Fedora 33 is officially here!
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
Today, I’m excited to share the results of the hard work of thousands of contributors to the Fedora Project: our latest release, Fedora 33, is here! This is a big release with a lot of change, but I believe all that work will also make it a comfortable one, fulfilling our goal of bringing you the latest stable, powerful, and robust free and open source software in many easy to use offerings.
|
||||
|
||||
If you just want to get to the bits without delay, head over to <https://getfedora.org/> right now. For details, read on!
|
||||
|
||||
### **Find the Fedora flavor that’s right for you!**
|
||||
|
||||
Fedora Editions are targeted outputs geared toward specific “showcase” uses on the desktop, in server and cloud environments—and now for Internet of Things as well.
|
||||
|
||||
Fedora Workstation focuses on the desktop, and in particular, it’s geared toward software developers who want a “just works” Linux operating system experience. This release features [GNOME 3.38][2], which has plenty of great improvements as usual. The addition of the Tour application helps new users learn their way around. And like all of our other desktop-oriented variants, Fedora Workstation now uses [BTRFS as the default filesystem][3]. This advanced filesystem lays the foundation for bringing a lot of great enhancements in upcoming releases. For your visual enjoyment, Fedora 33 Workstation now features an animated background (based on time of day) by default.
|
||||
|
||||
Fedora CoreOS is an emerging Fedora Edition. It’s an automatically-updating, minimal operating system for running containerized workloads securely and at scale. It offers several [update streams][4] that can be followed for automatic updates that occur roughly every two weeks. Currently the **next** stream is based on Fedora 33, with the **testing** and **stable** streams to follow. You can find information about released artifacts that follow the **next** stream from [the download page][5] and information about how to use those artifacts in the [Fedora CoreOS Documentation][6].
|
||||
|
||||
[Fedora IoT][7], newly promoted to Edition status, provides a strong foundation for IoT ecosystems and edge computing use cases. Among many other features, Fedora 33 IoT introduces the Platform AbstRaction for SECurity (PARSEC), an open-source initiative to provide a common API to hardware security and cryptographic services in a platform-agnostic way.
|
||||
|
||||
Of course, we produce more than just the Editions. [Fedora Spins][8] and [Labs][9] target a variety of audiences and use cases, including [Fedora CompNeuro][10], which brings a plethora of open source computational modelling tools for neuroscience, and desktop environments like [KDE Plasma][11] and [Xfce][12].
|
||||
|
||||
And, don’t forget our alternate architectures: [ARM AArch64, Power, and S390x][13]. New in Fedora 33, AArch64 users can use the .NET Core language for cross-platform development. We have improved support for Pine64 devices, NVidia Jetson 64 bit platforms, and the Rockchip system-on-a-chip devices including the Rock960, RockPro64, and Rock64. (However, a late-breaking note: there may be problems booting on some of these devices. Upgrading from existing Fedora 32 will be fine. More info will be on the [Common Bugs][14] page as we have it.)
|
||||
|
||||
We’re also excited to announce that the Fedora Cloud Base Image and Fedora CoreOS will be available in Amazon’s [AWS Marketplace][15] for the first time with Fedora 33. Fedora cloud images have been available in the Amazon cloud for over a decade, and you can launch our official images by AMI ID or [with a click][16]. The Marketplace provides an alternate way to get the same thing, with significantly wider visibility for Fedora. This will also make our cloud images available in new AWS regions more quickly. Thank you especially to David Duncan for making this happen!
|
||||
|
||||
### General improvements
|
||||
|
||||
No matter what variant of Fedora you use, you’re getting the latest the open source world has to offer. Following our “[First][17]” foundation, we’ve updated key programming language and system library packages, including Python 3.9, Ruby on Rails 6.0, and Perl 5.32. In Fedora KDE, we’ve followed the work in Fedora 32 Workstation and enabled the EarlyOOM service by default to improve the user experience in low-memory situations.
|
||||
|
||||
To make the default Fedora experience better, we’ve set nano as the default editor. nano is a friendly editor for new users. Those of you who want the power of editors like vi can, of course, set your own default.
