I am unsure, when to update the mycropython on my board:
Usually I tend more to the unstable/"bleeding edge" kind of software (in general) then to the other end, where
is as stable as old (exaggerating a lot here..

I have a clone of the mycropython repo (github) on my harddisk. Last change according to the log
is: "Date: Thu Oct 29 17:36:04 2020 +1100 by Damien".
If I take a look to the daily builds (for the generic ESP32, WROVER-B) I find:
GENERIC-SPIRAM : esp32spiram-idf4-20201103-unstable-v1.13-148-ged7ddd4dd.bin
GENERIC-SPIRAM : esp32spiram-idf4-20201029-unstable-v1.13-143-g25c4563f2.bin
GENERIC-SPIRAM : esp32spiram-idf4-20201029-unstable-v1.13-127-g368c1a096.bin
GENERIC-SPIRAM : esp32spiram-idf4-20201028-unstable-v1.13-126-g05f95682e.bin
of the last four days (this is the firmware version I am currently using). All builds have a different
hash...therefore there is some change....or isn't (according to the log)?
I obviously miss something...?

A "git pull" says "...is up to date"...
If something was change...where can I find, what it was?
Cheers,
mcc
