What is churon?

churon is spending its entire release history getting a Rust ONNX binding through CRAN.

An R package wrapping ONNX Runtime through Rust. All three releases in the window land within four days and none of them adds a feature. 0.1.8 downgrades the ort crate to 2.0.0-rc.10 because rc.11 needs Rust Edition 2024 and CRAN's Windows machines run Rust 1.81. 0.1.10 removes the vendored Rust sources from git into a compressed tarball for offline builds, fixes the Windows extraction path, deletes dead Rust and R code, and bumps ONNX Runtime to 1.23.2.

What is Rho?

Rho's release machinery is now more rigorous than the product it ships.

Rho is an R IDE in open prerelease, and its public feed is 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. Everything around it is build candidates and acceptance targets, each gated behind an explicit acceptance record that fails closed.

churon is spending its entire release history getting a Rust ONNX binding through CRAN.

◆ Current state

An R package wrapping ONNX Runtime through Rust. All three releases in the window land within four days and none of them adds a feature. 0.1.8 downgrades the ort crate to 2.0.0-rc.10 because rc.11 needs Rust Edition 2024 and CRAN's Windows machines run Rust 1.81. 0.1.10 removes the vendored Rust sources from git into a compressed tarball for offline builds, fixes the Windows extraction path, deletes dead Rust and R code, and bumps ONNX Runtime to 1.23.2.

◆ Where it's heading

Every visible decision is set by CRAN's build environment rather than by the package's own roadmap — pinned to an older ort release, vendored dependencies restructured for offline builds, and a dedicated CI job that simulates CRAN without network access. That is the standing cost of shipping a Rust-backed inference binding through R's distribution channel, and it is consuming the release stream entirely.

◆ Prediction

Expect the ort pin to move forward only when CRAN's Windows toolchain reaches a newer Rust, since that constraint is stated explicitly as the reason for the downgrade.

Rho's release machinery is now more rigorous than the product it ships.

◆ Current state

Rho is an R IDE in open prerelease, and its public feed is 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. Everything around it is build candidates and acceptance targets, each gated behind an explicit acceptance record that fails closed.

◆ Where it's heading

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, CONDITIONAL_GO records, checksums bound to exact commits, limitations named out loud rather than buried. dev.41 exists solely to rehearse the native updater across Windows and macOS, which is the last piece of distribution infrastructure between a dev train and something installable by people who won't build from source. Feature work and shipping work are advancing on separate tracks.

◆ Prediction

The updater acceptance target points at a 0.4.0 line that can update itself, so the next entry that matters is either dev.40's real publication or the first build not labelled evaluation-only. Whether Windows signing moves off the SignPath trial certificate is the open question these entries leave unanswered.
