To make it more clear rather than an edit to the above:
Deprecate pam_cracklib, there are two better alternatives to this
obsolete module: pam_passwdqc from passwdqc project and pam_pwquality
Deprecate pam_tally and pam_tally2 in favour of pam_faillock.
Those are the 2 things that happened ^ thats this ‘issue’.
Even without pacnews … thats all you need to know really.
( though some extra jazz from the new files probably isnt wrong like me adding user_readenv=1 … as seen here: [Unstable Update] 2020-08-22 - Pamac, Mate 1.24.1, GCC 10.2, Python, Haskell )
AGAIN - it is important to note that this is all system dependent.
