   Due to version differences between the rdkafka gem and karafka-rdkafka gem, the agent could encounter an error when it tried to install rdkafka instrumentation. This has now been resolved. Thank you to @krisdigital for bringing this issue to our attention. [PR#2880](https://github.com/newrelic/newrelic-ruby-agent/pull/2880)
 
+- **Bugfix: Stop calling deprecated all_specs method to check for the presence of newrelic-grape**
+
+  In 9.14.0, we released a fix for calls to the deprecated `Bundler.rubygems.all_specs`, but the fix fell short for the agent's Grape instrumentation and deprecation warnings could still be raised. The condition has been simplified and deprecation warnings should no longer be raised. Thank you, [@excelsior](https://github.com/excelsior) for bringing this to our attention.
