0.3.7 - 2014-05-25

Upgrading from 0.3.6: There are no backward incompatible changes. THIS IS THE LAST STABLE RELEASE PROVIDING THIS API. Future releases will be based on the api in #30 and will not be backwards compatible!

This is a bug fix release relating to the refactoring done in 0.3.6.

• #32 - fix potential panic for race condition when # conns == 0
• #33/#34 - more granular connection locking

0.3.6 - 2014-04-29

Upgrading from 0.3.5: There are no backward incompatible changes.

This release includes a significant internal refactoring, designed to better encapsulate responsibility, see #19.

Specifically:

• make Conn public
• move transport responsibilities into Conn from Reader/Writer
• supply callbacks for hooking into Conn events

As part of the refactoring, a few additional clean exit related issues were resolved:

• wait group now includes all exit related goroutines
• ensure that readLoop exits before exiting cleanup
• always check messagesInFlight at readLoop exit
• close underlying connection last

0.3.5 - 2014-04-05

Upgrading from 0.3.4: There are no backward incompatible changes.

This release includes a few new features such as support for channel sampling and sending along a user agent string (which is now displayed in nsqadmin).

Also, a critical bug fix for potential deadlocks (thanks @kjk for reporting and help testing).

New Features/Improvements:

• #27 - reader logs disambiguate topic/channel
• #22 - channel sampling
• #23 - user agent

Bug Fixes:

• #24 - fix racey reader IDENTIFY buffering
• #29 - fix recursive RLock deadlocks

0.3.4 - 2013-11-19

Upgrading from 0.3.3: There are no backward incompatible changes.

This is a bug fix release, notably potential deadlocks in Message.Requeue() and Message.Touch() as well as a potential busy loop cleaning up closed connections with in-flight messages.

New Features/Improvements:

• #14 - add Reader.Configure()
• #18 - return an exported error when an nsqlookupd address is already configured

Bug Fixes:

• #15 - dont let handleError() loop if already connected
• #17 - resolve potential deadlocks on Message responders
• #16 - eliminate busy loop when draining finishedMessages

0.3.3 - 2013-10-21

Upgrading from 0.3.2: This release requires NSQ binary version 0.2.23+ for compression support.

This release contains significant Reader refactoring of the RDY handling code paths. The motivation is documented in #1 however the commits in #8 identify individual changes. Additionally, we eliminated deadlocks during connection cleanup in Writer.

As a result, both user-facing APIs should now be considerably more robust and stable. Additionally, Reader should behave better when backing off.

New Features/Improvements:

• #9 - ability to ignore publish responses in Writer
• #12 - Requeue() method on Message
• #6 - Touch() method on Message
• #4 - snappy/deflate feature negotiation

Bug Fixes:

• #8 - Reader RDY handling refactoring (race conditions, deadlocks, consolidation)
• #13 - fix Writer deadlocks
• #10 - stop accessing simplejson internals
• #5 - fix max-in-flight race condition

0.3.2 - 2013-08-26

Upgrading from 0.3.1: This release requires NSQ binary version 0.2.22+ for TLS support.

New Features/Improvements:

• #227 - TLS feature negotiation
• #164/#202/#255 - add Writer
• #186 - MaxBackoffDuration of 0 disables backoff
• #175 - support for nsqd config option --max-rdy-count
• #169 - auto-reconnect to hard-coded nsqd

Bug Fixes:

• #254/#256/#257 - new connection RDY starvation
• #250 - nsqlookupd polling improvements
• #243 - limit IsStarved() to connections w/ in-flight messages
• #169 - use last RDY count for IsStarved(); redistribute RDY state
• #204 - fix early termination blocking
• #177 - support broadcast_address
• #161 - connection pool goroutine safety

0.3.1 - 2013-02-07

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

0.3.0 - 2013-01-07

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.

• #90 performance optimizations
• #81 reader performance improvements / MPUB support

0.2.4 - 2012-10-15

• #69 added IsStarved() to reader API

0.2.3 - 2012-10-11

• #64 timeouts on reader queries to lookupd
• #54 fix crash issue with reader cleaning up from unexpectedly closed nsqd connections

0.2.2 - 2012-10-09

• Initial public release
