+## 2026-10-28, Version 26.13.0 'Lithium' (LTS), @richardlau
+
+### Notable Changes
+
+This release marks the transition of Node.js 26.x into Long Term Support (LTS)
+with the codename 'Lithium'. It will continue to receive updates through to
+the end of April 2029.
+
+Other than updating metadata, such as the `process.release` object, to reflect
+that the release is LTS, no further changes from Node.js 26.12.1 are included.
+
+If you are updating from an earlier Long Term Support release (e.g. Node.js 24
+or 22 or earlier) please note that since Node.js 25 the official binaries for
+Linux are linked against libatomic, which may need to be installed separately
+depending on your Linux distribution.
