Re: APCC Pro v188.8.131.52 and APCC Standard v184.108.40.206
Any other reason for the upgrade? I am using the version 220.127.116.11 (APCC Pro)I understand completely. You can find the list of the changes in each public build of APCC at this link (you can also find them in APCC's help file):
Also, you can always reinstall an older version of APCC.
