This manual is for ubuntu, not sure if it will also work for windows. But yes, its still up to date, I'll update if something changes.

The miner patch might also be useful for experienced miners. It provides some extra hashes on top of the gmp patch!

As for this hardfork, its documented in the sourcecode: Nothing else was changed, no censorship, just these accounts.

I'm kinda pissed because I didn't know what happened. I thought I messed up the key change and spent hours searching for the (not existing) key. A little note, for example on the steemit.com account page

I recently wondered what happened to my account bu328281. It has over 2 million VESTS and some STEEM in it. I just didn't have the key to it in my wallet. Spent some hours searching for the key, but nothing.
