A few minutes ago, at 14:00:00 UTC, Hard Fork 25 was triggered!
I ( @someguy123 ) produced the 6th block (4th one in the log was @aggroed who's temporarily producing on my node as he was unable to get a HF25 node up in time), and the lucky @arcange produced the 1st HF25 block :)
So far no problems, and hopefully everything runs smoothly, but users may notice minor issues across some platforms over the following days, as some RPC nodes may not be ready yet, and certain applications may need to be updated to support to HF25.
