Deno 2.6 introduces dx, a new command for running package binaries similar to npx. The release adds granular permission controls with --ignore-read and --ignore-env flags, integrates tsgo for faster type checking, and supports source phase imports for WebAssembly. New features include deno audit for security vulnerability scanning, --require flag for CommonJS preloading, and improved dependency management with deno approve-scripts. The release enhances Node.js compatibility with @types/node included by default, numerous API fixes across crypto, fs, process, and sqlite modules, and better bundler support for different platforms. Additional improvements include transferable web streams, native source map support, and V8 14.2 upgrade.
