May 3, and Raspberry Pi has released the latest update for its long-running Raspberry Pi OS. Coming two months after the previous release, this time we see bug fixes, a new Linux kernel and updates to common software.

- Linux kernel 6.1.21
The May 3 update is more of a maintenance release, with nothing major changing apart from an updates Linux kernel. Moving from 5.15.84 to 6.1.21, both of which are long-term maintenance kernels, often used for bugfixes. Other than that we see a handful of bugfixes and updates for applications. Software libraries for Raspberry Pi camera hardware also sees an update to further refine the user experience.
Other key app updates are for Chromium, the default web browser, Mathematica, Matlab and RealVNC. VLC, the well known video player receives a hardware acceleration patch.
Behind the scenes, and the other key software updates are for the Raspberry Pi camera ecosystem. Libcamera, a means to use cameras, including the Raspberry Pi cameras via the terminal has a number of updates for improved performance, overflow fixes and improved IMX296 sensor tuning. The IMX296 is the sensor used in the Global Shutter Camera. The Pythonic means to work with the Raspberry Pi cameras is picamera2, and this also sees a few updates and bugfixes to improve H264 encoding and EXIF data tags.
Lastly we see a few bugfixes for the OS itself, one for a segfault in the CPU temperature plugin and two for X server (screen rotation and Display Power Management Signalling).
The updated Raspberry Pi OS will work with all models of Raspberry Pi, from the original 256MB Model B in 2012, all the way to the Raspberry Pi 4 Model B. It can be installed using Raspberry Pi Imager, or by directly downloading the image and using a tool such as Etcher / Rufus to write the image.
