 ## Unreleased
 * Bug fix: avoid precompilation cache miss when `check_bounds` option set.
+* Bug fix: `juliacall` set the environment variable `JULIA_PYTHONCALL_EXECUTABLE`
+  instead of `JULIA_PYTHONCALL_EXE`, so child Julia processes resolved a new
+  CondaPkg environment.
 
 ## 0.9.35 (2026-06-08)
 * Add option `lib` to JuliaCall. Setting this will skip the discovery subprocess.
