CII v13 is planned for 2022Q2 (based on the list from november 2021).
PVElite 24 was planned for 2021Q4 and is just released.
Based on that scheme we can expect CII v13 at the end of 2022Q2/beginning of 2022Q3 (june/july 2022).

B31.3-2020 was issued June 18, 2021, becoming effective 6 months later. Updates will be incorporated in CII approx 1 year after release of the code.

What happened to the "software is always up-to-date with the latest code" approach?

(not trying to be harsh, but I see competitors pushing the market with the "we are up-to-date and CII is not" argument. And I know there is the willingness, especially with from the old Coade crew, to keep the software up-to-date).
