New Restrictions 

  Availability Options Requirements Description
Allow Auto Unlock
  • iPhone
  • iPod
  • Enabled or Disabled
  • iOS 14.5
Prevents the usage of the auto unlock capability.
Allow NFC
  • iPhone
  • Enabled or Disabled
  • iOS 14.2
Users can’t use built-in NFC hardware in compatible devices running iOS 14.2 or later.
Allow Recovery Mode From an Unpaired Host
  • iPhone
  • iPod
  • iPad
  • Enabled or Disabled
  • iOS 14.5
  • iPadOS 14.5
iPhone, iPod touch, and iPad previously allowed any external host computer to start a device in Recovery Mode, which meant that the host computer could completely erase the device and restore the operating system. iOS 14.5 and iPadOS 14.5 now prevent this behavior by default.
Force On-Device Dictation
  • iPhone
  • iPod
  • iPad
  • Enabled or Disabled
  • iOS 14.5
  • iPadOS 14.5
You can use dictation instead of your keyboard to enter text with many apps and features that use the keyboard on your iPhone, iPad, or iPod touch running iOS 14.5 or iPadOS 14.5. This setting prevents dictated content from being sent to Siri servers for processing.
Force Managed Pasteboard 
  • iPhone
  • iPod
  • iPad
  • Enabled or Disabled
  • iOS 14.5
  • iPadOS 14.5
With Managed Pasteboard settings, Apple provides the ability to apply the same restrictions to the copy and paste functionality, meaning that information copied from corporate apps cannot be pasted in unmanaged apps and/or the reverse.

Apple Classroom Configuration

Classroom is a powerful app for iPad and Mac that helps you guide learning, share work, and manage student devices. ... You can launch a specific app, website, or textbook page on any iPad in the class, share documents between teacher and students, or share student work on a TV, monitor, or projector using Apple TV. With this Technical Release we introduce the Education Configuration with Silverback. This is the payload for configuring the users, groups, and departments within an educational organization.

Apple School Manager is still in an unsupported state. The Classroom configuration can be used without any Apple School Manager Integration.

Extension of Custom Profiles

Custom Profiles are a very helpful option to configure additional payloads for your managed devices. You can utilize the Apple Configurator 2 to create custom profiles in a *.mobileconfig format. You can easily open and edit these files by adjusting the file type to *.txt (e.g. on Windows 10) or opening these files directly with the Text Editor  (e.g. on macOS devices). With this new Silverback version we are supporting that System Variables can be entered either in the new Use XML or with uploading a *.mobileconfig file that contains a System Variable. Silverback will adjust the XML or the mobileconfig on the fly and convert the System Variables to the individiual input and install this payload with the desired content of the variable on your devices.
