 BREAKING CHANGES
 
+3.0.0
+
+* `DelayTypeFunc` accepts a new parameter `err` - this breaking change affects only your custom Delay Functions. This change allow [make delay functions based on error](examples/delay_based_on_error_test.go).
+
+
 1.0.2 -> 2.0.0
 
 * argument of `retry.Delay` is final delay (no multiplication by `retry.Units` anymore)
