+# 1.1.1 (April 2, 2020)
+
+* Pool.Close can be safely called multiple times
+* AcquireAllIDle immediately returns nil if pool is closed
+* CreateResource checks if pool is closed before taking any action
+* Fix potential race condition when CreateResource and Close are called concurrently. CreateResource now checks if pool is closed before adding newly created resource to pool.

 # 1.1.0 (February 5, 2020)
 
 * Use runtime.nanotime for faster tracking of acquire time and last usage time.
