(Meant to post this yesterday but crashed hard from lack of sleep)
As of about 17:47:04 UTC on April 23, 2020, Ubuntu Focal Fossa 20.04 LTS has been officially released. The corresponding release announcement email that went out to the
ubuntu-announce mailing list is here.
Therefore, effective as of this post, new 20.04 questions are now to be considered on topic here so long as they comply with the other requirements for on topic posts as defined in the Help Center and here on Meta.
This does not mean that 'older' 20.04 questions can be reopened without discussion or community consensus. Questions which were closed because 20.04 at the time was off topic or questions which are related to upgrading or using 20.04 prior to its official release remain offtopic, unless the community at-large believes (on a case-by-case basis) specific posts should be reopened.
CLOSE REVIEWERS: Do not close new 20.04 questions as "offtopic", effective as of the time of this post, unless they are offtopic for some reason other than the question being about 20.04
