2026-04 monthly summary for jdx/mise: Delivered a robust runtime environment detection fallback for minimal containers lacking a dynamic linker, improving lockfile correctness and reliability in minimal Docker images. Key changes ensure the binary detects musl correctly when no /lib/ld-linux-* or /lib/ld-musl-* linkers are present, so mise uses the compile-time target env (musl) rather than defaulting to glibc. This aligns with existing patterns (bun plugin uses cfg!(target_env = "musl")). Impact: fewer incorrect lockfile entries, fewer install failures in scratch/busybox environments, and better predictability in CI/CD pipelines. Work involved updating src/platform.rs and crates/vfox/src/config.rs; commits include ac3aa3a1e352d219c3d982344f0dab09f0bfc464. Test plan includes cargo check verification and cross-environment validation.

March 2026: Windows reshim reliability improvements for jdx/mise. Addressed a regression that caused reshim to fail when deleting shims if a shim executable was locked, by introducing a rename fallback and safer per-shim updates. Delivered a diff-based update approach that stops removing the entire shims directory in exe/hardlink modes and instead updates individual shims. Prepared for situations requiring a full rebuild by removing shims individually rather than via recursive removal. Commit 975007067f5ae55bb1984246125ff2a2f34b44bc documents the fix and its context; linked to the regression in v2026.2.7 (#8045). This work was co-authored with Davi De Castro Reis, autofix-ci[bot], Claude Opus 4.6, and jdx.
