New Features¶

• Redis driver retries actions for up to 15 times when met with errorconnecting to Redis.

New Features¶

• HashRing now accepts a new argumenthash_function, allowingusing a different hash function.

Bug Fixes¶

New Features¶

• Added support for Consul ACL tokens. Consul ACL tokens can be passed in asa parameterized argument. Requires python-consul2

Upgrade Notes¶

• Updated the python-consul library to python-consul2. The original library isno longer maintained while python-consul2 is reasonably maintained. Consul 1.4has a new ACL implementation, and Consul 1.7 includes some standards enforcementwhich break python-consul.

New Features¶

• The etcd3 and etcd3gw drivers now support TLS, by adding the ability tospecify ca_cert, cert_key and cert_cert files. For the etcd3gw driver,this is controlled by specifying “etcd3+https” in the coordination URL.

New Features¶

• Added heartbeat supported to the Consul driver so that locks would remain lockedinstead of timing out on the first TTL. This can be considered both a feature anda bug fix because previously the Consul driver would only hold the lock for thefirst TTL and behind the scenes Consul would release it due to the lack of sessionupdates. In order for the Consul driver to perform distributed locking properlyyou MUST utilize heartbeats!

Upgrade Notes¶

• Python 2.7 support has been dropped. The minimum version of Python nowsupported by tooz is Python 3.6.
