# Ohai Release Notes 14.0
## Windows Kernel information
The kernel plugin now reports the following information on Windows:
- `node['kernel']['product_type']` - Workstation vs. Server editions of Windows
- `node['kernel']['system_type']` - What kind of hardware are we installed on (Desktop, Mobile, Workstation, Enterprise Server, etc.)
- `node['kernel']['server_core']` - Are we on Windows Server Core edition?
## Cloud Detection
Ohai now detects the Scaleway cloud and provides additional configuration information for systems running on Azure.
## Virtualization / Container Detection
In addition to detecting if a system is a Docker host, we now provide a large amount of Docker configuration information available at `node['docker']`. This includes the release of Docker, installed plugins, network config, and the number of running containers.
Ohai also now properly detects LXD containers and macOS guests running on VirtualBox / VMware. This data is available in `node['virtualization']['systems']`
## Optional Ohai Plugins
Ohai now includes the ability to mark plugins as optional, which skips those plugins by default. This allows us to ship additional plugins, which some users may find useful, but not all users would want being written to their Chef server. The change introduces two new configuration options; `run_all_plugins` which runs everything including optional plugins, and `optional_plugins` which allows you to run plugins marked as optional.
By default we will now be marking the `lspci`, `sessions` and `passwd` plugins as optional. Passwd has been particularly problematic for nodes attached LDAP or AD where it attempts to write the entire directory to the node. If you previously disabled this plugin via Ohai config, you no longer need to. Hurray!
## Logging Improvements
Chef and Ohai now includes a new log level of `:trace` in addition to the existing `:info`, `:warn`, and `:debug` levels. With the introduction of `trace` level logging we've moved a large amount of logging that more useful for developers from `debug` to `trace`. If you want a complete insight into what is going on internally in Ohai run -l trace not -l debug.
## Breaking Changes
### cloud_v2 and filesystem2 Plugins
In Chef 13 the `cloud_v2` plugin replaced data at `node['cloud']` and `filesystem2` replaced data at `node['filesystem']`. For compatibility with cookbooks that were previously using the "v2" data we continued to write data to both locations (ie: both node['filesystem'] and node['filesystem2']). We now no longer write data to the "v2" locations which greatly reduces the amount of data we need to store on the Chef server.
### Ipscopes Plugin Removed
The ipscopes plugin has been removed as it duplicated data already present in the network plugins and required the user to install an additional gem into the Chef installation.
### libvirt attributes moved
The libvirt Ohai plugin now writes data to `node['libvirt']` instead of writing to various locations in `node['virtualization']`. This plugin required installing an additional gem into the Chef installation and thus was infrequently used.
### Ohai Plugin V6 Support Removed
In 2014 we introduced Ohai v7 with a greatly improved plugin format. With Chef 14 we no longer support loading of the legacy "v6" plugin format.
### Newly-disabled Ohai Plugins
As mentioned above we now support an `optional` flag for Ohai plugins and have marked the `sessions`, `lspci`, and `passwd` plugins as optional, which disables them by default. If you need one of these plugins you can include them using `optional_plugins`.
optional_plugins in the client.rb file:
```ruby
optional_plugins [ "lspci", "passwd" ]
```
# Ohai Release Notes 13.8.0
## Softlayer metadata polling fixed
We now use TLS 1.2 for polling Softlayer metadata since 1.0/1.1 were disabled on 3/1/2018
# Ohai Release Notes 13.7.1
## Network Tunnel Information
The Network plugin on Linux hosts now gathers additional information on tunnels
## LsPci Plugin
The new LsPci plugin provides a `node[:pci]` hash with information about the PCI bus based on `lspci`. Only runs on Linux.
# Ohai Release Notes 13.7
## EC2 C5 Detection
The EC2 plugin has been updated to properly detect the new AWS hypervisor used in the C5 instance types
## mdadm
The mdadm plugin has been updated to properly handle arrays with more than 10 disks and to properly handle journal and spare drives in the disk counts
# Ohai Release Notes 13.6
## Critical Plugins
Users can now specify a list of plugins which are `critical`. Critical plugins will cause Ohai to fail if they do not run successfully (and thus cause a Chef run using Ohai to fail). The syntax for this is:
```
ohai.critical_plugins << :Filesystem
```
## Filesystem now has a `allow_partial_data` configuration option
The Filesystem plugin now has a `allow_partial_data` configuration option. If set, the filesystem will return whatever data it can even if some commands it ran failed.
## Rackspace detection on Windows
Windows nodes running on Rackspace will now properly detect themselves as running on Rackspace without a hint file.
## Package data on Amazon Linux
The Packages plugin now supports gathering packages data on Amazon Linux
## Deprecation updates
In Ohai 13 we replaced the filesystem and cloud plugins with the filesystem2 and cloud_v2 plugins. To maintain compatibility with users of the previous V2 plugins we write data to both locations. We had originally planned to continue writing data to both locations until Chef 15\. Instead due to the large amount of duplicate node data this introduces we are updating OHAI-11 and OHAI-12 deprecations to remove node['cloud_v2'] and node['filesystem2'] with the release of Chef 14 in April 2018.
# Ohai Release Notes 13.5
## Correctly detect IPv6 routes ending in ::
Previously we would ignore routes that ended `::`, and now we properly detect them.
## Plugin run time is now measured
Debug logs will show the length of time each plugin takes to run, making debugging of long ohai runs easier.
# Ohai Release Notes 13.4
## Windows EC2 Detection
Detection of nodes running in EC2 has been greatly improved and should now detect nodes 100% of the time including nodes that have been migrated to EC2 or were built with custom AMIs.
## Azure Metadata Endpoint Detection
Ohai now polls the new Azure metadata endpoint, giving us additional configuration details on nodes running in Azure
Sample data now available under azure:
```javascript

"compute": {
"location": "westus",

}
}
}
```
## Package Plugin Supports Arch Linux
The Package plugin has been updated to include package information on Arch Linux systems.
# Ohai Release Notes 13.3
## Additional Platform Support
Ohai now properly detects the [F5 Big-IP](https://www.f5.com/) platform and 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.
