This article is translated from the Official Fedora announcement.

Today, I’m excited to share the hard work of thousands of Fedora project contributors: our latest release, Fedora 33, is here! This is a big release with a lot of changes, but I believe all this work will also make you feel comfortable and achieve our goal of bringing you the latest stable, powerful, robust FREE and open source software with many easy-to-use products.

If you don’t want to waste time trying it out, go to getFedora.org/ and download it now. Read on to learn more!

Find the Right Fedora flavor for you!

Fedora Edition is targeted for a variety of “embodied” specific uses in desktop, server, and cloud environments, and now it’s also available for the Internet of Things.

Fedora Workstation focuses on the desktop, especially for software developers who want the “just use it” Linux operating system experience. This release features GNOME 3.38, which, as always, has a lot of great improvements. New Tour apps help new users learn how they operate. As with all our other desktop-oriented variants, Fedora Workstation now uses BTRFS as the default file system. There are many great enhancements that come with these releases, and this advanced file system is the foundation for them. For your visual enjoyment, Fedora 33 Workstation now provides an animated background by default (which changes based on the time of day).

Fedora CoreOS is an emerging version of Fedora. It is an automatically updated, minimal operating system for safely running containerized workloads on a large scale. It provides several update streams that can follow automatic updates roughly every two weeks. The next stream is currently based on Fedora 33, with testing and stable streams to follow. You can find information about the artifacts published with the Next flow from the download page and information on how to use them in the Fedora CoreOS documentation.

Fedora IoT, newly promoted to Edition status, provides a solid foundation for the IoT ecosystem and edge computing use cases. Among many features, Fedora 33 IoT introduced the Platform AbstRaction for SECurity (PARSEC), an open source initiative that provides common apis for hardware SECurity and encryption services in a platform-independent way.

Of course, we don’t just make the “official version”, but also Fedora Spin and Lab. Fedora Spin and Lab target different audiences and use cases, including Fedora CompNeuro, which brings a number of open source computational modeling tools to neuroscience, as well as desktop environments such as KDE Plasma and Xfce.

Also, don’t forget we have backup architectures: ARM AArch64, Power, and S390x. New features available in Fedora 33 enable AArch64 users to develop cross-platform using the.NET Core language. We have improved support for Pine64 devices, NVidia Jetson 64-bit platforms, and Rockchip System-on-Chip (SoC) devices, including Rock960, RockPro64, and Rock64. (An update, though: some of these devices may have boot problems. Upgrading from existing Fedora 32 is no problem. More information will be posted on the common error page.)

We are also pleased to announce that Fedora Cloud Image and Fedora CoreOS will be available for the first time in Amazon’s AWS Marketplace alongside Fedora 33. Fedora Cloud images have existed in The Amazon Cloud for over a decade, and you can launch our official image with an AMI ID ora click down. The market provided another way to get the same thing, significantly expanding Fedora’s popularity. This will also make our cloud images available faster in new AWS regions. Special thanks to David Duncan for making this happen!

Conventional improvement

No matter which version of Fedora you are using, you will get the latest version available from the open source world. Following our First principles, we updated key programming languages and system library packages, including Python 3.9, Ruby on Rails 6.0, and Perl 5.32. In Fedora KDE, we continued the work in Fedora 32 Workstation and enabled the EarlyOOM service by default to improve the user experience in low-memory situations.

To make Fedora’s default experience better, we set Nano as the default editor. Nano is a new user-friendly editor. Of course, those who want a powerful editor like VI can set the default editor themselves.

We’re glad you got to try the new version! Go to getFedora.org/ and download it now. Or if you are already running the Fedora operating system, follow these simple upgrade instructions. For more information about the new Fedora 33 features, see the release notes.

Instructions on safe startup

Secure Boot Secure Boot is a security standard that ensures that only officially signed operating system software can be loaded onto your computer. This is important to prevent persistent malware, which can hide in your computer’s firmware and survive even a re-installation of the operating system. However, after the Boot Hole vulnerability, the encrypted certificate used to sign the Fedora Bootloader Bootloader software is revoked and replaced with a new certificate. Because of the wide-ranging impact, repeal should not be widely implemented until the second quarter of 2021 or later.

However, some users may have received this undo from other operating systems or firmware updates. In this case, Fedora will not be able to install with secure startup enabled. To be clear, this will not affect most users. If it does affect you, you can temporarily disable secure startup. We will release an update signed with the new certificate, available on all supported versions, prior to the widespread certificate revocation, by which time secure startup should be enabled again.

Thank you for your attention

Thanks to the thousands of people who contributed to the Fedora project during this release cycle, especially those who went the extra way to make this release on time during the pandemic. Fedora is a community and it’s great to see how much we support each other.
