 ## Change Log
 
+* v0.22.0: Use fallback for endpoint detection. Should prevent most cases of `Unable to find LocalStack endpoint for service ...`
 * v0.21.1: Introducing semantic versioning and list of services without endpoints
 * v0.21: Use placeholder credentials and region only if Boto cannot not find them, fix output streaming for logs tail call
 * v0.20: Small fixes for Python 2.x backward compatibility
