So, does anyone know if the dev team has to decided to officially implement the HF to the ~16th which is when the determined block would roll around or to change the block # so that it happens on the 21st as was advertised for quite some time?
HF happens by the block which is hard coded in the daemon, the date is just an estimation. The block has to be determined 6 months in advance so if there is huge increase in hashrate, it is possible for that block to come sooner than expected.
