Ubuntu 23.10：全新版本来袭！
======
![][0]
> Ubuntu 23.10 “Mantic Minotaur” 再度亮相，搭载了 GNOME 45，以及众多引人瞩目的升级。
又一次，一如既往的一年一度，我们迎来全新的 Ubuntu 发布！
这次发布的版本是 **Ubuntu 23.10** ，这不是一个 [长期支持][1]（LTS）版本，它的代号是 “Mantic Minotaur” （预言牛头人）。
非 LTS 版本更偏向于满足那些想要获取到 Ubuntu 最新以及最出众特性的用户。
对于那些希望长时间坚守一个版本的用户，我们建议使用 LTS 版本，比如 [Ubuntu 20.04][2] 和 [Ubuntu 22.04][3]。
总之，让我们深入了解这次发布的新版本，去发现其中的亮点。
> 💡 Ubuntu 23.10 将会 **提供九个月的支持**，一直到 2024 年 7 月为止。
### ⭐ Ubuntu 23.10：新版调整了什么？
![][4]
即使这是一个非 LTS 发布，但是 **Ubuntu 23.10 却包含了许多有趣的新特性和升级**。
一些主要亮点包括：
* 更新升级的安装程序
* 受限的非特权用户命名空间
* GNOME 45
* 全新的壁纸
* 基于 Flutter 的应用商店
* Linux 内核 6.5
### 更新升级的安装程序
![][5]
首先，Ubuntu 23.10 的安装程序 **开始实验性地支持两大重要功能** ：
其一是 [TPM 支持的全盘加密（FDE）][6]，这意味着采用全新的加密机制。它将与你主板上的 TPM 芯片协同运作。
其二是期待已久的 [ZFS 支持][7] 再次回归到安装程序中，它在 [Ubuntu 23.04][8] 被移除。
> 📋 更广泛的 TPM 支持的全盘加密硬件支持将在 Ubuntu 24.04 LTS 中推出。
### 受限的非特权用户命名空间
![][9]
Ubuntu 23.10 首次推出一项新的安全功能。它限制了内核的 “非特权用户命名空间” 特性，这有助于应用程序创建更安全的沙箱环境。
这个特性很有用，那为什么要限制它呢? 原因在于，这个内核特性可能被攻击者利用。
为了消除与这个特性相关的风险，[AppArmor][10] 将被用于有选择地允许/禁止非特权用户命名空间。
这个安全特性默认是关闭的，但可以通过命令行选择开启。Canonical 将搜集用户反馈，然后可能决定通过更新将其设为默认。
### GNOME 45
![][11]
Ubuntu 23.10 提供了最新发布的 [GNOME 45][12] 桌面环境，它包括了 **优化过的系统设置应用**、**更新的核心应用**，并 **新增了两个应用**，名为 <ruby>[放大镜][13]<rt>Loupe</rt></ruby> 和 <ruby>[快照][14]<rt>Snapshot</rt></ruby>。
新的 [药丸形工作空间指示器][15] 也在这次发布中首次亮相，虽然不是每个人都会喜欢。
### 新的壁纸
![][17]
Ubuntu 23.10 版本发布，也不忘继续传统，**推出了全新的壁纸** ，这些壁纸主题都与其代号保持一致。所有壁纸看起来都非常不错，这些都是从几个月前举行的 Mantic Minotaur [壁纸比赛][18] 中被选中的。
你可以通过 [官方博客][19] 查找更多有关这些极酷壁纸的信息。
> 📋 我个人特别喜欢 “Bodacious Bovine” 的浅色/深色版本。
### 基于 Flutter 的应用商店
![][20]
得益于在 Ubuntu 23.10 上推出了 **全新的 [基于 Flutter 的商店][21]** ，Canonical 推将 Ubuntu 各种元素 Flutter 化的努力见到了效果。这个新商店拥有 **更新的布局**、**全新的应用视图** ，以及 **更好的搜索功能**。
你在其中可以找到 Snap 和 Deb 包。
### Linux 内核 6.5
![][23]
首先，让我们来了解下让一切变为可能的原动力。Ubuntu 23.10 版本采用了相对更新的 [Linux 内核 6.5][24]。
这一特性让 Ubuntu 能够使用到一些新的硬件支持，如 **Wi-Fi 7**、**USB4**、**针对 AMD FreeSync 视频的即插即用支持**，以及**对 AMD Radeon RX 7000 系列显卡的超频支持** 等。
### 🛠️ 其他变动
除了之前提到的特性，还有一些其他值得注意的变动：
* 支持最新发布的 [树莓派 5][25] 和 [HiFive Pro P550][26]。
* [为 PPA 提供增强的安全性][27]。
* 对 Rust 的支持进一步增强。
* 加入了 [Shotwell 0.32][28]。
* 推出了全新升级的平铺辅助工具。
想要了解更多关于此版本的详细信息，你可以查阅我们之前发布的关于 [Ubuntu 23.10 特性][29] 的报告，或者直接阅读官方的版本发布说明。
## 📥 下载 Ubuntu 23.10
> 📋 请注意，在发布公告后，下载可能还需要一段时间。

Ubuntu 23.10: The Big Release is Here!
