Releases page - different downloads



On the releases page (, I notice there is two downloads for each platform, one with symbols in the filename and one without - what is the difference between the two?

I also notice that with the latest release there is an additional download, chromedriver… What is this for and how do we include it in the bundle?

Thanks in advance,


Symbols generally refers to extra debugging information for native code to translate memory locations back into variable and function names under a debugger, i.e. the “symbol” that the memory location represents.

I don’t know what the chromedriver package is for.
