This public update also delivers all the features that were included in Feature Pack 1 for SharePoint Server 2016, including:

Improvements and fixes

This security update enables the Search administrator to use the case-insensitive crawl behavior instead of case-sensitive crawling by setting the CaseSensitiveUrls property to 0. To do this, use the following PowerShell script:

$ssa = Get-SPEnterpriseSearchServiceApplication
$ssa.SetProperty("CaseSensitiveUrls", 0)
$ssa.Update()

This update also contains fixes for the following nonsecurity issues in Project Server 2016:
