 the user of the Subplot software.
 
+# Version 0.4.2, released 2022-007-28
+
+- New feature: Subplot now supports example blocks: embedded files
+  that are in the subplot document only as examples, not for use by
+  scenarios.
+
+- Subplot error messages are now a little bit more specific as to the
+  cause, and what operation failed.
+
+- Subplot now uses the `time` crate instead of the `chrono` crate to
+  avoid a potential security issue.
+
+- Terminology change: we now refer to diagrams as diagrams, not
+  graphs.

 # Version 0.4.1 (subplotlib only), released 2022-04-17
