The dataentries will be updated to 19.07 over the weekend.
I think so too.
When the instructions are updated, they should refer as much as possible to "the images shown in the table above", i.e. the datatable showing the download links. This way the instructions will always be up to date, without the need to adjust the download link with each new release.
Should there be the rare case that a specific older version is required, it should be mentioned explicitly and with emphasis (like "Note: 17.01.5 image required, more recent releases will not work / lead to bootloop / config changes can not be saved / other reasons for not working.")
