 ### Known bugs
 
 * Doesn't work with ruby 2.4.0 for Windows (see [#36](https://gitlab.com/honeyryderchuck/httpx/issues/36)).
 * Using `total_timeout` along with the `:persistent` plugin [does not work as you might expect](https://gitlab.com/honeyryderchuck/httpx/-/wikis/Timeouts#total_timeout).
 
+## Versioning Policy
+
+Although 0.x software, `httpx` is considered API-stable and production-ready, i.e. current API or options may be subject to deprecation and emit log warnings, but can only effectively be removed in a major version change.
