Hey,

time="Jun 18 21:25:33" level=info msg="Reloading event handlers and middlewares."
time="Jun 18 21:25:33" level=warning msg="Purging middleware: 'middleware'"
And this is what gets written when hitting the API after the reload.
time="Jun 18 21:26:13" level=error msg="Can't dispatch 'PostMiddleware', hook is not defined."
The new bundles filename had a point release bump between reloads and there was some changes made to the Post middleware but no files were added or removed from the bundle and the manifest.json did not change.
Cheers