======
Ubuntu 23.10 'Mantic Minotaur' is now here with GNOME 45 and other
fantastic improvements.
It is that time of the year again, when we get to see a new Ubuntu release!
This time it's **Ubuntu 23.10** , which is not a [Long-Term support][1] (LTS) version, and is code-named as ' **Mantic Minotaur** '.
Such releases are geared more towards users who want the latest and greatest that Ubuntu has to offer.
For users who want to stick with one version for a long time, we suggest LTS releases such as [Ubuntu 20.04][2] and [Ubuntu 22.04][3].
Anyway, let's dig into this release and check out its highlights.
💡
Ubuntu 23.10 will be **supported for nine months** until July 2024.
## ⭐ Ubuntu 23.10: What's New?
![][4]
Even though this is a non-LTS release, **Ubuntu 23.10 packs in loads of interesting features and improvements**.
Some key highlights include:
* **Installer Upgrades**
* **Restricted unprivileged user namespaces**
* **GNOME 45**
* **New Wallpapers**
* **Flutter-based App Store**
* **Linux Kernel 6.5**
### Installer Upgrades
![][5]
For starters, the installer for Ubuntu 23.10 features **experimental support for two major features** :
One is the **[TPM-backed full-disk encryption][6]** (FDE) **,** that sees a completely revamped mechanism being implemented for encrypting disks. It works in tandem with the TPM chip on your motherboard.
The other is the long-awaited return of [**ZFS support**][7] to the installer, after it was dropped in the [Ubuntu 23.04][8] release.
📋
Broader hardware support for TPM-backed FDE is set to arrive with Ubuntu 24.04 LTS.
### Restricted unprivileged user namespaces
![][9]
Ubuntu 23.10 debuts a new security feature. It restricts the kernel feature ' _unprivileged user namespaces_ ', which is useful to let applications create a more secure sandbox.
If it is useful, why restrict it? Well, the kernel feature lets attackers exploit a system.
So, to eliminate the risk associated with the feature, [AppArmor][10] will be used to selectively allow/disallow unprivileged user namespaces.
This security feature will not be enabled by default but as an opt-in via command line. Canonical will collect user feedback and then may decide to push it as the default with an update.
### GNOME 45
![][11]
Ubuntu 23.10 features the recently released [**GNOME 45**][12] desktop environment that features a **tweaked system settings app** , **updated core apps** with the **inclusion of two new apps** called ' **[Loupe][13]** ' and ' **[Snapshot][14]** '.
Even the new [**pill-shaped workspace indicator**][15] has made a debut with this release, though not everyone might be on board with that.
![][16]
### New Wallpapers
![][17]
As is tradition, the Ubuntu 23.10 release also **features new wallpapers** themed according to its code-name. All of them look quite nice, and these were selected from the Mantic Minotaur [wallpaper competition][18] that was held a few months prior.
You can check the [official blog][19] to know more about these extremely cool wallpapers.
📋
Personally, I love the 'Bodacious Bovine' Light/Dark ones. 😄
### Flutter-based App Store
![][20]
Canonical's push for Flutter-basing the various elements of Ubuntu has received a boost thanks to the implementation of **a new[Flutter-based store][21] on Ubuntu 23.10**. It features **an updated layout** , **a new application view** , and **better search functionality**.
You can find both Snap and Deb packages with it.
![][22]
### Linux Kernel 6.5
![][23]
And finally, we have the magic sauce that makes it all happen. **Ubuntu 23.10 features the relatively new[Linux kernel 6.5][24]**.
This allows Ubuntu to take advantage of the newer support such as **Wi-Fi 7** , **USB4** , **out-of-the-box support for AMD FreeSync video** , **overclocking support for AMD Radeon RX 7000 series graphics cards** and more.
### 🛠️ Other Changes
Other than the highlights, here are some other changes worth noting:
* **Support for the recently released[Raspberry Pi 5][25], and [HiFive Pro P550][26].**
* **[Enhanced security][27] for PPAs**
* **Better support for Rust.**
* **Inclusion of[Shotwell 0.32][28].**
* **Introduction of a vastly improved tiling assistant.**
