+# 2.2.1 (July 15, 2023)
+
+* Fix: CreateResource cannot overflow pool. This changes documented behavior of CreateResource. Previously,
+  CreateResource could create a resource even if the pool was full. This could cause the pool to overflow. While this
+  was documented, it was documenting incorrect behavior. CreateResource now returns an error if the pool is full.

 # 2.2.0 (February 11, 2023)
 
 * Use Go 1.19 atomics and drop go.uber.org/atomic dependency