|
||||
|
||||
We’re excited for you to try out the new release! Go to <https://getfedora.org/> and download it now. Or if you’re already running a Fedora operating system, follow the easy [upgrade instructions][18]. For more information on the new features in Fedora 33, see the [release notes][19].
|
||||
|
||||
### **A note on Secure Boot**
|
||||
|
||||
Secure Boot is a security standard which ensures that only officially-signed operating system software can load on your computer. This is important for preventing persistent malware which could hide itself in your computer’s firmware and survive even an operating system reinstallation. However, in the wake of the [Boot Hole][20] vulnerability, the cryptographic certificate used to sign Fedora bootloader software will be revoked and replaced with a new one. Because this will have a broad impact, revocation should not happen widely until the second quarter of 2021 or later.
|
||||
|
||||
However, some users may have received this revocation from other operating systems or firmware updates already. In that case, Fedora installations will not boot with Secure Boot enabled. To be clear, this will not affect most users. If it does affect you, you can boot with Secure Boot disabled for the time being. We will release an update signed with the new certificate to be available on all supported releases well before broad-scale certificate revocation takes place, and at that point Secure Boot should be reenabled.
|
||||
|
||||
### **In the unlikely event of a problem….**
|
||||
|
||||
If you run into a problem, check out the [Fedora 33 Common Bugs][14] page, and if you have questions, visit our [Ask Fedora][21] user-support platform.
|
||||
|
||||
### **Thank you everyone**
|
||||
|
||||
Thanks to the thousands of people who contributed to the Fedora Project in this release cycle, and especially to those of you who worked extra hard to make this another on-time release during a pandemic. Fedora is a community, and it’s great to see how much we’ve supported each other.

Fedora 33 正式发布了
|
||||
======
|
||||
|

|
||||
|
||||
今天，我很兴奋地与大家分享数千名 Fedora 项目贡献者辛勤工作的成果：我们的最新版本 Fedora 33 来了! 这是一个有着很多变化的大版本，但我相信所有这些工作也会让您感到舒适，实现我们的目标：即为您带来最新的稳定、强大、健壮的自由和开源软件，并提供许多易于使用的产品。
|
||||
|
||||
如果您不想耽误时间，直接体验，现在就去 <https://getfedora.org/> 下载吧，欲了解详情请继续阅读！
|
||||
|
||||
### 找到适合您的 Fedora 风味！
|
||||
|
||||
Fedora Edition 是针对桌面、服务器和云环境中各种“体现”特定用途的目标产品，现在它也适用于物联网。
|
||||
|
||||
