-## master
+## v0.15.0 / 2017-10-06
 
-* [CHANGE] `node_cpu` metrics moved from `stats` to `cpu` collector on linux (enabled by default).
+**Breaking changes**
+
+This release contains major breaking changes to flag handling.
+* The flag library has been changed, all flags now require double-dashs. (`-foo` becomes `--foo`).
+* The collector selection flag has been replaced by individual boolean flags.
+* The `-collector.procfs` and `-collector.sysfs` flags have been renamed to `--path.procfs` and `--path.sysfs` respectively.
+
+The `ntp` collector has been replaced with a new NTP-based check that is designed to expose the state of a localhost NTP server rather than provide the offset of the node to a remote NTP server.  By default the `ntp` collector is now locked to localhost.  This is to avoid accidental spamming of public internet NTP pools.
+
+Windows support is now removed, the [wmi_exporter](https://github.com/martinlindhe/wmi_exporter) is recommended as a replacement.
