# New features
* Added getattr() support in queries: https://docs.ponyorm.com/api_reference.html#getattr
# Backward incompatible changes
* #159: exceptions happened during flush() should not be wrapped with CommitException
Before this release an exception that happened in a hook(https://docs.ponyorm.com/api_reference.html#entity-hooks), could be raised in two ways - either wrapped into the CommitException or without wrapping. It depended if the exception happened during the execution of flush() or commit() function on the db_session exit. Now the exception happened inside the hook never will be wrapped into the CommitException.
* #190: Timedelta is not supported when using pymysql
