+# churon 0.1.13
+
+* Fix source installation when Rust is installed in `~/.cargo/bin` but is not
+  on `PATH`, as on the CRAN macOS builders. Rust version requirements continue
+  to be checked by `configure`.

-## Resubmission (0.1.12)
+## Update (0.1.13)
 
-This resubmission addresses the CRAN review of version 0.1.11:
+This update fixes the installation failures reported by the CRAN macOS
+release/oldrel checks and the additional M1mac check for version 0.1.12.
 
-* Removed the redundant "for R" from the title and quoted software names
-  consistently; MNIST is no longer quoted.
-* Added ONNX Runtime and GitHub release URLs to DESCRIPTION.
-* Documented the return types and meaning of `$.TensorInfo` results.
-* Replaced non-running placeholder examples with executable examples using
-  the bundled MNIST model, conditional on runtime availability.
-* Removed software installation calls from the installer examples.
-* Required an explicit `destdir` for runtime installation. The installer no
-  longer writes into the package library, and configures `ORT_DYLIB_PATH`
-  for the current session. Later-session configuration is documented.
-* Removed automatic R package installation from the development setup script.
+`configure` successfully finds Cargo and rustc under `~/.cargo/bin`, but the
+Makevars recipe ran a redundant `rustc --version` before adding that directory
+to PATH. On the CRAN builders this failed with `rustc: No such file or directory`.
 
-## Local validation (2026-09-11)
-
-* macOS arm64, R 4.5.2, Rust 1.97.1.
-* Runtime-enabled tests: 90 passed, no failures, warnings, or skips.
-* Offline `R CMD check --as-cran --no-manual`: 0 errors, 0 warnings, 1 note.
-  The note reports that current time could not be verified with network access
-  disabled. The official Debian `checkbashisms` utility was supplied for this check.
-  Package installation, documentation, examples, and tests passed.
+* Removed the redundant version commands from the Unix and Windows Makevars.
+  `configure` continues to enforce Cargo and rustc >= 1.88.0.
+* Applied the existing Unix Cargo PATH fallback to the Windows build as well.
+* Added a macOS CI regression check with Cargo and rustc removed from PATH.
 
 ## Additional notes
 
 Rust dependencies are vendored in the source package for offline builds.
 ONNX Runtime is not bundled. The dedicated installer downloads it only on
 explicit request with a user-supplied destination. Tests requiring a runtime
 are skipped when it is absent; tests do not download or install software.

-## Submission status
-
-Version 0.1.12 was uploaded and submitted through the CRAN web form on
-2026-09-11 (upload ID 354755). The maintainer subsequently confirmed publication on CRAN.
-The Git repository is being synchronized with the published 0.1.12 release.
