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:

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:







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.

potential denial-of-service attacks to our attention.
