0.2.18
Upgrading from 0.2.17: all V2 clients of nsqd now receive heartbeats (previously only clients that subscribed would receive heartbeats, excluding TCP producers).
Upgrading from 0.2.16: follow the notes in the 0.2.17 changelog for upgrading from 0.2.16.
Beyond the important note above regarding heartbeats this release includes nsq_tail, an extremely useful utility application that can be used to introspect a topic on the command line. If statsd is enabled (and graphite in nsqadmin) we added the ability to retrieve rates for display in nsqadmin.
We resolved a few critical issues with data consistency in nsqlookupd when channels and topics are deleted. First, deleting a topic would cause that producer to disappear from nsqlookupd for all topics. Second, deleting a channel would cause that producer to disappear from the topic list in nsqlookupd.
New Features / Enhancements:
- #131 - all V2 nsqd clients get heartbeats
- #154 - nsq_tail example reader
- #143 - display message rates in nsqadmin
