## master / unreleased
**Breaking changes**
Linux node_cpu metrics now break out `guest` values into separate metrics. See Issue #737
## v0.15.0 / 2017-10-06
**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* The collector selection flag has been replaced by individual boolean flags.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.
