+# Upcoming Release
+
+- Any unhandled error is now logged to the configured rails logger by default. You can also now supply a custom callable that will be used to handle those exceptions instead.

+### Error Handling
+
+By default, scim_rails will output any unhandled exceptions to your configured rails logs.
+
+If you would like, you can supply a custom handler for exceptions in the initializer. The only requirement is that the value you supply responds to `#call`.
+
+For example, you might want to notify Honeybadger:
+
+```ruby
+ScimRails.configure do |config|
+  config.on_error = ->(e) { Honeybadger.notify(e) }
+end
+```
