+## New FastMSI omnibus installer (Windows)
+
+This is the first release where we are rolling out a MSI package for Windows that significantly improves the installation time. In a nutshell, the new approach is to deploy and extract a zipped package rather than individually tracking every file as a MSI component. Please note that the first  upgrade (ie, an older version of Chef client is already on the machine) may not exhibit the full extent of the speed-up (as MSI is still tracking the older files). New installs, as well as future upgrades, will be sped up. Uninstalls will remove the folder that Chef client is installed to (typically, C:\Opscode\Chef).

 ## Better handling of log_location with chef client service (Windows)
 
 This change is for the scenario when running chef client as a Windows service. Currently, a default log_location gets used by the chef client windows service. This log_location overrides any log_location set in the client.rb. In 12.6.0, the behavior is changed to allow the Chef client running as a Windows service to prefer the log_location in client.rb instead. Now, the windows_service_manager will not explicitly pass in a log_location, and therefore the Chef service will always use what is in the client.rb or the typical default path if none is configured. This enables scenarios such as logging to the Windows event log when running chef client as a Windows service.

+## Dsc_resource changes and fixes (Windows)
 
 * A fix was made for the Nov 2015 update of Windows 10, where the dsc_resource did not properly show the command output when converging the resource.
 * Dsc_resource could in some cases show the plaintext password when #inspected - this is now prevented from happening.
-* Previously, Chef required the LCM Refreshmode to be set to Disabled when utilizing dsc_resource. Microsoft has relaxed this requirement in WFM 5 (PowerShell 5.0.10586.0 or later).  Now, we only require the RefreshMode to be disabled when running on earlier versions of PowerShell.

Now, we only require the RefreshMode to be disabled when running on earlier versions of PowerShell 5.
 * Added a 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.
