+== Changelog ==
+
+To help implementers understand updates to this document, we attach a version number that resembles ''semantic versioning'' (<code>MAJOR.MINOR.PATCH</code>).
+The <code>MAJOR</code> version is incremented if changes to the BIP are introduced that are incompatible with prior versions.
+The <code>MINOR</code> version is incremented whenever the inputs or the output of an algorithm changes in a backward-compatible way or new backward-compatible functionality is added.
+The <code>PATCH</code> version is incremented for other changes that are noteworthy (bug fixes, test vectors, important clarifications, etc.).
+
+* '''0.1.1''' (2026-04-16):

+* '''0.1.0''' (2025-01-13):
+** Initial version, merged as BIP-375.
