I used to use
output_directory : "<<temp>>", "copy_output_on_build": true
so I only had the *.tex and *.pdf in my working directory
With 4.5 "copy_output_on_build": true is no longer supported so i had to resort to aux_directory : "<<temp>>". Unfortunately now *.synctex.gz files are bing moved into my workspace folder as well, messing up my nice and clean system.
How do I get rid of that in this new system ?
