Upgraded from 4.8 to 4.9 printer now prints @ 110 to 120% size

I sliced several files the past few day's on 4.8 Cura, and ended up with accurate prints. Today I sliced in the 4.9 update - dimensions in Cura were correct per model size so the model I drafted in Fusion was not inaccurate - Yet when I generate the gcode and print the model comes out being 10 to 20% larger then the original. Deleted and reloaded my 3rd party printer settings deleting original configuration setting to try that but same problem. Never experienced this issue before?  

 

JG Aurora A5 (original)

my print size is OK. use the JG Aurora A5 community firmware. But the Brim width is set to 150% (thin like a needle). and all flowrates to 140% to get a proper result. and please tell the community that the initial layer height must be, leveling distance + initial layer height = layerheight. its simply wrong that increasing this value increases adhäsion to the bed. when u choose initial layer height of  i.e. 0.25  your true value is 0.25 +0.2 leveling distance. if u increase that 0.4 u`ll get only maggots on the bed.the extruder is hovering 0.6mm over the bed. better reduce to 0.1 for better adhäsion.
