I've updated the change-log, I hope it looks ok ? :)

[pawanpraka1]

let us just keep it : adds a filter for grpc logs to reduce the pollution

[vaniisgh]

got it, this seemed to verbose anyway :), I'm sorry I missed adding the newline again though, realized too late.

[pawanpraka1]

@vaniisgh would you like to work on #135 also?

[vaniisgh]

yes, :) but ... It might take me a few days to get to it if that's ok?

[pawanpraka1]

Thanks @vaniisgh . No problem, whenever you get time.
