# 1.4.6 (Apr 2, 2019)

This is a patch release primarily focused on bugs related to concurrency,
SSL connections and testing, and SASL authentication:


Client Concurrency Issues (Race Conditions / Deadlocks)

* Fix race condition in `protocol.send_bytes` (isamaru / PR #1752)
* Do not call `state_change_callback` with lock (dpkp / PR #1775)
* Additional BrokerConnection locks to synchronize protocol/IFR state (dpkp / PR #1768)
* Send pending requests before waiting for responses (dpkp / PR #1762)
* Avoid race condition on `client._conns` in send() (dpkp / PR #1772)
* Hold lock during `client.check_version` (dpkp / PR #1771)

Producer Wakeup / TimeoutError

* Dont wakeup during `maybe_refresh_metadata` -- it is only called by poll() (dpkp / PR #1769)
* Dont do client wakeup when sending from sender thread (dpkp / PR #1761)

SSL - Python3.7 Support / Bootstrap Hostname Verification / Testing

* Wrap SSL sockets after connecting for python3.7 compatibility (dpkp / PR #1754)
* Allow configuration of SSL Ciphers (dpkp / PR #1755)
* Maintain shadow cluster metadata for bootstrapping (dpkp / PR #1753)
* Generate SSL certificates for local testing (dpkp / PR #1756)
* Rename ssl.keystore.location and ssl.truststore.location config files (dpkp)
* Reset reconnect backoff on SSL connection (dpkp / PR #1777)

SASL - OAuthBearer support / api version bugfix

* Fix 0.8.2 protocol quick detection / fix SASL version check (dpkp / PR #1763)
* Update sasl configuration docstrings to include supported mechanisms (dpkp)
* Support SASL OAuthBearer Authentication (pt2pham / PR #1750)

Miscellaneous Bugfixes

* Dont force metadata refresh when closing unneeded bootstrap connections (dpkp / PR #1773)
* Fix possible AttributeError during conn._close_socket (dpkp / PR #1776)
* Return connection state explicitly after close in connect() (dpkp / PR #1778)
* Fix flaky conn tests that use time.time (dpkp / PR #1758)
* Add py to requirements-dev (dpkp)
* Fixups to benchmark scripts for py3 / new KafkaFixture interface (dpkp)
