NOTE: This release breaks backward compatibility. `statsd_exporter` now uses
a YAML configuration file. You must convert your mappings configuration to
the new format when you upgrade.
the new format when you upgrade. For example, the configuration
* [CHANGE] Use YAML for configuration file
* [BUGFIX] Fix matching empty statsd metric components #105
* [CHANGE] Reduce log levels #92
* [CHANGE] Removed `-statsd.add-suffix` option flag #99
```

action="$2"
outcome="$3"
job="test_dispatcher"
*.signup.*.*
name="signup_events_total"
provider="$2"
outcome="$3"
job="${1}_server"
```
now has the format
```yaml
mappings:
- match: test.dispatcher.*.*.*
help: "The total number of events handled by the dispatcher."
name: "dispatcher_events_total"
labels:
processor: "$1"
action: "$2"
outcome: "$3"
job: "test_dispatcher"
- match: *.signup.*.*
name: "signup_events_total"
help: "The total number of signup events."
labels:
provider: "$2"
outcome: "$3"
job: "${1}_server"
```
The help field is optional.
There is a [tool](https://github.com/bakins/statsd-exporter-convert) available to help with this conversion.
* [CHANGE] Replace the overloaded "packets" metric (#106)
* [CHANGE] Removed `-statsd.add-suffix` option flag #99. Users should remove
this flag wgen upgrading. Metrics will no longer automatically include the
suffixes "_timer" or "counter". You may need to adjust any graphs that used
metrics with these suffixes.
* [CHANGE] Reduce log levels #92. Many log events have been changed from error
to debug log level.
* [CHANGE] Use YAML for configuration file #66. See note above about file format
conversion.
* [IMPROVEMENT] Allow help text to be customized #87
* [IMPROVEMENT] Add support for regex mappers #85
* [BUGFIX] Fixes for crashes with conflicting metric values #72
* [IMPROVEMENT] Add TCP listener support #71
* [IMPROVEMENT] Allow histograms for timer metrics #66
* [IMPROVEMENT] Added support for sampling factor on timing events #28
* [BUGFIX] Conflicting label sets no longer crash the exporter and will be
ignored. Restart to clear the remembered label set. #72
