Ubuntu 21.04 releases: Wayland has been used by default
Recently, Canonical officially released Ubuntu 21.04, which includes native Microsoft Active Directory integration, SDK for Flutter application development, and the default enabling Wayland to replace the 36-year-old X Window System.
Although Ubuntu 21.04 is a stable version, the 21.04 version does not have a long-term support version, so this version will end support in January 2022. If you want long-term support, Ubuntu 20.04 LTS may be a better choice for now, and it will continue to receive support until 2025 as planned.
Ubuntu 21.04 upgrades the Linux kernel to 5.11, which means it supports newer hardware, but Canonical said they need more time to polish GNOME, so in this update, they decided not to introduce the latest GNOME 40 for the time being.
By introducing Active Directory (AD) support, Ubuntu 21.04 adds the ability to configure system settings from the AD domain controller. Using the group policy client, system administrators can specify security policies on all connected clients, such as password policies, user access control, desktop environment settings, login interface, background, and preferred applications.
