churon vs flashlight: at a glance
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 flashlight?
flashlight hit 1.0 by giving away its SHAP feature and making most of its API internal.
flashlight computes model-agnostic interpretability output — variable importance, partial dependence and effect profiles, breakdown plots — for fitted models in R. Version 1.0.0 in October 2025 executed a contraction announced two years earlier: add_shap() is deprecated in favour of the separate kernelshap and fastshap packages, type = "shap" is gone from every light_* function that accepted it, and eight previously exported helpers became internal. The release also restored compatibility with ggplot2 v4.

◆ 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.

0.0ANALYTICS
flashlight hit 1.0 by giving away its SHAP feature and making most of its API internal.
◆ Current state
flashlight computes model-agnostic interpretability output — variable importance, partial dependence and effect profiles, breakdown plots — for fitted models in R. Version 1.0.0 in October 2025 executed a contraction announced two years earlier: add_shap() is deprecated in favour of the separate kernelshap and fastshap packages, type = "shap" is gone from every light_* function that accepted it, and eight previously exported helpers became internal. The release also restored compatibility with ggplot2 v4.
◆ Where it's heading
The package is narrowing rather than growing, and doing it on a published schedule — 0.9.0 listed the breaking changes, 1.0.0 applied them essentially unchanged. Handing SHAP computation to dedicated packages leaves flashlight as an effects-and-profiles visualization layer rather than an all-purpose interpretability toolkit. Removing the ability to rename result columns via options() points the same way: fewer configuration surfaces, a smaller contract to maintain.
◆ Prediction
With the deprecation list from 0.9.0 now fully applied, the next releases most likely remove the functions currently deprecated rather than adding capability, and continue tracking ggplot2. The entries show no new analysis method in progress.
