Full Release Notes

This patch release contains a number of bug fixes. Thanks for the reports and the help in debugging them!

Update: December 2020: This tag is the same as `v2.2.3`. Somehow, [an unauthorized tag `v2.2.2` was released from a fork](https://twitter.com/caddyserver/status/1338324878441603073). Because the Go module proxy is append-only, we created the `v2.2.3` tag so that v2.2.1 would remain the default "latest" until v2.3.0 stable is released in a few weeks.
