Node.js Releases Versions 24.20.0 LTS and 26.8.0 Current

Node.js 24.20.0 LTS Release

Node.js 24.20.0, designated as a Long Term Support (LTS) release, introduces several new features. Key among these is an expanded permission model, which includes `permission.drop` and `--permission-audit` for enhanced control over resource access. This version also implements package maps for module loading, improving how modules are resolved within applications.

WebAssembly and Other Enhancements in 24.20.0 LTS

A significant addition to Node.js 24.20.0 LTS is the enablement of WebAssembly JavaScript Promise Integration (JSPI), which improves interoperability with WebAssembly. Other updates include adding `using scopes` to `AsyncLocalStorage`, an `end` parameter to `buffer`, and updating root certificates to NSS 3.125. The test runner also gains `context.log()` and `test:log` events.

Node.js 26.8.0 Current Release

Node.js 26.8.0, the latest Current release, brings a set of incremental improvements and new features. This version updates root certificates to NSS 3.126 and enables SIV and GCM-SIV modes within the Cipher/Decipher APIs for cryptographic operations. Performance enhancements have been made to `net.BlockList` and the histogram implementation.

Additional Features in 26.8.0 Current

Further additions in Node.js 26.8.0 include a `--analyze` mode for `compare.js` in benchmarks, the stabilization of `TracingChannel` in `diagnostics_channel`, and statistical hypothesis testing for histograms in `perf_hooks`. The REPL now features basic syntax highlighting, and `StatementSync.prototype.close()` and `StatementSync.prototype[Symbol.dispose]()` have been added to `sqlite`. A non-throwing `MIMEType.parse` has been added to `util`, and `Zip` has been added to `zlib`.
