Upcoming breaking changes for NPM v12

NPM v12, releasing in July 2026, will introduce significant security changes that disable automatic execution of installation scripts and restrict Git and remote URL dependencies by default. Users can prepare now by upgrading to npm 11.16.0 or later to see warnings, then explicitly approve trusted packages using `npm approve-scripts` and `npm deny-scripts` commands, with their allowlist saved to package.json. These changes convert current automatic behaviors into opt-in features to reduce security vulnerabilities from untrusted dependencies.
