 associated libraries, especially with regards to changes visible to
 the user of the Subplot software.
 
+# Version 0.4.0, released XXXX-XX-XX
+
+- The largest change from the previous release is that Rust based
+  subplot scenario test suites are now considered supported.
+  You can find an example of this in the `examples/seq` project in
+  the Subplot source code.
+
+- To achieve this, bindings are now "polyglot" in the sense that they
+  are not language specific, though some bindings may only provide
+  implementations for particular languages (e.g. the daemon bindings
+  currently only support Python)
+
+- Subplot considers Rust 1.48.0 to be its MSRV. This is to enable
+  integration into certain distributions and to work with other projects
+  whose MSRVs are around that value.
+
+- A number of quality of life improvements around warning delivery,
+  template handling, etc. have been made. For the full details, see
+  the Git changelog.
