Note To apply this security update, you must have the release version of Microsoft SharePoint Enterprise Server 2016 installed on the computer.

This public update delivers Feature Pack 2 for SharePoint Server 2016. Feature Pack 2 contains the following feature:

SharePoint Framework (SPFx)

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

Administrative Actions Logging

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues in SharePoint Server 2016:

Adds support for the SameSite cookie attribute to remain compatible with changes in how web browsers such as Chrome handle cookies.
When a list view uses GroupBy on a calculated DateTime field and includes a multi-valued lookup field, users can't expand any of the groups in the view. A "working on it" message appears where the group should be expanded, and an error dialog box appears. After this update is applied, the issue is fixed.
After you create an enterprise custom field, the keyboard focus doesn't land on the next interactive element after you activate the Select value button.
After you import an updated thesaurus into the Search Service Application, you may see a "something went wrong" error message when you search from the Search box.
When you copy items that are declared as records through Windows Explorer, the copied items keep the record declaration status. This update fixes this issue.
When a user opens multiple SharePoint links on multiple browser tabs, enters credentials in one of the tabs, and then refreshes the other tabs, the sign-in process doesn't occur seamlessly. Instead, the user is redirected to the root site and not actual site.
Site collection level mappings do not occur for Default.aspx in each site's page library because the SiteId for Default.aspx is not generated correctly. After the fix is installed, the customized schema in site collection level will become active for default.aspx.

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

In Project Web App (PWA), you can't edit in a lookup table's Value and Description columns while you use the Chrome browser.
You edit a resource in Project Web App and use the Chrome browser. In this situation, although initials may exist for a work resource that's tied to a Windows user account, the Initials field isn't populated and appears blank. Therefore, if the resource is saved, the blank initials are saved over the correct initials.
You can't navigate through the tables on the Approvals and Resource pages by using a keyboard.
