There is a "red-lined" version of the public draft distributed on July 19, 2017 (here), showing changes from the previous public draft distributed on February 21, 2017.
However, there is not a red-lined version that shows changes between the revision and the current APP. Although many policies and procedures are not changed from the current APP, the revised APP was reorganized into a logical sequence with each area (such as tenure) described in one place. Throughout the revised APP, descriptions of policies and procedures have been revised to improve clarity. Because the entire document has been reorganized and rewritten, a ‘red-lined’ version would be entirely red-lined and impossible to read.
