The next big release of the distribution Ubuntu Linux it will be Ubuntu 21.04 according to Canonical which published the official release schedule. In the program there is also the date of final issue.
After the release of Ubuntu 20.10 (Groovy Gorilla), Ubuntu 21.04 will be released, whose code name will start with the word "Hirsute" and will be followed by an animal name starting with H, which will probably be voted on soon by community.
If you want to give Ubuntu developers some suggestions on the animal or take a look see the post at Ubuntu Discourse.
Until the next code name is decided, development on Ubuntu 21.04 will begin on October 29 with the upgrade of the toolbox based on the current version of Ubuntu 20.10.
As the issue number indicates, the final version is expected in April (fourth month) of 2021. And according to the official release schedule the final date is set for April 22, 2021.
It's too early to know the new features of Ubuntu 21.04 but one thing is for sure, it will be released with the upcoming GNOME 40 desktop environment and if I'm not mistaken it will use Linux kernel 5.11 which will "play" that space.
Ubuntu 21.04 will only be supported for 9 months while the next LTS (Long Term Support) release will be Ubuntu 22.04 LTS to be released in April 2022.
