Ubuntu 19.10 lifecycle will end in July this year, the largest version within a period of time is Ubuntu 20.04 LTS, its major updates and improvements will terminate in 2030. Ubuntu 20.04 is the first eight LTS version, scheduled for release on April 23 this year.
Two days ago we reported 20.04 LTS version of Ubuntu update schedule , describes the release time of each node of the situation, take a look at 20.04 today will bring any bright spots.
The first is the theme of change , Yaru there will be a change from light to dark theme optional, check boxes, radio buttons, and sliders and a progress bar under the theme, no longer blue or green, and purple replace it. Switch from green to purple, the overall reduction in the confused color, while not destroy the harmony Ubuntu itself.
Secondly, another long-awaited Ubuntu community needs will also be met, the system will delete the Amazon application pre-installed . Amazon icon on the Ubuntu desktop has been hung, which has long been Tucao people, because it is relatively tasteless, related survey data also reflects this. The changes, especially for the preferred generally are not used to shopping in Chinese Amazon people, is a good thing.
Ubuntu 20.04 will use the Linux 5.4 kernel, this version has a kernel lock mode and exFAT support new features and so on.
Kernel Lock feature is designed to prevent tampering with the root account kernel code to draw a line between the user mode process and code. With this feature enabled, even if the root account can not access some kernel functions to protect the operating system from damage to the root account.
exFAT 文件系统则是 FAT32 的替代者，它由微软开发，但是不仅用于 Windows 系统，目前 exFAT 在整个电子行业中都得到了广泛应用，特别是 SD 卡、USB 闪存驱动、数码相机和 MP3 播放器中使用最为充分，你平时用这些电子产品的时候，多半就使用到了 exFAT 技术。
另一方面，在 19.10 版本中引入的 ZFS 作为根目录的支持会进一步得到改进，但是，它将保持实验状态。
关于 ZFS 的争论近期也因为 Linus Torvalds 的参与而白热化，他在某个论坛上讨论关于内核的相关问题时，提到了 ZFS 并表明了自己的态度，在 Oracle 对 ZFS 的代码进行重新授权以使其能更友好地被引入到 Linux 内核主线之前，他不会推荐使用 ZFS，同时，即便抛开许可证的原因，Linus 也觉得 ZFS 的综合性能并不特别强。随后有人公开宣称 Linus 不懂 ZFS。
此外，20.04 其它增强功能包括：
- GNOME 从 v3.34 升级到 v3.36
- 游戏相关的改进
正式版将在 4 月 23 发布，拭目以待。
