More Frequent Python Releases?
“Łukasz Langa, who is the release manager for the upcoming 3.8 release, as well as the manager for the date-to-be-determined release of 3.9, has proposed PEP 596 (“Python 3.9 Release Schedule (doubling the release cadence)”). As its name would imply, the PEP proposes halving the current release cycle to nine months, which would make the 3.9 release happen in June 2020.”
