 # Changelog
 
+## 3.0.1
+
+- Raised the minimum `guzzlehttp/guzzle` version to 7.15.2 and the dev `phpunit/phpunit` version to 10.5.62, so installs can no longer resolve releases with known security vulnerabilities. No API or behavior changes.
+
 ## 3.0.0
 
 - Replaced the old multi-API SDK with the new PHP SDK for the IPGeolocation.io IP Location API.
