+Version 5.4.1 is a patch releases to revert some changes from v5.3.0 and v5.4.1 that break the ABI of the modulo
+libraries. In particular, the addition of assignments in the C++ classes changed the ABI in ways that components and
+controllers built with previous versions of modulo might stop working. Using v5.3.0 or 5.4.0 is discouraged, and users
+should move to v5.4.1.

 - fix(controllers): safety check for predicate publisher access (#238)
 - fix: remove ABI breaking assignment methods from C++ components and controllers (#240)
