 # Deploying
 
-A reminder for the maintainers on how to deploy.
-Make sure all your changes are committed (including an entry in `CHANGELOG.md`).
-Then run:
-
-```bash
-$ bump2version patch # possible: major / minor / patch
-$ git push
-$ git push --tags
-```
-
-Travis will then deploy to PyPI if tests pass.
+This is now handled by github actions - there is a manual release action.

+## Version 2
+
+Despite the bump in version number there are no known major incompatibilities
+from previous versions.  However the underlying class base has been changed
+to a vanilla python slots based system - the thinking behind this is in the
+API internals documentation.  This will change the underlying requirements.
+
+Additionally at the same time I have converted to Broadworks R24 API schema
+files as the basis for generating these classes.

+The class used to be built using Michael DeHaan's [`ClassForge`]
