Bitcoin version 0.6.0 is now available for download at: @p{brk}
  @s{(link)} @p{par}

This release includes more than 20 language localizations. @p{brk}
More translations are welcome; join the @p{brk}
project at Transifex to help: @p{brk}
  @s{(link)} @p{par}

Please report bugs using the issue tracker at github: @p{brk}
  @s{(link)} @p{par}

Project source code is hosted at github; we are no longer @p{brk}
distributing .tar.gz files here, you can get them @p{brk}
directly from github: @p{brk}
 @s{(link)}  # .tar.gz @p{brk}
 @s{(link)}  # .zip @p{par}

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

KNOWN ISSUES @p{brk}
@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-} @p{par}

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

 @p{brk}
NEW FEATURES SINCE BITCOIN VERSION 0.5 @p{brk}
@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{--} @p{par}

Initial network synchronization should be much faster @p{brk}
(one or two hours on a typical machine instead of ten or more @p{brk}
hours). @p{par}

Backup Wallet menu option. @p{par}

Bitcoin-Qt can display and save QR codes for sending @p{brk}
and receiving addresses. @p{par}

New context menu on addresses to copy/edit/delete them. @p{par}

New Sign Message dialog that allows you to prove that you @p{brk}
own a bitcoin address by creating a digital @p{brk}
signature. @p{par}

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

New command-line argument -blocknotify=@p{lt}command@s{gt} @p{brk}
that will spawn a shell process to run @p{lt}command@s{gt}  @p{brk}
when a new block is accepted. @p{par}

New command-line argument -splash=0 to disable @p{brk}
Bitcoin-Qt's initial splash screen @p{par}

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

New JSON-RPC api commands for dumping/importing @p{brk}
private keys from the wallet (dumprivkey, importprivkey). @p{par}

New JSON-RPC api command for getting information about @p{brk}
blocks (getblock, getblockhash). @p{par}

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

 @p{par}

NOTABLE CHANGES @p{brk}
@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-} @p{par}

BIP30 implemented (security fix for an attack involving @p{brk}
duplicate "coinbase transactions"). @p{par}

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

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

Three fill-up-available-memory denial-of-service @p{brk}
attacks were fixed. @p{par}

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

 @p{brk}
PRELIMINARY SUPPORT FOR MULTISIGNATURE TRANSACTIONS @p{brk}
@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-}@p{@p{--}-} @p{par}

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

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

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

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

Short multisignature address support is included in this @p{brk}
release, as specified in BIP 13 and BIP 16. @p{par}

potential denial-of-service attacks to our attention. @p{brk}
