🗒️ Summary of this message: Matt Corallo wants to release version 0.3.24 of Bitcoin as soon as possible, and is asking for agreement on two possible solutions to a problem.
📝 Original message:Despite this being quick, I really want to get 0.3.24 out and rolling so
that we have us much lead time on 0.4 as possible so that any solution
to this problem that is better in 0.3.24 can be in as many hands as
possible, and so that the network issues can be resolved.
All that needs to happen for that is to agree on either
https://github.com/bitcoin/bitcoin/pull/378 or
https://github.com/bitcoin/bitcoin/pull/381 thus, I would ask that we
get acks on those and then continue this discussion. Frankly, I prefer
378 as it is simpler and means that you dont have to keep track of what
features you have or have not used in a wallet, but instead just write
and let the keys take care of themselves. However, I'm game for either,
I just want to get 0.3.24 out the door ASAP (ie preferably rc2 tomorrow
and release by the end of the week).
