Node.js version 26.13.0, codenamed 'Lithium', has officially entered Long Term Support (LTS), ensuring maintenance until April 2029, though no new features were added beyond version 26.12.1. Key features from the 26.x line include the Temporal API enabled by default, an upgrade to V8 version 14.6, and the introduction of Undici 8 as the new HTTP layer, along with an extensive security patch addressing ten CVEs. This release marks the end of Node's traditional six-month release schedule, as future versions will adopt an annual release model starting with Node.js 27. Users are encouraged to verify they are on the patched version and to restart their processes to ensure they benefit from the security updates and improvements

Node.js 26.13.0 Lithium Reaches LTS, Support Through April 2029

Node.js 26.13.0 'Lithium' entered Long Term Support today, adding no new code beyond v26.12.1 but locking in maintenance through the end of April 2029. The line carries the big 26.x features into LTS: the Temporal API enabled by default, a V8 14.6 upgrade, and Undici 8 as the HTTP layer. It also inherits an aggressive October security patch set of ten CVEs, headlined by a Brotli decoder RCE fixed just before Imperva's red team published a "Node2Shell" exploit. Notably, 26 is the last major under Node's old six-monthly schedule, with v27 switching to an annual release model.
