+Appendix: compatibility roadmap
+===============================
+
+Wherever possible, we ensure that all functional changes in MKWS are
+backwards-compatible, so that applications written against old versions of the
+toolkit will continue to work when running against newer versions.
+
+However, a few aspects of functionality unavoidably change in backwards
+incompatible ways. We ensure that **this only happens with new major
+versions** -- so it should _always_ be safe to upgrade to a new minor version.
+As an aid to porting old applications, we here note the specific
+backwards-incompatible changes in the various major releases, and those
+planned for future major releases.
+
+
+Major version 1.x
+-----------------
+
+Versions of MKWS before v1.0 (including the only prior release, v0.9.1) used
+camel-case class-names: without hyphens and with second and subsequent words
+capitalised. So instead of `mkws-search`, it used to be `mkwsSearch`. And the
+classes used to specify team names used an `mkwsTeam_` prefix (with an
+underscore). So instead of `mkws-team-foo`, it used to be `mkwsTeam_foo`.
+
+The 1.x series of MKWS releases recognise these old-style class-names
+as well as the canonical ones, as a facility for backwards
+compatibility. However, **these old class-names are deprecated, and
+support will be removed in v2.0**. Existing applications that use them
+should be upgraded to the new-style class names as soon as convenient.
