 - Run ``black`` on the entire source code
+- [watchmedo] Exclude ``FileOpenedEvent`` events from ``AutoRestartTrick``, and ``ShellCommandTrick``, to restore watchdog < 2.3.0 behavior. A better solution should be found in the future. (`#949 <https://github.com/gorakhargosh/watchdog/pull/949>`__)
 - Thanks to our beloved contributors: @BoboTiG
