After some days off, I returned to my work on GHC. I looked up my tickets in Gitlab with a search on assignee=RolandSenn [1]. The system returned a list of 8 open tickets. Two of them are interesting: #14025 and #15336. Once upon a time I assigned them to me, worked on them, but unfortunately then I found them too difficult. So a couple of weeks ago I unassigned them in the good old Trac system. It seems, that these unassign operations weren't copied to Gitlab! For my 2 tickets, this is no problem, I can re-unassign them manually. However, I think, there are other tickets that were unassinged by their previous owners some time ago. Most probably some or all of them now got re-assinged during the migration to Gitlab.
