2.09.35 : near the end of 2021 (so close to the 2.10 release date)
2.09.55 : in July 2022 (the official release of the new math engine)
2.10.00 : a few days before the ctx 2022 meeting (starting September 19)
- 2.10.01 : mid October 2022
+ 2.10.01 : mid October 2022 (some more upgrades of the math engine)
+ 2.10.05 : late January 2023
At some point the \CONTEXT\ group will be responsible for guaranteeing that the official version
is what comes with \CONTEXT\ and that long term support and stabilty is guaranteed and that no
feature creep or messing up happens. We'll see.