Fedora Workstation 专注于桌面，尤其是面向那些想要“只管去用”的 Linux 操作系统体验的软件开发者。这个版本的特点是 [GNOME 3.38][2]，它一如既往地有很多很棒的改进。新增的 Tour 应用可以帮助新用户学习它们的操作方式。和我们所有其他面向桌面的变体一样，Fedora Workstation 现在使用 [BTRFS 作为默认文件系统][3]。这些发布的版本中带来了很多伟大的增强功能，这个先进的文件系统为之奠定了基础。为了您的视觉享受，Fedora 33 Workstation 现在默认提供了一个动画背景（它会基于一天中的时间变化）。
|
||||
|
||||
Fedora CoreOS 是一个新兴的 Fedora 版本。它是一个自动更新的、最小化的操作系统，用于安全地、大规模地运行容器化工作负载。它提供了几个[更新流][4]，可以遵循大致每两周一次的自动更新。目前 **next** 流是基于 Fedora 33 的，**testing** 和 **stable** 流后继也会跟进。您可以从[下载页面][5]中找到关于跟随 **next** 流发布的工件的信息，并在 [Fedora CoreOS 文档][6]中找到关于如何使用这些工件的信息。
|
||||
|
||||
新晋升为 Edition 状态的 [Fedora IoT][7]，为物联网生态系统和边缘计算用例提供了坚实的基础。在许多功能之外，Fedora 33 IoT 还引入了<ruby>平台抽象安全<rt>Platform AbstRaction for SECurity</rt></ruby>（PARSEC），这是一个开源倡议，以平台无关的方式为硬件安全和加密服务提供了通用 API。
|
||||
|
||||
当然，我们制作的不仅仅是“官方版本”，还有 [Fedora Spin][8]和 [Lab][9]。[Fedora Spin][8] 和 [Lab][9] 针对不同的受众和用例，包括 [Fedora CompNeuro][10]，它为神经科学带来了大量的开源计算建模工具，以及 [KDE Plasma][11] 和 [Xfce][12]等桌面环境。
|
||||
|
||||
此外，别忘了我们还有备用架构：[ARM AArch64、Power 和 S390x][13]。在 Fedora 33 中提供的新功能，AArch64 用户可以使用 .NET Core 语言进行跨平台开发。我们改进了对 Pine64 设备、NVidia Jetson 64 位平台以及 Rockchip 片上系统（SoC）设备的支持，包括 Rock960、RockPro64 和 Rock64。（不过，有个最新的说明：在其中一些设备上可能会出现启动问题。从现有的 Fedora 32 升级是没问题的。更多信息将在[常见错误][14]页面上公布。）
|
||||
|
||||
我们也很高兴地宣布，Fedora 云镜像和 Fedora CoreOS 将首次与 Fedora 33 一起在亚马逊的 [AWS 市场][15] 中提供。Fedora 云镜像在亚马逊云中已经存在了十多年，您可以通过 AMI ID 或[点击一下][16]来启动我们的官方镜像。该市场提供了获得同样东西的另一种方式，显著扩大了 Fedora 的知名度。这也将使我们的云镜像可以更快地在新的 AWS 区域中可用。特别感谢 David Duncan 让这一切成为现实！
|
||||
|
||||
### 常规改进
|
||||
|
||||
无论您使用的是哪种版本的 Fedora，您都会得到开源世界提供的最新版本。遵循我们的 [First][17] 原则，我们更新了关键的编程语言和系统库包，包括 Python 3.9、Ruby on Rails 6.0 和 Perl 5.32。在 Fedora KDE 中，我们沿用了 Fedora 32 Workstation 中的工作，默认启用了 EarlyOOM 服务，以改善低内存情况下的用户体验。
|
||||
|
||||
为了让 Fedora 的默认体验更好，我们将 nano 设置为默认编辑器。nano 是一个对新用户友好的编辑器。当然，那些想要像 vi 这样强大的编辑器的用户可以自己设置默认编辑器。
|
||||
|
||||
我们很高兴您能试用新版本! 前往 <https://getfedora.org/> 并立即下载它。或者如果您已经在运行 Fedora 操作系统，请按照这个简单的[升级说明][18]进行升级。关于 Fedora 33 新特性的更多信息，请参见[发布说明][19]。
|
||||
|
||||
### 关于安全启动的说明
|
||||
|
||||
<ruby>安全启动<rt>Secure Boot</rt></ruby>是一种安全标准，它确保只有官方签署的操作系统软件才能加载到您的计算机上。这对于防止持久恶意软件非常重要，因为这些恶意软件可能会隐藏在您的计算机固件中，甚至在重新安装操作系统时也能存活。然而，在 [Boot Hole][20] 漏洞发生后，用于签署 Fedora <ruby>引导加载器<rt>Bootloader</rt></ruby>软件的加密证书将被撤销，并被新的证书取代。由于这将产生大范围的影响，撤销应该要到 2021 年第二季度或更晚才会广泛推行。
|
||||
|
||||
然而，一些用户可能已经从其他操作系统或固件更新中收到了这种撤销。在这种情况下，Fedora 将不能在启用了安全启动时进行安装。要说明的是，这不会影响大多数用户。如果它确实影响到了您，您可以暂时禁用安全启动。我们会在大范围的证书撤销之前发布一个用新证书签署的更新，在所有支持的版本上都可以使用，到那时，安全启动应该可以重新启用。
|
||||
|
||||
### 万一出现问题时……
|
||||
|
||||
如果您遇到问题，请查看 [Fedora 33 常见错误][14]页面；如果您有疑问，请访问我们的 [Ask Fedora][21] 用户支持平台。
|
||||
|
||||
### 谢谢大家
|
||||
|
||||
感谢在这个发布周期中为 Fedora 项目做出贡献的成千上万的人，尤其是那些在疫情大流行期间为使这个版本准时发布而付出额外努力的人。Fedora 是一个社区，很高兴看到我们如此互相支持。
