Published: 2026-08-29 Tags: release npm patch

NextClaw v0.45.1 fixes a Portable Service App packaging defect in v0.45.0. After updating, the Daily Toolkit and other WebAssembly Component apps receive the native runner for the current platform as part of the Runtime.

Fixes

• Complete cross-platform runner packaging: Stable Runtime releases now build and package native runners for Linux x64, Windows x64, macOS arm64, and macOS x64. A release fails before upload if its runner is missing.
• Preserve Unix executable permissions: Runtime ZIP files retain file permissions, and the updater restores them during installation. A new Runtime installed by an older updater also repairs the runner permission at startup, so manual chmod is not required.
• Verify a real app call before completing a release: Published validation now checks that the runner exists and is executable, then invokes an included Portable Service App instead of checking only the version number.

What you need to do

Update normally to v0.45.1, then enable the Daily Toolkit again. Linux installations that previously failed because nextclaw-wasmtime-runner was missing do not require a manual file repair.
