https://master.pureos.net/synchrotron/ e.g. says
|Affected Package||Direction||Version in Target||Version in Source||Issue|
|choose-mirror||testing -> landing||2.99+deb10u3||2.88pureos1||Requires manual merge of downstream changes with source. `|
To me this looks swapped since version 2.99+deb10u3 is in the *source* suite (where the package is coming from) and 2.88pureos1 is in the target suite (where the package is going to) but the column headings at https://master.pureos.net/synchrotron/ say the opposite.
