Release Notes

• This version requires much more Zookeeper disk space when zookeeper_logging is enabled, due to the ever-increasing logs. pvc-installer has been modified to accomplish this. A 16GB or 32GB dedicated /var/lib/zookepeer logical volume is recommended for optimal behaviour, and the /etc/cron.daily/zookeeper-vacuum script in the latest pvc-ansible has been modified to keep only 3 sets of logs versus the previous 14.
