  SOLEIL delivers photons to 26 beamlines and 3 new ones are under construction together with the femtoslicing project. Up to 5 filling patterns are available for the users including a low alpha mode; all of them are in Top-up injection. The beam current for the users has been increased to 430 mA in the multibunch mode. The Storage Ring (SR) is running with a new optics incorporating an additional quadrupole triplet in one long straight section. The beam position stability remains excellent. Vertical positions from the dipole X-BPMs have been included in the orbit feedbacks loop with very encouraging results. A feedback loop maintaining the emittance coupling close to 1% for any Insertion Devices (IDs) configuration has been implemented. Up to 25 very diverse IDs are now installed on the SR, and several others are under design or construction. In house developments are being carried out in several domains such as construction of SR dipole power supply spare and of 70 kW-500 MHz solid state amplifiers, design of a pulsed multipole magnet for injection, and a Robinson wiggler, as well as a feasibility study of a local reduction of the emittance in one of the long straight sections.
