Ubuntu 20.10, codenamed Groovy Gorilla, was released on 22 October 2020. This release is based on the Linux kernel 5.8 which introduces support for several modern hardware devices and protocols. Notable features include support for USB4, AMD Zen 3 CPUs and Intel Ice Lake and Tiger Lake graphics as well as initial support for booting Power10 processors. GNOME 3.38 brings enhancements to the core GNOME apps and tweaked the app grid, among other user experience improvements. Ubuntu 20.10 is the first release to feature desktop images for the Raspberry Pi 4 (4GB and 8GB models) and the Compute Module 4. Older Pi models with less memory may still be able to boot but they are not officially supported.
An updated toolchain set includes glibc 2.32, OpenJDK 11, rustc 1.41, GCC 10, LLVM 11, Python 3.8.6, ruby 2.7.0, php 7.4.9, perl 5.30 and golang 1.13. In addition to these, nftables is now the default firewall backend, replacing iptables.
In an October 2020 review in HowToGeek, Dave McKay concluded, "we recommend that most people stick with Ubuntu 20.04 LTS for stability. Ubuntu 20.10 doesn’t offer any huge improvements. Rather, it just shows that Ubuntu is still a solid platform, making good progress toward its next LTS release in 2022 ... Canonical estimates that 95% of Ubuntu installations are LTS versions. If that’s true, then plainly interim builds won’t appeal to many people who use Ubuntu. Even if Canonical’s figures are slightly off, it’s obvious the vast majority prefer stability and guaranteed long-term support over the incremental benefits of interim builds."
Tim Anderson of The Register concluded, "...this is not the biggest of Ubuntu releases but keeps the momentum going for Canonical's distribution, hugely popular for server use on public cloud and becoming more polished for desktop users too."
Bogdan Popa, writing for Softpedia, noted of this release, "Ubuntu was, is, and will probably remain the leading Linux distribution out there, at least as far as the number of users is considered."
A review in Full Circle magazine concluded:
While Ubuntu 20.10 is a really solid release, it has surprisingly few new features for a release that initiates a new Ubuntu development cycle. In many ways this is probably a good sign, though. After 33 releases over 16 years, Ubuntu [is] a very mature Linux distribution and it gets almost everything right. There is not really a lot that needs changing, beyond updating the hardware support for the next generation of computers and also updating the default applications, both of which this release does. These days most Ubuntu users run the current LTS release and only upgrade when a new LTS version comes out. This standard release offers very little to entice most Ubuntu users to switch, especially since it has only nine months of support.
