Although the basic parameters are set and frozen, improvements in the magnetic lattice and beam optics are still being implemented. In particular, the central dipole in the 5BA cell has been replaced by an all-permanent-magnet dipole with a thin superbend in the center with peak magnetic field of 3.2 T and the operation mode has now symmetry 5, with 15 low βx straight sections and 5 high βx sections. The 3 GeV ring bare lattice emittance is now 0.25 nm.rad.
