still signed with a SignPath Free Trial self-signed certificate that SmartScreen may warn on.
