+## 8.11.1 Release notes
+
+Adds `base64` dependency
+
+base64 was added to the gemspec, since starting in Ruby 3.4.0, base64 will no longer be part of the default gems and will no longer be in the standard library.
+
+base64 is used forAPI key and Cloud ID. The dependency used to be declared in transport, but it's not needed there since the implementation using it is in this codebase.
