Anyone that has an old wallet.dat from early Bitcoin-qt days has tested it by the way? Any problems?

Do legacy and segwit addresses show up fine the GUI? got some screenshots to see how it looks like? I can't install it currently, im out and will not be back home for a while.

The old wallet loaded OK but it is empty so I couldn't test beyond that. To use Segwit you need a new wallet anyway so I renamed that and it made a new Segwit one automatically. Getting a new receiving address give a Segwit one start '3'. I'm still trying to work out how to get a bech32 address.

Edit: Official release thread has appeared https://bitcointalk.org/index.php?topic=3024763.0


Well I remember reading achow101 saying that if you had an old bitcoin-qt wallet.dat and opened it with 0.16 it will automatically convert it to the new format and you don't need to do anything annoying like creating an empty one and sending all of your coins over the new wallet.dat which is hell.

And also I got some coins on a bech32 electrum address, I've read I can't export it because it will not work properly... when this will be fixed?

I guess I will leave them on electrum's wallet for the time being.

Im also still paranoid about the new format. I assume the seed is impossible to see and therefore safer than electrum's hd format right?

What do you mean "impossible to see"? The seed still has to be stored in the encrypted wallet.dat

As far as I know, in Bitcoin Core is impossible to show the seed of the wallet for security reasons, while in Electrum is very easy to show the seed and it is shown even in the wizard when creating a wallet. Maybe there is a way to show it with Bitcoin Core on the command line, but I hope not, since it's pretty stupid, I think it just adds an huge exploit possibility. A hacker gets your seed and he gets all future addresses you create... not fun. I would never feel safe that way. Also seed derivation was possible with Electrum if you had a master public key and some other keys I think... im just too paranoid to even bother and I stick to the basics.

Im going to get rid of Electrum as soon as I install 0.16. If I can't import the keys I guess I will need to send the coins to myself.
