PR 2.21.0 install - message received during the install related to PR_check2.rpt having been modified

SUGGESTED

During the install of 2.21.0 a message was received that the PR_check2.rpt has been modified.   I did not proceed with the install.  I may have modified the base check form - we use MICR checks and bank information has to be added to the standard form for every company.  I was aware that some data fields related to the bank information have been added to the form during one of the payroll updates but that was PRIOR to 2.21.0  Can anyone tell me the changes in the form with this update 2.21.0?  I need to determine if all the custom forms we have in place need to be modified\updated.  Your input would be appreciated.  Thanks.
