+* [#2373](https://github.com/shlinkio/shlink/issues/2373) Ensure deprecation warnings do not end up escalated to `ErrorException`s by `ProblemDetailsMiddleware`.
+
+  In order to do this, Shlink will entirely ignore deprecation warnings when running in production, as those do not mean something is not working, but only that something will break in future versions.
