## 0.15.0rc1 / 2015-06-24
BREAKING CHANGES:
- The default storage directory has been changed from `/tmp/metrics` to `data`
in the local directory.
- The `rule_checker` tool has been replaced by `promtool` with different flags and more functionality.
- Empty labels are now removed upon ingestion into the storage. Matching empty labels is
now equivalent to matching unset labels (`mymetric{label=""}` now matches
series that don't have `label` set at all).
- If you are using Consul for service discovery, it will now choose Consul's
`ServiceAddress` field for the instance address instead of the `Address`
field, if it is present.
- The special `__meta_consul_tags` label in Consul service discovery now
starts and ends with tag separators to enable easier regex matching.
- The default scrape interval has been changed back from 1 minute to 10 seconds.
