Cut Prometheus 0.16.0rc1.

CHANGELOG.md

+## 0.16.0rc1 / 2015-09-XX
+
+BREAKING CHANGES:
+
+* Release tarballs now contain the built binaries in a nested directory.
+* The `hash_mod` relabeling action now uses MD5 hashes instead of FNV hashes to
+  achieve a better distribution.
+* The DNS-SD meta label `__meta_dns_srv_name` was renamed to `__meta_dns_name`
+  to reflect support for other record types than `SRV`.
+* The default full refresh interval for the file-based service discovery has been
+  increased from 30 seconds to 5 minutes.
+* In relabeling, parts of a source label that weren't matched by
+  the specified regular expression are no longer included in the replacement output.
+* Queries no longer interpolate between two data points. Instead, the resulting
+  value will always be the latest value before the evaluation query timestamp.
+* Regular expressions supplied via the configuration are now anchored to match
+  full strings instead of substrings.
+* Global labels are not appended upon storing time series anymore. Instead,
+  they are only appended when communicating with external systems
+  (Alertmanager, remote storages, federation).
+* The names and units of metrics related to remote storage sample appends have
+  been changed.
+* The experimental support for writing to InfluxDB has been updated to work
+  with InfluxDB 0.9.x. 0.8.x versions of InfluxDB are not supported anymore.
+
+All changes:
+
+* [CHANGE] Vendoring is now done via govendor instead of godep.
+* [CHANGE] Change web UI root page to show the graphing interface instead of
+  the server status page.
+* [CHANGE] Append global labels only when communicating with external systems
+  instead of storing them locally.
+* [CHANGE] Change all regexes in the configuration to do full-string matches
+  instead of substring matches.
+* [CHANGE] Remove interpolation of vector values in queries.
+* [CHANGE] For alert `SUMMARY`/`DESCRIPTION` template fields, cast the alert
+  value to `float64` to work with common templating functions.
+* [CHANGE] In relabeling, don't include unmatched source label parts in the
+  replacement.
+* [CHANGE] Change default full refresh interval for the file-based service
+  discovery from 30 seconds to 5 minutes.
+* [CHANGE] Rename the DNS-SD meta label `__meta_dns_srv_name` to
+  `__meta_dns_name` to reflect support for other record types than `SRV`.
+* [CHANGE] Release tarballs now contain the binaries in a nested directory.

+  discovery.
+* [FEATURE] Add `labelmap` relabeling action to map a set of input labels to a
+  set of output labels using regular expressions.

+  to not be used by Prometheus internally.
+* [FEATURE] Kubernetes-based service discovery.
