# We support the following protocol features:
# SJ3 - extended SJOIN
# NOQUIT - QUIT messages aren't sent for all users in a netsplit
# NICKv2 - Extended NICK command, sending MODE and CHGHOST info with it
# SID - Use UIDs and SIDs (unreal 3.4)
# VL - Sends version string in below SERVER message
# UMODE2 - used for users setting modes on themselves (one less argument needed)
# TS - Sends TS in burst to mitigate time-based desyncs.
