The latest update to the Raspberry Pi OS introduces a host of new desktop extensions that improve access to text-based search, network management, and the Pi’s camera system.
The Raspberry Pi OS also adds a new text-based search box for searching apps such as File Manager, OS Imager, and Image Viewer. It can be accessed by pressing the Raspberry key on your keyboard or the Windows key on other keyboards. The existing menu remains unchanged.
There is also an audio icon for output and another icon for input. Also, when you connect a USB or Bluetooth audio device, you will see a microphone icon.
New shortcuts include Ctrl-Alt-B to open the Bluetooth menu and Ctrl-Alt-W to open the Wi-Fi menu.
This release includes the popular NetworkManager software in other Linux distributions for Wi-Fi network management. Until now, Pi OS used dhcpcd to manage connections to Wi-Fi networks. NetworkManager is another option that the user has to enable in his default dhcpcd. However, it will become the default in the future. Connections are not automatically handed over between the two systems. Users will also need to reconfigure their network customizations.
“The main reason for switching is that NetworkManager adds a lot of useful extra features. You can hide the SSID and easily connect to wireless networks. It makes VPN connections easier to manage. Also, the Raspberry Pi You can easily configure it as a Wi-Fi access point,” explains Simon Long of Raspberry Pi.

In-house development/open source python piccamera 2 The camera interface is now shipped with the OS. This library is based on the existing libcamera framework but made easier to use. Replaces the old Picamera library. Deprecated in Debian Bullseye release of Pi OS.
Raspberry Pi Engineer David Plowman I will explain In this case, the Pi OS platform is moving away from Broadcom’s proprietary closed camera API. Raspberry Pi devices running on Broadcom silicon Shipped in binary blobs contains its own code, Annoyed some open source fans.
This is a beta release of Picamera2 that allows developers to use AI frameworks such as Tensorflow for image analysis and detection.
Picamera2 is installed with dependencies Qt and OpenGL. However, these dependencies are not installed on the Raspberry Pi OS Lite for low power devices as they struggle with X Windows based applications.
According to the Raspberry Pi, the main features besides video encoding, recording and drawing overlay are:
- Command driven paradigm. This means you can type Picamera2 commands directly into the Python interpreter or Python script.
- Preview window with OpenGL acceleration for hardware-assisted rendering or DRM/KMS for efficient rendering when X Windows is not running
- Additional support for embedding off-the-shelf Picamera2 widgets into Qt applications
- Native use of numpy. “It makes working with OpenCV, TensorFlow, and other Python libraries very natural.”
