It comes with Flutter application development SDK and Microsoft SQL Server for Ubuntu. In addition, this latest Ubuntu release comes with native Active Directory, integrated within it and Wayland graphics. Ubuntu 21.04's Linux kernel ships Wayland with some suitable shots of appearance tweaks, software updates, and performance enhancements. Currently, if you are running using older versions of Ubuntu like Ubuntu 20.04 (Focal Fossa) or Ubuntu 20.10 (Groovy Gorilla) and wish to upgrade to Ubuntu 21.04 directly, this article is for you.
Note that Ubuntu 20.04 is a stable release with long-term support (LTS). This version of Ubuntu will support your system for five years. On the other hand, Ubuntu's new release (21.04) is non-LTS. It will stay in your system for nine months only. Therefore, if you prefer the stable release over new enhancements, do not upgrade your system.
