The code was released on July 17 and miners have started running the new btc1 software.
It is said that the miners who supported the New York agreement are the ones currently running the codes.
The bip91 version is a combination of UASF & BIP148.
Mining pools signaling and mining BIP91 blocks include Bixin, BTC.com, ANTPOOL, Bitfury, and Bitclub so far.
