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 semmcci?

Monte Carlo confidence intervals for SEM, now mostly reacting to upstream deprecations

semmcci generates Monte Carlo confidence intervals for structural equation model parameters, working alongside lavaan. Its four-year release history is a run of patch versions from the jeksterslab account, each adding a function or adjusting method detail. The recent ones are quieter still: the latest addresses a lavaan::getCov() deprecation in tests, and the one before it is described only as minor method edits.

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.

Monte Carlo confidence intervals for SEM, now mostly reacting to upstream deprecations

◆ Current state

semmcci generates Monte Carlo confidence intervals for structural equation model parameters, working alongside lavaan. Its four-year release history is a run of patch versions from the jeksterslab account, each adding a function or adjusting method detail. The recent ones are quieter still: the latest addresses a lavaan::getCov() deprecation in tests, and the one before it is described only as minor method edits.

◆ Where it's heading

The functional build-out finished some time ago. MCGeneric() in 1.1.3 and Func()/MCFunc() in 1.1.4 opened the package to user-defined functions of parameters, which is the natural end point for a Monte Carlo interval tool — once arbitrary functions are supported, there is little left to add. Since then releases have tracked lavaan's changes rather than semmcci's own direction, and the gap between them has stretched from months to over a year.

◆ Prediction

Expect the next release to be triggered by another lavaan deprecation rather than by new capability.
