 ### Fixed
 - Fixed bug wherein policy was not destroyed and recreated when compartment is changed (#389)
 - Fixed errors with terraform import because of missing vcn_id in `*.tfstate` files (internet_gateway, route_tables, dhcp_options) (#388, #379)
+- Fixed error where same retry token was being used for multiple requests in some development environments when auto retries were activated (Issue #170)
 
 ### Notes
 - Code refactoring was done as part of this release. Go source file names have changed, the `provider` directory has been added. Should not impact the users in any way.
