Upgrading from 0.2.18: there are no backward incompatible changes in this release.
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
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.
New Features / Enhancements:
- #131 - all V2 nsqd clients get heartbeats
- #154 - nsq_tail example reader
- #143 - display message rates in nsqadmin
Bug Fixes:
- #148 - store tombstone data per registration in nsqlookupd
- #153 - fix large graph formulas in nsqadmin
- #150/#151 - fix topics disappearing from nsqlookupd when channels are deleted
Upgrading from 0.2.16: IDENTIFY and SUB now return success responses (they previously only responded to errors). The official Go and Python libraries are forwards/backwards compatible with this change however 3rd party client libraries may not be.
Upgrading from 0.2.15: in #132 deprecations in SUB were removed as well as support for the old,
line oriented, nsqd metadata file format. For these reasons you should upgrade to 0.2.16 first.
New Features / Enhancements:
- #119 - add TOUCH command to nsqd
- #142 - add --broadcast-address flag to nsqd/nsqadmin (thanks @dustismo)
- #135 - atomic MPUB
- #133 - improved protocol fatal error handling and responses; IDENTIFY/SUB success responses
- #118 - switch nsqadmin actions to POST and require confirmation
- #117/#147 - nsqadmin action POST notifications
- #122 - configurable msg size limits
- #132 - deprecate identify in SUB and old nsqd metadata file format
Bug Fixes:
- #144 - empty channel should clear inflight/deferred messages
- #140 - fix MPUB protocol documentation
- #139 - fix nsqadmin handling of legacy statsd prefixes for graphs
- #138/#145 - fix nsqadmin action redirect handling
- #134 - nsqd to nsqlookupd registration fixes
- #129 - nsq_to_file gzip file versioning
- #106 - nsqlookupd topic producer tombstones
- #100 - sane handling of diskqueue read errors
- #123/#125 - fix notify related exit deadlock
Upgrading from 0.2.15: there are no backward incompatible changes in this release.
However, this release introduces the IDENTIFY command (which supersedes sending
metadata along with SUB) for clients of nsqd. The old functionality will be
removed in a future release.

- #177 - support broadcast_address
- #161 - connection pool goroutine safety
Upgrading from 0.3.0: This release requires NSQ binary version 0.2.17+ for TOUCH support.
- #119 - add TOUCH command
- #133 - improved handling of errors/magic
- #127 - send IDENTIFY (missed in #90)
- #16 - add backoff to Reader
Upgrading from 0.2.4: There are no backward incompatible changes to applications
written against the public nsq.Reader API.
However, there are a few backward incompatible changes to the API for applications that directly use other public methods, or properties of a few NSQ data types:
nsq.Message IDs are now a type nsq.MessageID (a [16]byte array). The signatures of
nsq.Finish() and nsq.Requeue() reflect this change.
nsq.SendCommand() and nsq.Frame() were removed in favor of nsq.SendFramedResponse().
nsq.Subscribe() no longer accepts shortId and longId. If upgrading your consumers
before upgrading your nsqd binaries to 0.2.16-rc.1 they will not be able to send the
optional custom identifiers.
