Linux Mint 是 [最受欢迎的 Linux 发行版之一](https://itsfoss.com/best-linux-distributions/)。它使用 Ubuntu 作为其基础，特别是它基于 [长期支持](https://itsfoss.com/long-term-support-lts/) 的 Ubuntu 版本，以获得长达 5 年的软件支持。


现在，我们有一个新的版本升级，即 **Linux Mint 21 “Vanessa”**，它基于 4 月份最新发布的 [Ubuntu 22.04 LTS 版本](https://news.itsfoss.com/ubuntu-22-04-release/)。因此，用户可以预期它的安全更新可以支持到 2027 年。


让我们来看看这个版本的亮点。


### Linux Mint 21 Vanessa 的新亮点

它采用了稳定的、改进的 [Linux 5.15 LTS 内核](https://news.itsfoss.com/linux-kernel-5-15-release/)，Linux Mint 21 带来了一系列新的增加、变化和完善。


#### 现有用户的升级工具

现有的 Mint 20.3 用户可以使用新的基于 GUI 的升级工具轻松更新他们的系统。


用户会看到一个需要安装或升级的新软件包的列表，这也包括了对你可能手动添加的第三方 PPA 库的检查。


#### 新的蓝牙管理器

Blueman 现在取代了图形界面的 GNOME 蓝牙管理器 Blueberry。


之所以这样做，主要是因为 Blueman 提供了更多的功能和连接选项，以及对多种桌面环境的更好支持。此外，Blueman 的用户界面与 Linux Mint 完美地融合在一起。


Blueman 包括一些高级选项，可能大多数用户用不到，但它是一个好工具。


#### 新的进程监控托盘图标

不管是对于资深用户还是初级用户来说，一个非常有用的功能是引入了一个新的托盘图标，可以监控进程！


这个托盘图标将通知用户是否有任何自动化进程（如更新和系统快照）在后台运行。


当系统变得缓慢时，Mint 用户将很容易知道该去哪里找到问题！


#### 增强的缩略图支持


![](/data/attachment/album/202208/01/170847zrvg0470xgvjumz6.png)


以前，一些文件类型没有任何缩略图显示，这样的用户体验不是很好。


为了解决这个问题，这个版本引入了一个新的项目 *xapp-thumbnails*，并为包括 AppImage、ePub、MP3、RAW 图片和 WebP 在内的文件类型带来了缩略图支持。


#### XApp 的改进


以前的 Timeshift 备份工具现在成为了一个 XApp，并由 Mint 团队正式维护。此外，在 rsync 模式下，如果快照导致磁盘上的可用空间少于 1GB，则会计算出下一次快照所需的空间并跳过下一次快照。


Xviewer、Warpinator、Thingy 和 WebApp 管理器也有了其他改进。


#### Cinnamon 5.4.2


Linux Mint 的旗舰桌面环境 Cinnamon 得到了良好的内部升级。


默认的窗口管理器 Muffin 现在重新基于较新的 Mutter 3.36 代码库开发。


窗口 UI 也有一些细微的改进，包括主题和动画。

其他一些变化包括：


* 改进了对 AppImage 的支持，这与 Ubuntu 22.04 不同
* 目录中出现了一组新的漂亮的壁纸

Linux Mint is [one of the most popular Linux distros](https://itsfoss.com/best-linux-distributions/?ref=news.itsfoss.com) out there. Moreover, it uses Ubuntu as its base and particularly the [Long Term Support](https://itsfoss.com/long-term-support-lts/?ref=news.itsfoss.com) releases for up to 5 years of software support.

Now, we have a new version upgrade, i.e. **Linux Mint 21 “Vanessa”** based on the latest [Ubuntu 22.04 LTS release](https://news.itsfoss.com/ubuntu-22-04-release/), which was released in April. Thus, users can expect security updates until 2027.

Let’s take a look at the highlights of this release.

## Linux Mint 21 Vanessa: What’s New?

Along with the stable and improved [Linux 5.15 LTS kernel](https://news.itsfoss.com/linux-kernel-5-15-release/), Linux Mint 21 brings in a host of new additions, changes, and refinements.

### Upgrade Tool for Existing Users

Existing Mint 20.3 users can easily update their system using the new GUI-based upgrade tool.

Users will be shown a list of new packages to be installed/upgraded. This also includes a check for third-party PPA repositories which you may have added manually.

### New Bluetooth Manager

Blueman will now replace the GUI for GNOME Bluetooth manager i.e Blueberry.

The switch was done basically because Blueman simply offered more features, connectivity options, and better support for multiple desktop environments. Moreover, Blueman’s UI blends in perfectly well with Linux Mint.

Blueman includes some advanced options that may be irrelevant to most users, but it is a good tool.

### New Process Monitor Tray icon

![linux mint](https://news.itsfoss.com/content/images/wordpress/2022/07/monitor.png)

A very useful feature for both power and basic users is the introduction of a new tray icon that monitors processes!

The tray icon will notify users if any automated processes like updates and system snapshots are running in the background.

Mint users will easily know where to look whenever their system gets slow!

### Enhanced Thumbnail Support

Previously, some file types did not have any thumbnails displayed. This wasn’t great for the user experience.

To address it, this release introduces a new project *xapp-thumbnails*, and brings thumbnail support for file types that include AppImage, ePub, MP3, RAW pictures, and WebP.

### XApp Improvements

The ever-present Timeshift, the backup utility, is now a XApp and is officially maintained by the Mint team. In addition, the required space for the next snapshot is calculated and skipped if the snapshot leads to less than 1GB of free space on the disk in rsync mode.

Other improvements were also made to Xviewer, Warpinator, Thingy, and WebApp manager.

### Cinnamon 5.4.2

Linux Mint’s flagship desktop environment—Cinnamon—has received good under-the-hood upgrades.

The default windows manager, Muffin, is now re-based on the newer Mutter 3.36 codebase.

There were also subtle improvements to the window UI, including theming and animations.

## Other Feature Additions and Improvements

Some other changes include:

- Improved support for AppImage, unlike Ubuntu 22.04
- A new set of beautiful wallpapers in the catalog.

You can explore more about its new highlights in our dedicated [Linux Mint 21 features](https://itsfoss.com/linux-mint-21-features/?ref=news.itsfoss.com) article.

## Getting Linux Mint 21

If you are using Mint 20.3, you should be able to upgrade to Mint 21 in a few days. A graphical update process should be revealed in a few days.

You can opt for a fresh installation of Linux Mint by grabbing the ISO from its download page.

You can also [get torrent links](https://linuxmint.com/torrents/?ref=news.itsfoss.com) if you have slow or inconsistent internet.

Enjoy fresh Mint 🙂
