 ==========================================
 Throughout this document, it is assumed that the current Monitoring
-Plugins version is 2.2.1, and that we're about to publish version 2.3.
+Plugins version is 2.3.2, and that we're about to publish version 2.4.
 It is also assumed that the official repository on GitHub is tracked
 using the remote name `monitoring-plugins` (rather than `origin`).
 Before you start
 ----------------
- Check Travis CI status.
+- Check Github Actions status.
 - Update local Git repository to the current `master` tip.  For a
  maintenance release (e.g., version 2.3.2), update to the current
  `maint-2.3` tip, instead.
