Beware Chrome Caches Old Custom CSS

phprunner 10.3 - build 34624 x64
This took me several hours to figure out.
I had entered some custom CSS code on the phprunner editor page at the top of the screen.
It didn't work exactly as planned so I went back later to make some changes but they weren't taking affect.
I used INSPECT ELEMENT under the Chrome browser to see the that the custom CSS is reference as: https://myurl/styles/custom/custom.css?34624
phprunner does NOT update the query string "?34624" (the build number) to force the cache to reload the latest CSS version.
So under Google Chrome - you keep getting the old CSS from the cache unless you do a CONTROL-F5 to force the reload to disregard the cache.
I was only able to figure this out using INSPECT ELEMENT in the browser to see the CSS updates weren't coming through.
Hope this helps -
