  The ASTRID2 synchrotron light source has now been in user operation for more than 3 years, and most of the initially unresolved minor issues have been dealt with. This paper will report on the solutions, and give an over-view of the current status. The problem of the fast injection bumpers, which overheated at high currents, has been solved. The 3rd harmonic Landau cavity has been installed, and it has resulted in a much better lifetime and a more stable beam. We observe vertically unstable beams above a given threshold beam current. Initially this threshold was quite low, but with time, as the vacuum chambers have been conditioned more and more, the threshold has increased steadily, and is now close to the design current of 200 mA. It is planned to add 3 more power supplies to each of the pole-face windings, which are found in all 12 dipoles. These three supplies will in addition to the original quadrupole correctors give a vertical corrector, a horizontal corrector and a skew quadrupole corrector. Furthermore we are presently producing a new timing system, which will allow us to run single-bunch operation, and a fast orbit feedback system.
