  The Eu­ro­pean Syn­chrotron Ra­di­a­tion Fa­cil­i­ty (ESRF) is now fully en­gaged in a large Up­grade Pro­gramme of its in­fras­truc­ture, beam­lines and X ray source. In this con­text, a first set of 10 in­ser­tion de­vice straight sec­tions are being length­ened from five to six me­tres; a num­ber of them will be op­er­at­ed with cant­ed un­du­la­tors. The in­ser­tion de­vices are them­selves sub­ject to an am­bi­tious de­vel­op­ment pro­gramme to ful­fil the sci­en­tif­ic re­quire­ments. The Radio Fre­quen­cy sys­tem up­grade has start­ed with the re­place­ment of the boost­er klystron-based trans­mit­ter by high power solid state am­pli­fiers, and the de­vel­op­ment of HOM damped cav­i­ties op­er­at­ing at room tem­per­a­ture. A com­plete­ly new DC-AC orbit sta­bi­liza­tion sys­tem using 224 BPMs and 96 orbit steer­ers is cur­rent­ly being com­mis­sioned. The up­grade is con­duct­ed while keep­ing, and even im­prov­ing, rou­tine per­for­mance for the user ser­vice. In par­tic­u­lar the re­cent in­stal­la­tion of new skew quadrupole power sup­plies al­lows rou­tine op­er­a­tion with ultra low ver­ti­cal emit­tance. This paper re­ports on the pre­sent op­er­a­tion per­for­mance of the source, high­light­ing re­cent de­vel­op­ments and those still to come.
