Ubuntu Focal user? Expect a Jammy upgrade popup soon
Ubuntu 20.04 is nowhere near end of life, but 22.04 is starting to hit its stride.
As is fairly well understood now, the first release of Ubuntu in each even-numbered year is a Long Term Support (LTS) release. Ubuntu 20.04 "Focal Fossa" gets support and updates until 2025 and won't reach its official end-of-life until 2030. "Jammy Jellyfish" - the 22.04 release - is the replacement LTS version, receiving mainstream support until April 2027 and arriving at its end of life in April 2032.
However, users of the previous LTS release don't start to receive upgrade notifications until the subsequent LTS gets its first point release. For Jammy, if all goes well, that should be today: August 11 is the planned release date for Ubuntu 22.04.1. Canonical has published a list of bug-fixes on its Discourse, and you can also track its status on Launchpad.
Among many others, 22.04.1 contains a fix for the latest speculative-executation flaw, Retbleed. This has led to speculation about a new law of computer speed changes.
