Software Update: Node.js 15.13.0 / 12.22.0

Node.js is open source and platform independent, and is focused on developing server-side web applications. Those applications are written in JavaScript and run within the Node.js runtime on the server. It offers an event-driven environment in which non-blocking I/O has been an important starting point. For more information, please refer to this page† The development team has released version 15.13.0 in the current branch and version 12.22.0 in the lts branch. The main changes of these releases are as follows:

Node v15.13.0 (Current) – Notable Changes

• buffer: implement btoa and atob (James M Snell) #37529
• deps: upgrade npm to 7.7.6 (Ruy Adorno) #37968 This update adds workspaces support to npm run and npm exec
• doc: add legacy status to stability index (James M Snell) #37784
• doc: add @linkgoron to collaborators (Nitzan Uziely) #37817
• http: add http.ClientRequest.getRawHeaderNames() (simov) #37660

Node v12.22.0 (LTS) – Notable changes

• The legacy HTTP parser is runtime deprecated
  The legacy HTTP parser, selected by the –http-parser=legacy command line option, is deprecated with the pending End-of-Life of Node.js 10.x (where it is the only HTTP parser implementation provided) at the end of April 2021. It will now warn on use but otherwise continue to function and may be removed in a future Node.js 12.x release.
  The default HTTP parser based on llhttp is not affected. By default it is stricter than the now deprecated legacy HTTP parser. If interoperability with HTTP implementations that send invalid HTTP headers is required, the HTTP parser can be started in a less secure mode with the –insecure-http-parser command line option.
• ES Modules: ES Modules are now considered stable.
• node-api: Updated to node-api version 8 and added an experimental API to allow retrieval of the add-on file name.
• node-api: New API’s to control code coverage data collection v8.stopCoverage() and v8.takeCoverage() have been added.
• node-api: New API to monitor event loop utilization by Worker threads worker.performance.eventLoopUtilization() has been added.
