+
+* `0.8`
+* `18.12`
+* `19.12`
+* Any version of the form `x.12` (LTS versions).

+**We do not support the latest version of Sanic.** Versions between LTS releases [have introduced breaking changes in the past](https://github.com/huge-success/sanic/issues/1532) without prior notice, so we cannot support them as they are too fast of a moving target.
+
+A Python version of 3.6 or greater is also required.
