Linus Torvalds released Linux 5.7 with this announcement:
So we had a fairly calm last week, with nothing really screaming “let’s delay one more rc”. Knock wood – let’s hope we don’t have anything silly lurking this time, like the last-minute wifi regression we had in 5.6..
But embarrassing regressions last time notwithstanding, it all looks fine. And most of the discussion I’ve seen the last week or two has been about upcoming features, so the merge window is now open and I’ll start processing pull requests tomorrow as usual. But in the meantime, please give this a whirl.
We’ve got a lot of changes in 5.7 as usual (all the stats look normal – but “normal” for us obviously pretty big and means “almost 14 thousand non-merge commits all over, from close to two thousand developers”), So the appended shortlog is only the small stuff that came in this last week since rc7.

Linux 5.7.1 changes from 5.7
- New, higher-quality exFAT file system from Samsung replacing the exFAT implementation added to Linux 5.4.
- Thermal Pressure in the task scheduler – Thermal Pressure makes the task scheduler more aware of frequency capping, and leads to better task placement among available CPUs in event of overheating, which should lead to better performance numbers. See more details on LWN.
- Tiger Lake enablement – Graphics, thermal & power management, Ethernet
- Coding-style – Deprecate 80-column warning
MIPS Linux 5.7 changes
A few changes came also to MIPS:
- loongson64 irq rework
- dmi support loongson
- replace setup_irq() by request_irq()
- jazz cleanups
- minor cleanups and fixes
Ubuntu 19.10 for latest Raspberry Pi applications
With 19.10 release of Ubuntu Server, Canonical announced official support for the Raspberry Pi 4. The latest board from the Raspberry Pi Foundation sports a faster system-on-a-chip with a processor that uses the Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz). Additionally, it offers up to 4GB of RAM. We are supporting the Raspberry Pi 4 to give developers access to a low-cost board, powerful enough to consolidate compute workloads at the edge.
The Raspberry Pi has established itself as a most accessible platform for innovators in the embedded space. Canonical is dedicated to empowering innovators with open-source software. Consequently, Canonical endeavors to offer full official support for all the boards in the Raspberry Pi family. Canonical will therefore enable both Ubuntu Server and Ubuntu Core for existing and upcoming Pi boards.Ubuntu Roadmap.

Industrial use of Raspberry Pi 4
A year ago, TECHBASE released an updated version of the ModBerry M500 industrial IoT computer, replacing the aging Raspberry Pi 3 with a 3B+, giving it better performance. With the recent launch of the Raspberry Pi 4, TECHBASE has yet again, announced another upgrade to the M500, which now packs the latest single-board computer.
Over 10 million Raspberry Pi’s have been sold and the Raspberry Pi is likely to stay as a new standard in the industry. Official Raspbian OS is free operating system based on Linux Debian optimized for the Raspberry Pi comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation. ModBerry devices are compatible with Raspberry Pi accessories, supported by Raspberry Pi Foundation. ModBerry M500 now with Raspberry Pi 3 Model B+ / Raspberry Pi 4 Model B support.
