Description of the required change.
-->
-### `chef_version` and `ohai_version`
+## Doc changes for Chef 12.9
-see: https://docs.chef.io/release/12-6/release_notes.html#new-metadata-rb-settings
+### New timeout option added to `knife ssh`
-The metadata.rb DSL is extended to support `chef_version` and `ohai_version` to establish ranges
-of chef and ohai versions that the cookbook supports.
+When doing a `knife ssh` call, if a connection to a host is not able
+to succeed due to host unreachable or down, the entire call can hang. In
+order to prevent this from happening, a new timeout option has been added
+to allow a connection timeout to be passed to the underlying SSH call
+(see ConnectTimeout setting in http://linux.die.net/man/5/ssh_config)
-When the running chef or ohai version does not match, then the chef-client run will abort with an
-exception immediately after cookbooks have been synchronized before any cookbook contents are
-parsed.
-
-The format of the dependencies is based on rubygems (and implemented with rubygems code). Pessimistic
-version constraints, floor and ceiling constraints, and specifying multiple constraints are all valid.
-
-Examples:
-
-```
-# matches any 12.x version, but not 11.x or 13.x
-chef_version "~> 12"
-```
-
-```
-# matches any 12.x, 13.x, etc version
-chef_version ">= 12"
-```
-
-```
-# matches any chef 12 version >= 12.5.1 or any chef 13 version
-chef_version ">= 12.5.1", "< 14.0"
-```
-
-```
-# matches chef 11 >= 11.18.4 or chef 12 >= 12.5.1 (i.e. depends on a backported bugfix)
-chef_version ">= 11.18.12", "< 12.0"
-chef_version ">= 12.5.1", "< 13.0"
-```
-
-As seen in the last example multiple constraints are OR'd.
-
-There is currently no support in supermarket for making this metadata visible in /universe to
-depsolvers, or support in Berksfile/PolicyFile for automatically pruning cookbooks that fail
-to match.
-
-### `ksh` resources
-
-Use the ksh resource to execute scripts using the Korn shell (ksh) interpreter.
-This resource may also use any of the actions and properties that are available
-to the execute resource.
-
-Example:
-```ruby
-ksh 'hello world' do
- code <<-EOH
- echo "Hello world!"
- echo "Current directory: " $cwd
- EOH
-end
-```
-
-See https://docs.chef.io/release/12-6/resource_ksh.html for more info.
-
-### `dsc_resource` resource
-
-Added reboot_action attribute to dsc_resource.
-
-If the DSC resource indicates that it requires a reboot, reboot_action can use the reboot resource to
-either reboot immediately (:reboot_now) or queue a reboot (:request_reboot). The default value of reboot_action is :nothing.
-
-The following two items in the dsc_resource doc in Chef 12.6.0 are ONLY applicable for PowerShell versions earlier than 5.0.10586.0. The latest version of WMF 5 has relaxed the limitation that prevented us from running in non-disabled RefreshMode configuration, and including both dsc_script and dsc_resource in the same run list:
-1. The RefreshMode configuration setting in the Local Configuration Manager must be set to Disabled
-2. The dsc_script resource may not be used in the same run-list with the dsc_resource. This is because the dsc_script resource requires that RefreshMode in the Local Configuration Manager be set to Push, whereas the dsc_resource resource requires it to be set to Disabled
-
-
-### `knife bootstrap --ssh-identity-file`
-
-The --identity-file option to `knife bootstrap` has been deprecated in favor of `knife bootstrap --ssh-identity-file`
-to better align with other ssh related options.
-
-### `windows_package` resource
-
-`windows_package` now supports more than just `MSI`. Most common windows installer types are supported including Inno Setup, Nullsoft, Wise and InstallShield. The new allowed `installer_type` values are: `inno`, `nsis`, `wise`, `installshield`, `custom`, and `msi`.
-
-**Non `:msi` package installation**
-When installing non `:msi` packages, the `package_name` should match the display name used for the installed package in the "Add/Remove Programs" settings application. This value can also be found in the following registry locations:
-* HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
-* HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
-* HKEY_LOCAL_MACHINE\Software\Wow6464Node\Microsoft\Windows\CurrentVersion\Uninstall
-
- Further, non `:msi` packages must explicitly include a package `source` attribute when using the `:install` action. Unlike `:msi` packages, they will not default to the package name if missing. Without the name matching the software's display name, non `:msi` packages will always reconverge on `:install`.
-
-Also, while being able to download remote installers from a `HTTP` resource is not new, it looks as though the top of the docs page is incorrect stating that only local installers can be used as a source.
-
-Example Nullsoft (`nsis`) package resource:
-```
-package 'Mercurial 3.6.1 (64-bit)' do
- source 'http://mercurial.selenic.com/release/windows/Mercurial-3.6.1-x64.exe'
- checksum 'febd29578cb6736163d232708b834a2ddd119aa40abc536b2c313fc5e1b5831d'
-end
-```
-
-Example Custom `windows_package` resource:
-```
-package 'Microsoft Visual C++ 2005 Redistributable' do
- source 'https://download.microsoft.com/download/6/B/B/6BB661D6-A8AE-4819-B79F-236472F6070C/vcredist_x86.exe'
- installer_type :custom
- options '/Q'
-end
-```
-Using a `:custom` package is one way to install a non `.msi` file that embeds an `msi` based installer.
-
-**`windows_package` removal**
-Packages can now be removed without the need to include the package `source`. The relevent uninstall metadata will now be discovered from the registry.
-```
-package 'Mercurial 3.6.1 (64-bit)' do
- action :remove
-end
-```
-For non `:msi` packages, it is important that the package name used is EXACTLY the same as the display name found in "Add/Remove programs" or the `DisplayName` property in the appropriate registry key:
-* HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
-* HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall
-* HKEY_LOCAL_MACHINE\Software\Wow6464Node\Microsoft\Windows\CurrentVersion\Uninstall
-
-When removing `:msi` packages, this same package naming rule applies if the `source` is omitted.
-
-Note that if there are multiple versions of a package installed with the same display name, all packages will be removed unless a version is provided in the `version` attribute or can be discovered in the `source` installer file.
+The timeout setting can be passed in via a command line parameter
+(`-t` or `--ssh-timeout`) or via a knife config
+(`Chef::Config[:knife][:ssh_timeout]`). The value of the timeout is set
+in seconds.
