Firmware For A20M(GT2560 V4.1B Support 3Dtouch) V2.3 ( 2020-11-11 )

[cryoglobe]

Hello guys

I just see ( in the download list of my A20M ) that there is new firmware that support 3dtouch
I currently have the 1.1.8_02 ..
I wanted to upgrade to the 2.2 ... but will go for this 2.3

Question 1 :
Where can I find the releases notes between those 3 versions ?

Question 2 :
When I did the setup of the 1.1.8_02 in the same time than my 3dtouch ... I encountered a really high under-extrusion issue
I had to increase my extruders esteps to 931.6 ...
-- for information my printer is only 2 weeks old , there is no clog ... I checked yesterday with a small cleanup. --

==> Am I the only one with that ... or anybody else also had to put such a high number ?
