Deprecated Features in the Platform - Clients, Server, and Database (2023 release wave 2)

License files in the .flf format for Business Central on-premises (Removal)

Importing license files in the .flf format will be unsupported in Business Central 2023 release wave 1. The format remains supported in older versions. Please transition to using the newer .bclicense format instead.

Business Central Server Administration tool (Removal)

The Business Central Server Administration tool for configuring the Business Central Server in on-premises installations will be removed in the 2022 release wave 2 (version 21.0). Please use the Windows PowerShell cmdlets that we make available in the Business Central Administration Shell instead.

Behavior of promoted action groups

When the Modern Action Bar on the Feature Management page is set to Enabled, promoted actions, which are defined inside a group whose visibility is set to false will no longer be visible on the promoted side of the action bar. A dedicated code analysis rule in the UICop analyzer (AW0013) helps detect this pattern in your apps. For more information, see UICop Warning AW0013. For more information about the actionref syntax, see Promoted Actions.
