Improvements and fixes

This update contains the following improvements in SharePoint Server 2016:

• Adds support for the new Japanese era name to the Chinese word breaker to make sure that the name will be broken correctly.
• Makes general improvements for notebooks that are located in folders that are synced through OneDrive.
  Contains fixes for the following nonsecurity issues in SharePoint Server 2016:
• You can‘t create a subsite based on a template that includes content in a site collection that has a retention policy.
• Query Builder takes a long time to load or times out if there are many managed properties (for example, more than 10 thousand) in the Search service application (SSA).
• Fixes an error when re-executing the backup and restore operations after executing the backup and restore operations with UI mode.
• Fixes an issue in which resetting the role inheritance by using the SPWeb.ResetRoleInheritance method does not work on copied sites that are created by using the Copy-SPSite cmdlet.
• In some cases, existing files are overwritten even if users don’t explicitly overwrite the files.
  Contains the following improvements and fixes for nonsecurity issues in Project Server 2016:
• Makes changes so that the first year of an era in Japanese dates on a timeline view shows as the special Kanji character (元). The Japanese date format is now consistent between the calendar date picker and the timeline view.
• You can now update a task dependency lead and lag time by using the LinkLagDurationproperty through the client-side object model (CSOM). Similar to other duration properties (such as the Task.Duration property in the Task Object),LinkLagDuration accepts either a string or an integer value, such as “1d” or “480” to indicate one day of work.
• After you change actual work values in a timesheet, you find that the columnar Total workvalues in the time-phased grid part of the view does not sum correctly.
• When you query project-level information through the client-side object model (CSOM), read performance is slow if the Project Owner field is included.
