Version number not in file name when export stl files

Hi,

I have updated Fusion 360 to the latest version today. I have come to export my stl file, I didn’t notice the version number had not been wrote in the file name so when I clicked export it wanted to over write an existing file I had already exported.  

Is this something that has happened in the update?

Can I reverse or change a setting so I automatically generate and STL file with the current version of file I have just saved?

Thanks

Graham
