📋 Changes

• Add KOA middleware support
• [BREAKING] drops support for node 6

📋 Changes

• fix(signalfx): repeat word in log statement

📋 Changes

• feat(signalfx-reporter): add additional debug logging (#71)

📋 Changes

• feat: add metricLimit and lru to DimensionAwareMetricsRegistry (#69)

📦 Measured Reporting

• Added flag to indicate if metrics should be reset on each reporting interval.

✨ new `keepAlive` option on `Meter` and `Timer`

• `Meter` and `Timer` were using `setInterval` and keeping a ref to it as well keeping processes hanging. This can now be controlled via a new `keepAlive` option.

📦 Measured SignalFx Reporter

• The sendEvent wrapper now returns a promise.

📋 Changes

• Replaced the default logger in the loging reporter with one that doesn’t need to compile from source to prevent possible issues on Windows.

📋 Changes

• Updated express middleware to report statusCode and uri accurately for POST requests.

📋 Changes

• Defer initial report so it is not sent immediately when the first metric gets added

📋 Changes

• Added unrefTimers option, enabling interval timers to be unref'd, so the event loop can exit when there are no other ref'd handles.

📋 Changes

• Fixing runaway travis release config

📋 Changes

• Made libraries compatible with all maintained Node.js release lines.

📦 Measured Node Metrics

• Renamed the default middleware dimension of `path` to `uri` to match what other libs are doing, so that re-usable dashboards can be implemented with no regard to the underlying library that is supplying the metrics.

📦 Measured Reporting

• Fix bug where toLowerCase() could be called on undefined, in the Logging Reporter.

📦 Measured Core

• Fix #47 via PR #48 so that the expected and actual metrics type of a SettableGauge align when using the Collection registry in measured-core.

📦 Measured Reported

• Allow users to [control the log level](https://yaorg.github.io/node-measured/global.html#LoggingReporterOptions) at which metrics are logged at when using a [LoggingReporter](https://yaorg.github.io/node-measured/LoggingReporter.html).
• Allow users to use more than one [Reporter Implementation](https://yaorg.github.io/node-measured/Reporter.html) when using a [SelfReportingMetricsRegistry](https://yaorg.github.io/node-measured/SignalFxSelfReportingMetricsRegistry.html).

📦 Measured SignalFx Reporter

• Exposed the sendEvent API from the SignalFx client in the SignalFx Metrics Registry and Reporter classes

📦 Measured Reporting

• Added [LoggingReporter](http://yaorg.github.io/node-measured/LoggingReporter.html), a simple reporter that logs metrics via the logger implementation. Useful for local development and as a example reporter. Perhaps maybe even useful for applications that do not have a time series data aggregator such as Graphite, Datadog or SignalFx, but do have a log aggregation such as Splunk or Logstash.

📦 Measured Core and Measured Reporting

• Add get / create [CachedGauge](https://yaorg.github.io/node-measured/CachedGauge.html) method to registries.

📦 Measured Node Metrics

• Fix typo in requests metric name for node Middleware's.
• *If you made a dashboard using `request` you will have to update your dashboard to use `requests`*

📦 Measured Core

• Add new Gauge type called CahcedGauge based off of the [CachedGauge in the DropWizard Metrics Lib](https://github.com/dropwizard/metrics/blob/4.1-development/metrics-core/src/main/java/com/codahale/metrics/CachedGauge.java) for self updating and caching async metrics such as CPU Usage.

📦 Measured Node Metrics

• Add new package that exposes helper methods for generating default node metrics

📋 Changes

• Added initial release of the measured-reporting package, which has the classes needed to create self reporting dimension aware metrics registries. See: http://yaorg.github.io/node-measured/packages/measured-reporting/
• Added initial release of the measured-signalfx-reporter, which has the classes needed to create a registry that is able to report core metrics to SignalFx. See: http://yaorg.github.io/node-measured/packages/measured-signalfx-reporter/

📋 Changes

• Add MetricTypes as an export in the main module.

📋 Changes

• Add NoOpMeter, a meter that doesn't do anything, this is usful to use in a Timer if you want access to the Stopwatch api for histogram data and don't want to deal with the overhead of a meter.

📋 Changes

• Add SettableGauge, a gauge that can have it's value set directly, useful for async situations
• Converts Files to ES6, using modified AirBnB eslint rules.
• Remove documentation from README and annotated all the classes so that documentation is generated from code rather than manually curated.
• Add tasks to create documentation static html site
• Renamed `measured` package name to `@yaorg/measured-core` to reflect new org and the fact that it is the core library.
• Configure Travis to do npm releases when tags are published

📋 Changes

• Add Histogram#hasValues (@horte)

📋 Changes

• Add "files" list to package.json

📋 Changes

• Fix counter.inc(0) and counter.dec(0) (@mantoni)

📋 Changes

• Browserify support (@mantoni)
• Change test framework to Mocha and Mochify (@mantoni)
