M900 update 740B104 and peer-to-peer

Hello
version 740B104 states "Known Bug: Peer to Peer mode cannot be used reliably in the version. Use Multicast or LAN Sync (Multicast) instead!"
but the release not indicates:
"Peer to Peer mode working in all LAN Sync scenarios"
What is the right information?
