Bitcoin version 0.6.0 is now available for download at:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.0/test/

This release includes more than 20 language localizations.
More translations are welcome; join the
project at Transifex to help:
  https://www.transifex.net/projects/p/bitcoin/

Please report bugs using the issue tracker at github:
  https://github.com/bitcoin/bitcoin/issues

Project source code is hosted at github; we are no longer
distributing .tar.gz files here, you can get them
directly from github:
 https://github.com/bitcoin/bitcoin/tarball/v0.6.0  # .tar.gz
 https://github.com/bitcoin/bitcoin/zipball/v0.6.0  # .zip

For Ubuntu users, there is a ppa maintained by Matt Corallo which
you can add to your system so that it will automatically keep
bitcoin up-to-date.  Just type
 sudo apt-add-repository ppa:bitcoin/bitcoin
in your terminal, then install the bitcoin-qt package.


KNOWN ISSUES
------------

Shutting down while synchronizing with the network
(downloading the blockchain) can take more than a minute,
because database writes are queued to speed up download
time.


NEW FEATURES SINCE BITCOIN VERSION 0.5
--------------------------------------

Initial network synchronization should be much faster
(one or two hours on a typical machine instead of ten or more
hours).

Backup Wallet menu option.

Bitcoin-Qt can display and save QR codes for sending
and receiving addresses.

New context menu on addresses to copy/edit/delete them.

New Sign Message dialog that allows you to prove that you
own a bitcoin address by creating a digital
signature.

New wallets created with this version will
use 33-byte 'compressed' public keys instead of
65-byte public keys, resulting in smaller
transactions and less traffic on the bitcoin
network. The shorter keys are already supported
by the network but wallet.dat files containing
short keys are not compatible with earlier
versions of Bitcoin-Qt/bitcoind.

New command-line argument -blocknotify=<command>
that will spawn a shell process to run <command>
when a new block is accepted.

New command-line argument -splash=0 to disable
Bitcoin-Qt's initial splash screen

validateaddress JSON-RPC api command output includes
two new fields for addresses in the wallet:
 pubkey : hexadecimal public key
 iscompressed : true if pubkey is a short 33-byte key

New JSON-RPC api commands for dumping/importing
private keys from the wallet (dumprivkey, importprivkey).

New JSON-RPC api command for getting information about
blocks (getblock, getblockhash).

New JSON-RPC api command (getmininginfo) for getting
extra information related to mining. The getinfo
JSON-RPC command no longer includes mining-related
information (generate/genproclimit/hashespersec).



NOTABLE CHANGES
---------------

BIP30 implemented (security fix for an attack involving
duplicate "coinbase transactions").

The -nolisten, -noupnp and -nodnsseed command-line
options were renamed to -listen, -upnp and -dnsseed,
with a default value of 1. The old names are still
supported for compatibility (so specifying -nolisten
is automatically interpreted as -listen=0; every
boolean argument can now be specified as either
-foo or -nofoo).

The -noirc command-line options was renamed to
-irc, with a default value of 0. Run -irc=1 to
get the old behavior.

Three fill-up-available-memory denial-of-service
attacks were fixed.

NOT YET IMPLEMENTED FEATURES
----------------------------

Support for clicking on bitcoin: URIs and
opening/launching Bitcoin-Qt is available only on Linux,
and only if you configure your desktop to launch
Bitcoin-Qt. All platforms support dragging and dropping
bitcoin: URIs onto the Bitcoin-Qt window to start
payment.


PRELIMINARY SUPPORT FOR MULTISIGNATURE TRANSACTIONS
---------------------------------------------------

This release has preliminary support for multisignature
transactions-- transactions that require authorization
from more than one person or device before they
will be accepted by the bitcoin network.

Prior to this release, multisignature transactions
were considered 'non-standard' and were ignored;
with this release multisignature transactions are
considered standard and will start to be relayed
and accepted into blocks.

It is expected that future releases of Bitcoin-Qt
will support the creation of multisignature transactions,
once enough of the network has upgraded so relaying
and validating them is robust.

For this release, creation and testing of multisignature
transactions is limited to the bitcoin test network using
the "addmultisigaddress" JSON-RPC api call.

Short multisignature address support is included in this
release, as specified in BIP 13 and BIP 16.

Btw, I would caution against saying "Signing messages ... to prove that you own an bitcoin address ...".  It's very difficult for someone to say "prove you own this address" and then you can do so.  A MITM could ask the person who really does own the address to prove they own it then forward the response packet to the original requestor as if they owned it themselves.  There are ways to do it, but it is not likely to be executed properly, by hand.

I recommend promoting the feature as "Message signing, with address-based authentication" or something more PR-friendly.  For instance, you need a shipping address to send the 1,000 BTC merchandise that was paid for [partly] with address X.  You would instead ask for a shipping address signed by address X.  The MITM wants to divert the package to his own location, but can't do so without breaking the signature.

The important part is that the same person who owns X approves of the message that was being signed, without regards for where the person is or when they signed it.

Perhaps that's already in your line of thinking, but I think it's a distinction worth making.

The address signing is counteranonymous and against initial goals of Bitcoin. QR codes are not used worldwide and will fall in disuse much faster than IrDA links did. I smell feature bloat.

I'm not sure I follow how it is counteranonymous.  You fund a website/service with 20 BTC coming from address X.  You can then manage your account over the internet without ever creating a username/password, supplying name or email address.   The only thing that matters to the web service is that the same person who originally sent them 20 BTC is the same person telling them to transfer it to another address, purchase something, buy into a poker game, etc. 

It has the same security and anonymity features as Bitcoin itself.  For now, such messages might have to be manually constructed, but in the future, your BTC private key could be used to initiate SSL connections, etc.

Could not install on a Nordic windows7 32bit when logged in as a non admin, tried twice.
The third time I changed the installer directory to "program" instead of "program files" and it worked.

However a casual computer user will having problem will not figure that out.
If its possible to fix it would probably be good.

Really great work guys!

When the maintainer (Matt) has a little time.

No, not yet. Anybody know if there's a web page that will do the verification?  (would be easy to create one...)

It's pretty easy to disable support for that one, during compile time ... so if it's a sucker it's not hard to remove support for it Wink.

@Gavin: The linked version has still the Beta flag in the version string, perhaps you forgot to re-label it.

Gavin,

I put a sign&verify GUI into Armory, and used a BIP-10-like format to create and verify "signature blocks." 

Here is an example of the signature block and the user interface. The UI needs to be cleaned up a bit, but it does work.

Unfortunately, I am not yet compatible with the Satoshi client and I suspect I'll need to handle compressed public keys to do so.  But I want to get it compatible as soon as I can, so can you make sure that it is documented so I can match?  You also might consider a similar "signature block" technique (or do you already have it?)

Just upgraded, and it seems to be stuck at 8 connections even though port 8333 is open. Version 0.5.3.1 under same settings worked fine. Any ideas?

False alarm - after 5 minutes or so it started going up.
