AB  - FLASH, the XUV and soft X-ray free-electron laser user facility at DESY,  is in the transitional period between two substantial upgrade shutdowns  within the FLASH2020+ upgrade project.  FLASH consists of a common part FLASH0 (injector </td><td width="150">
AB  -  superconducting linac),  two FEL beamlines (FLASH1/2) and an experimental beamline FLASH3,  accommodating the plasma wakefield experiment FLASHForward.  The first (2021/22) shutdown was aimed at upgrading FLASH0 and install  an APPLE-III undulator in the otherwise unchainged beamline FLASH2, enhancing  the third harmonic at flexible output polarization. The next (2024/25) shutdown will focus on the complete exchange of the FLASH1  beamline to allow for externally seeded operation in the range from  60 nm down to 4 nm at 1 MHz repetition rate (600 us trains at 10 Hz).  We report on the operation between the two shutdowns which was, to a large  extend, dedicated to FEL operation for users and on the commissioning of the  new features implemented in the last shutdown.
