 #### Fixed
 
 * [#309](https://github.com/shlinkio/shlink/issues/309) Added missing favicon to prevent 404 errors logged when an error page is loaded in a browser.
+* [#310](https://github.com/shlinkio/shlink/issues/310) Fixed execution context not being properly detected, making `CloseDbConnectionMiddlware` to be always piped. Now the check is not even made, which simplifies everything.
