Linux 5.5 what to expect?

The Linux 5.5 kernel already hit the testing repo on Arch and shall be available soon to the stable branch.

The new Linux release comes with a series of major improvements, including full Raspberry Pi 4 and Chromebook Wake-On-Voice support.

“Despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now,” Linus Torvalds announced.

Furthermore, the new Linux kernel introduces AMD GPU overclocking, which is one of the most anticipated improvements especially as Linux is pushing harder in the gaming ecosystem, as well as full support for the newly-released and the upcoming Intel chipsets.

There are additional improvements for virtual machines running on Microsoft Hyper-V, as the platform now supports hibernating as well. And of course, the Linux kernel comes with a series of file system changes, including for XFS, exFAT, and ext4.

LTS kernel

Besides the mainstream kernel, the current LTS kernel, which has version number 4.19, will also be upgraded to kernel version 5.4, the recent mainstream kernel.

Most anticipated kernel release

Even though the upcoming kernel 5.5 ships with a lot of improvements and new features, the most anticipated kernel release is 5.6, especially because it’s supposed to bring quite an impressive lineup of changes. One of them is support for USB4 and WireGuard. Both were announced in December and scheduled to be part of Linux kernel 5.6.

Linus Torvalds also announced the opening of the Linux 5.6 merge window, although as he explains, some delays could happen in the coming weeks.

“The timing for this next merge window isn’t optimal for me – I have some travel and other things going on during the same two weeks, but hopefully it won’t be all that noticeable.  But there might be random timezones, odd hours, and random delays because of that,” he explains.
