We are working on the new model upgrade (IFS cycle 47r2), expected to be the last cycle before ECMWF's computing centre is moving to Bologna. The upgrade includes single-precision for ENS (forecast up to day 46 and hindcast) and HRES (forecast) model. Moreover, the number of ENS model levels will be increased to 137 (currently 91) to bring ENS in line with the vertical resolution of HRES. A summary of the meteorological performance will be made available in November. We have scheduled webinars to introduce the cycle, two in December and one just before the implementation, planned for May 2021.

More details are available at Implementation of IFS Cycle 47r2.
