Hi It seems to me that http://schema.koha-community.org/ is not up to date (it shows the date of Mon Jan 11 08:19 NZDT 2016). For example Koha 16.11 has 70 fields in table "borrowers" but SchemaSpy still only shows 67 of them (like in Koha 16.05), missing the new fields "checkprevcheckout", "updated_on" and "lastseen". * http://schema.koha-community.org/tables/borrowers.html Would someone with the needed privileges please update this database description? Also in Koha menu "Tools > Import patrons" the help text "Field list" does miss some fields: the three mentioned above and also "privacy_guarantor_checkouts" (introduced in Koha 16.05 I guess). This leads me to another question: Is there any database description of older Koha versions (e. g. Koha 3.20, Koha 3.18) or will the database analysis by SchemaSpy always just overwrite and thus destroy all older status?
