See [[:commons:Commons:Village pump#MW1.19 - editing old revision and "show changes" does not work]] for maybe more comments by other users. Test: [//commons.wikimedia.org/w/index.php?title=File:P1000372_dsdssdd_ds.JPG&action=edit&oldid=61901086 edit], click compare button below the edit window. Expected: for example the first two "wrong licensing" lines should appear as deleted in the diff. Editing works - but the comparision apparently compares not with the current version (like before 1.19) but with the version you had edited. That is not useful since what will be overwritten when the save is done is the current version.
Perma link, to the discussion: http://commons.wikimedia.org/w/index.php?title=Commons:Village_pump&oldid=67735979#MW1.19_-_editing_old_revision_and_.22show_changes.22_does_not_work
Confirmed. Step to reproduce: create a new page with text: "this is first revision". Save page. Edit page and append text "this is second revision". Save page. Browse to history, select the oldest revision. The loaded page show "this is first revision". Edit page and append "this is third revision". Press [Show change] The diff loaded is: This is the very first revision. + This is third revision It does not show the removal of the second revision text.
