+2.0.0 (2021-11-09)
+
+This is a major release. Lapin itself is API compatible with 1.0, however, due to changes in the
+underlying rabbitmq libraries and the elixir `amqp` library there are runtime breaking changes.
+
+This release requires Elixir 1.14+ and OTP 26+. Please note that rabbitmq does not recommend
+running on OTP 27 yet.
+
+Check `amqp` release notes for more details: https://github.com/pma/amqp/wiki/4.0-Release-Notes
+
+- Require Elixir 1.15+ and OTP 26+
+- Update CI
+- Rewrite the internals on `Lapin.Connection` to use `:gen_statem` and remove `Connection` dependency
