Changes:

- The increase = in the maximum block sigops after HF has been documented.
- Comme= nts added about the worst case block size.

Happy w= eekend! And don't forget to start signaling something before block 4757= 76 !=C2=A0 It's just 90 blocks away.
Bit 1 or 4,1 or whatever= you wish, but please signal something.

To the moo= n!

Good news!

Code to support 2x (the hard fork part of the proposal) has been out and tested for much longer than that.

Not true. It's different = code on top of segwit. The first attempt in btc1 (very recent) didn't e= ven increased the size (because it changed the meaningless "base size&= quot; without touching the weight limit.
