Our sample consists of 4408 objects accounting for 97 per cent of the combined list of OGLE\\,IV and {\\it Gaia}\\,DR2 DCEPs. We determined a variety of period-luminosity ($PL$) and period-Wesenheit $PW$ relationships for Fundamental (F) and First Overtone (1O) pulsators. We discovered for the first time a break in these relationships for 1O DCEPs at $P$=0.58 d.
