“framework-zephyr 2.20400.201210 (2.4.0)”.
Not sure why there is still a reference to “2.2”?

2.20400.201210 does not mean Zephyr v2.2 but major PIO package version 2, inner version 20400 → 2.4.0 in semver, and 2020 December 10th for the date.

Using current ESP-IDF / Arduino-ESP32

Read Releases · platformio/platform-espressif32 · GitHub [grafik] The same is visible from the version number since the format is <major packet version>.<underlying packet version>.<date>, so this means framework-espidf major packet version 3 (PIO-internal numbering), 40100 → 4.1.0 underlying version of ESP-IDF, date code 2020 27th August.
