If it was "game crashed, here's the stacktrace" before and now (or later) it's "player put 20 blocks of gold on server IP 127.0.0.1 with players foo, bar, baz present", it's a difference.
This is just speculation on your part? Is that all they were collecting before? And they are not collecting that now. They are collecting:
launcher identifier
user identitifer (XUID)
client session id (changes on restart)
world session id (changes per world load, to be reused for later events)
game version
operating system name and version
Java runtime version
if client or server is modded (same information as on crash logs)
server type (single player, Realms or other)
game mode
