[Unreleased]

[0.12.0] - 2019-10-18

Changed

Rename Sink::record_counter to increment_counter, Sink::record_gauge to update_gauge. (#47)
Rename Receiver::get_controller and Receiver::get_sink to controller and sink, respectively. (#48)
Switch to the new updated Recorder trait from metrics. (#47)

Fixed

Fixed some broken tests and incorrect documentation. (#53)

[0.11.0] - 2019-07-29

Added

Metrics now support labels. (#27)
Add support for proxy metrics. (#39)

Changed

metrics becomes metrics-runtime after switching the runtime and the facade crate. (#27)
Switch from "recorders" to "observers." (#35)

[0.10.0] - 2019-06-11

Changed

Entirely remove the event loop and switch to pure atomics. (#13)

[0.9.1] - 2019-05-01

Added

Expose exporters/recorders via a facade module in metrics. (#8)

[0.9.0] - 2019-04-03

Changed

hotmic is renamed to `metrics. (#2)

[0.8.2] - 2019-03-19

Added

Histograms now track the sum of all values they record, to support target systems like Prometheus.
Added the ability to get percentiles as quantiles. This is also to support target systems like Prometheus. These are derived from the existing percentile values and so can have extra decimal precision. This will be unified in a future breaking update.

[0.8.1] - 2019-03-15

Changed

Fixed some issues with type visibility and documentation.

[0.8.0] - 2019-03-15

Changed

Removed accessors from Snapshot. It is not an opaque type that can be turned into an iterator which will provide access to typed metric values so that an external consumer can get all of the values in the snapshot, including their type, for proper exporting.

Added

A new "simple" snapshot type -- SimpleSnapshot -- which has easy-to-use accessors for metrics, identical to what Snapshot used to have.
Allow retrieving snapshots asynchronously via Controller::get_snapshot_async. Utilizes a oneshot channel so the caller can poll asynchronously.

[0.7.1] - 2019-01-28

Changed

Fixed a bug where new sinks with the same scope would overwrite each others metrics. #20

[0.7.0] - 2019-01-27

Changed

Sink scopes can now be either a &str or &[&str].
Fixed a bug where the receiver loop ran its thread at 100%.

Changed

Metrics auto-register themselves now. #16
