• bugfix and proper handling of dummy parts https://gitlab.cern.ch/anstein/hgtd-tools/-/issues/57 (SN reservation tool -> pass username during upload, also introduce dummy parts with SN starting with 99)
• bugfix https://gitlab.cern.ch/anstein/hgtd-tools/-/issues/59 (hover effect for previously disabled buttons is restored, less confusing button behavior for users)
• will tag a new version including those fixes soon (1.8.1) and announce
• two MRs in work: FT measurement upload / preparation script (Frederic), new SN-invalid-category for reports (Martin)
