**Upgrading** * #1055 - `nsqd`: removed support for old metadata scheme used in v0.3.8 and earlier * you cannot upgrade directly from v0.3.8 to v1.2.0, you must go through v1.0.0-compat or v1.1.0 * #1115 - manage dependencies with go modules * `dep` support still present for now, but deprecated Features: * #1136 - `nsqd`: add `--max-channel-consumers` (default unlimited) (thanks @andyxning) * #1133 - `nsqd`: add `--min-output-buffer-timeout` (default 25ms) to limit how low a timeout a consumer can request * and raise default `--max-output-buffer-timeout` to 30 seconds (lower timeout, more cpu usage) * #1127 - `nsqd`: add topic total message bytes to stats (thanks @andyxning) * #1125 - `nsqd`: add flag to adjust default `--output-buffer-timeout` (thanks @andyxning) * #1163 - `nsqd`: add random load balancing for authd requests (thanks @shenhui0509) * #1119 - `nsqd`: include client TLS cert CommonName in authd requests * #1147 - `nsq_to_file`: include topic/channel in most log messages * #1117 - `nsq_to_file`: add `--log-level` and `--log-prefix` flags * #1117/#1120/#1123 - `nsq_to_file`: big refactor, more robust file switching and syncing an

**Upgrading from 1.0.0-compat**: Just a few backwards incompatible changes: * #1056 - Removed the `nsq_pubsub` utility * #873 - `nsqd` flags `--msg-timeout` and `--statsd-interval` only take duration strings * plain integer no longer supported * #921 - `nsqd`: http `/mpub` endpoint `binary` param interprets "0" or "false" to mean text mode * previously any value meant to use binary mode instead of text mode - (thanks @andyxning) The previous release, version "1.0.0-compat", was curiously-named to indicate an almost (but not quite) complete transition to a 1.0 api-stable release line. Confusingly, this follow-up release which completes the transition comes more than a year later. Because there have been a fair number of changes and improvements in the past year, an additional minor version bump seems appropriate. Features: * #874 - `nsqd`: add memory stats to http `/stats` response (thanks @sparklxb) * #892 - `nsqd`, `nsqlookupd`, `nsqadmin`: add `--log-level` option (deprecating `--verbose`) (thanks @antihax) * #898 - `nsqd`, `nsqlookupd`, `nsqadmin`: logging refactor to use log levels everywhere * #914 - `nsqadmin`: `X-Forwarded-User` based "admin"

See release [v1.1.0](https://github.com/nsqio/nsq/releases/tag/v1.1.0)

**Upgrading from 0.3.8**: Numerous backwards incompatible changes: * Deprecated `nsqd` features removed: * Pre-V1 HTTP endpoints / response format: * `/{m,}put` (use `/{m,}pub`) * `/{create,delete,empty,pause,unpause}_{topic,channel}` (use `/{topic,channel}/<operation>`) * `--max-message-size` flag (use `--max-msg-size`) * `V2` protocol `IDENTIFY` command `short_id` and `long_id` properties (use `client_id`, `hostname`, and `user_agent`) * `/stats` HTTP response `name` property (use `client_id`) * Deprecated `nsqlookupd` features removed: * Pre-V1 HTTP endpoints / response format: * `/{create,delete}_{topic,channel}` (use `/{topic,channel}/<operation>`) * `/tombstone_topic_producer` (use `/topic/tombstone`) * Deprecated `nsqadmin` features removed: * `--template-dir` flag (not required, templates are compiled into binary) * `--use-statsd-prefixes` flag (use `--statsd-counter-format` and `--statsd-gauge-format`) * `nsq_stat` `--status-every` flag (use `--interval`) * `--reader-opt` on all binaries that had this flag (use `--consumer-opt`) * `nsq_to_file` `--gzip-compression` flag (use `--gzip-level`) * `nsq_to_http`

**Upgrading from 0.3.7**: Binaries contain no backwards incompatible changes. This release fixes a critical regression in `0.3.7` that could result in message loss when attempting to cleanly shutdown `nsqd` by sending it a `SIGTERM`. The expected behavior was for it to flush messages in internal buffers to disk before exiting. See #757 and #759 for more details. A few performance improvements landed including #743, which improves channel throughput by ~17%, and #740, which reduces garbage when reading messages from disk. We're now stripping debug info, reducing binary size, in the official binary downloads and Windows binaries are now bundled with the appropriate `.exe` extension (#726 and #751). Features: - #743 - `nsqd`: remove channel `messagePump` - #751 - strip debug info from binaries (thanks @ploxiln) - #740 - `nsqd`: reduce garbage when reading from diskqueue (thanks @dieterbe) Bugs: - #757/#759 - `nsqd`: properly handle `SIGTERM` (thanks @judwhite) - #738 - updates for latest `go-options` - #730 - `nsqd`: diskqueue sync count on both read/write - #734 - `nsqadmin`: make `rate` column work without `--proxy-graphite` (thanks @ploxiln) - #726 - add `.exe` extension to Wi

**Upgrading from 0.3.6**: Binaries contain no backwards incompatible changes. This release has been built with Go 1.6. Highlights include the various work done to reduce `nsqd` lock contention, significantly improving the impact of high load on the `/stats` endpoint, addressing issues with timeouts and failures in `nsqadmin` (#700, #701, #703, #709). Thanks to @judwhite, `nsqd` and `nsqlookupd` now natively support being run as a Windows service (#718). We're also now publishing official Windows releases. `nsqd` will now `flock` its data directory on linux, preventing two `nsqd` from running simultaneously pointed at the same path (#583). On the bugfix side, the most noteworthy change is that `nsqd` will now correctly reset health state on a successful backend write (#671). Features: - #700/#701/#703/#709 - `nsqd`: reduce lock contention (thanks @zachbadgett @absolute8511) - #718 - `nsqd`/`nsqlookupd`: support running as a windows service (thanks @judwhite) - #706 - `nsqd`: support enabling/disabling block profile via HTTP (thanks @absolute8511) - #710 - `nsqd`: support `POST` `/debug/pprof/symbol` (thanks @absolute8511) - #662 - `nsqadmin`: add flags for formatting statsd ke

**Upgrading from 0.3.5**: Binaries contain no backwards incompatible changes. We've adopted the [Contributor Covenant 1.2 Code of Conduct](CODE_OF_CONDUCT.md) (#593). Help us keep NSQ open and inclusive by reading and following this document. We closed a few longstanding issues related to `nsqadmin`, namely (#323, et al.) converting it to an API and single-page app (so that it is _much_ easier to develop), displaying fine-grained errors (#421, #657), and enabling support for `--tls-required` configurations (#396). For `nsqd`, we added support for deferred publishing aka `DPUB` (#293), which allows a producer to specify a duration of time to delay initial delivery of the message. We also addressed performance issues relating to large numbers of topics/channels (#577) by removing some per-channel goroutines in favor of a centralized, periodic, garbage collection approach. In order to provide more flexibility when deploying NSQ in dynamically orchestrated topologies, `nsqd` now supports the ability to configure `nsqlookupd` peers at runtime via HTTP (#601), eliminating the need to restart the daemon. As part of the large `nsqadmin` refactoring, we took the opportunity to cleanup

**Upgrading from 0.3.4**: Binaries contain no backwards incompatible changes. This is another quick bug fix release to address the broken `nsqadmin` binary in the `v0.3.4` distribution (see #578). See the release notes for [v0.3.3](https://github.com/bitly/nsq/releases/v0.3.3) for more info.
