platform_version.
- platform: bigip
- platform_family: rhel
# Ohai Release Notes 13.2:
Ohai 13.2 has been a fantastic release in terms of community involvement with
new plugins, platform support, and critical bug fixes coming from community
members. A huge thank you to msgarbossa, albertomurillo, jaymzh, and davide125
for their work.
## New Features
### Systemd Paths Plugin
A new plugin has been added to expose system and user paths from systemd-path
(see <https://www.freedesktop.org/software/systemd/man/systemd-path.html> for
details).
### Linux Network, Filesystem, and Mdadm Plugin Resilience
The Network, Filesystem, and Mdadm plugins have been improved to greatly
reduce failures to collect data. The Network plugin now better finds the
binaries it requires for shelling out, filesystem plugin utilizes data from
multiple sources, and mdadm handles arrays in bad states.
### Zpool Plugin Platform Expansion
The Zpool plugin has been updated to support BSD and Linux in addition to
Solaris.
### RPM version parsing on AIX
The packages plugin now correctly parses RPM package name / version
information on AIX systems.
### Additional Platform Support
Ohai now properly detects the [Clear](https://clearlinux.org/) and
[ClearOS](https://www.clearos.com/) Linux distributions.
#### Clear Linux
- platform: clearlinux
- platform_family: clearlinux
#### ClearOS
- platform: clearos
- platform_family: rhel
## New Deprecations
### Removal of IpScopes plugin. (OHAI-13)
<https://docs.chef.io/deprecations_ohai_ipscopes.html>
In Chef/Ohai 14 (April 2018) we will remove the IpScopes plugin. The data
returned by this plugin is nearly identical to information already returned by
individual network plugins and this plugin required the installation of an
additional gem into the Chef installation. We believe that few users were
installing the gem and users would be better served by the data returned from
the network plugins.

Ohai detects data about your operating system. It can be used
standalone, but it's primary purpose is to provide node data to Chef.
Ohai will print out a JSON data blob for all the known data about your
system. When used with Chef, that data is reported back via node
attributes.
