It's not so easy to get the "right" version of the Chromium version used in Maxthon, but you should notice, at first that version above 109.x are no more under WS2012R2 usable (so W7, 8, 8.1, WS2012, WS2012R2) (that's a reason why Maxthon is no such rushed to use later version, don't want to loose a part of it's mainly W7 users)
Another trail to get the real version of chromium used is just to check the reference branch :
And compare it to the less significant build digit of the Chromium versioning :
https://chromium.googlesource.com/chromium/src/+refs
So our Actual Chromium version is still 109.0.5414.146... the 146 cames from 1460 cause padded to four digits.
