Specifically, the site saw a 3-4C drop in temps with the new firmware. That may not sound like much, but performance also improved, as the Raspberry Pi 4 did not throttle as quickly.

If you've been 3D printing for a while, you might have heard of Klipper. This custom firmware improves many 3D printers, but does take some work to install.

The Raspberry Pi 4 software environment served as the foundation for the Raspberry Pi 5, with numerous features being added and refined throughout the Pi 4’s lifecycle.

The email includes a message that 'The new firmware for Raspberry Pi 4 contains improvements to optimize heat generation,' along with a test version of the pre-release firmware, afrank said.

The Raspberry Pi Foundation has put a lot of work into their software stack. You need only look at a few of the Allwinnner-based Pi clones for the best evidence of this, but the Pi Foundation&#8217… ...

It has been pretty quiet on the Raspberry Pi operating system since the rash of updates around Christmas/New Year. Not that there hasn't been plenty of other interesting things going on, of course ...

Hands-On with the Raspberry Pi Zero, part 3: Software With the hardware basics out of the way, it's time to take a look at the software: Raspbian Linux.

The firmware is simple and in C so it can support many microprocessors including common 8-bit and 32-bit CPUs found in 3D printers. Klipper is able to achieve precise high stepping rates.
