Ubuntu 20.10 released is codenamed "Groovy Gorilla". This brings yet another version of a remarkable operating system in the Ubuntu ecosystem, with the latest and some of the greatest open source technologies in a high-quality, easy-to-use Linux distribution.

Note that Ubuntu 20.04 is a long-term support (LTS) release, which will be supported for 5 years. Ubuntu 20.10 is a non-LTS release, which means it will be supported for 9 months only, until July 2021. If you prefer stability over bleeding edge, then stick with Ubuntu 20.04.
