Thank you for the request. Our Breakpad support is currently limited compared to the features provided by our other SDKs. The ability report the app version to Raygun for each error report generated from a minidump is a feature we would like to support. However we don't have an immediate timeframe set around this feature currently. I will be sure to update this forum once we start to work on allowing application version to be picked up as part of processing minidump files.
