Important: You MUST upgrade your BitCoinJ based software before February 20th

[Mike Hearn]

When originally implementing the connection setup code, I overlooked the fact that the Bitcoin protocol bizarrely changes itself on February 20th 2012 in a backwards incompatible manner. This means you need to apply the following commit to your copy of BitCoinJ:

http://code.google.com/p/bitcoinj/source/detail?r=8be3a7a027566676732e32298da479368952c07a

Otherwise you will lose the ability to connect to the network after that date.

I'm really sorry about this. The change is straightforward and should apply without merge conflicts. To use it on quite old copies of the library you'll need to apply it to NetworkConnection.java instead of TCPNetworkConnection.java

Hi Mike,
Just putting that new TCPNetworkConnection into MultiBit.

I believe I am right in saying that it has gone into the bitcoinj Maven
artifact with version:
0.4-SNAPSHOT

and not the 0.3 version

(That is fine by me - I just did not want anyone else to miss the
update)

That's right. Anyone not using HEAD will need to backport the patch.

We could re-spin 0.3 with the change. I'm just not sure it's worth it. As far as I know, most users of BitCoinJ track HEAD pretty closely.

I would strongly counsel against re-jigging an earlier release. There is no guarantee that people will pull down the updated version and it would cause confusion ("So which version of version 0.3 is the version with the right version protocol?").

The best way to be sure is to release the changes under 0.4 and issue a general update on the forums and mailing list.

[Mike Hearn]

It's not clear 0.4 will be out before Feb 20th. A 0.3.1 release wouldn't be that confusing, but as I said, probably not that helpful either.

Version 0.3.1 would be fine, and is the better way to go if 0.4 won't be released.

I'm just against reworking 0.3.

Thanks, I just released Bitcoin Wallet 1.48.1 to the Android Market.

Instead of going forward and update to BitCoinJ head, I decided to
branch and do a maintenance release with some cherry-picked fixes. This
was mainly because I wanted to prove to myself that I actually can do
urgent maintenance releases.

Excellent, thanks for being so fast. Hopefully after a month everyone who cares has updated.
