As part of my Wireshark 2.0 series I keep running into functions or features that have changed. I keep mentioning that you should expect an adjustment period or learning curve.
I use the Statistics -> Endpoints report all the time to determine who is the top talker, listener, or leverage the right-click filtering feature.
In this video I review what is different and encourage you to check it out.
Feel free to suggest any features or functions that you would like me to review.
