Hi Dirk, your recent upload of tiledb 2.15.0-1 into unstable is quite unfortunate in freeze policy. You should have waited at least until 2.14.1-2 fixing this bug to migrate to testing. You would need to ask release team for migration of 2.15.0 which will probably be refused even if you would be able to fix the regression in autopkgtest[1].
My recommendation would be to upload a version 2.15.0-2+really_2.14.1 if you want to avoid to use an epoch. It would be great if you could stop uploading any new versions to unstable and rather choose experimental since currently only small targeted fixes are permitted[2]. Kind regards Andreas.
