nsq v0.2.19 Release Notes

Release Date: 2013-04-11 // about 11 years ago

  • ⬆️ Upgrading from 0.2.18: there are no backward incompatible changes in this release.

    🚀 This release is a small release that introduces one major client side feature and resolves one 🚑 critical bug.

    🔧 nsqd clients can now configure their own heartbeat interval. This is important because as of 0.2.18 all clients (including producers) received heartbeats by default. In certain cases receiving a heartbeat complicated "simple" clients that just wanted to produce messages and not 🖐 handle asynchronous responses. This gives flexibility for the client to decide how it would like behave.

    🚑 A critical bug was discovered where emptying a channel would leave client in-flight state inconsistent (it would not zero) which limited deliverability of messages to those clients.

    🆕 New Features / Enhancements:

    • #167 - 'go get' compatibility
    • #158 - allow nsqd clients to configure (or disable) heartbeats

    🐛 Bug Fixes:

    • #171 - fix race conditions identified testing against go 1.1 (scheduler improvements)
    • #160 - empty channel left in-flight count inconsistent (thanks @dmarkham)
