There are some errors found in the documentation bundled in the yesterday releases. This by no means indicates any implementation bug.
README: add a description for the "md5" option, which makes pam_mysql use MD5 crypt with the "crypt" option set to "Y".
README (0.7 only): in the description of the "config_file" option, "users.use_md5" directive is wrongly explained that its counterpart is "where" option. That is actually the "md5" option and "users.where_clause" is the correct directive that has "where" as its counterpart.
