Bitcoin-Qt/bitcoind version 0.5.0

[Gavin Andresen]

Bitcoin version 0.5.0 is now available for download at:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.0/

The major change for this release is a completely new graphical interface that uses the Qt user interface toolkit.

This release include German, Spanish, Spanish-Castilian, Norwegian and Dutch translations. More translations are welcome; join the project at Transifex if you can help:

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

For Ubuntu users, there is a new 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.

MAJOR BUG FIX  (CVE-2011-4447)

The wallet encryption feature introduced in Bitcoin version 0.4.0 did not sufficiently secure the private keys. An attacker who
managed to get a copy of your encrypted wallet.dat file might be able to recover some or all of the unencrypted keys and steal the
associated coins.

If you have a previously encrypted wallet.dat, the first time you run bitcoin-qt or bitcoind the wallet will be rewritten, Bitcoin will
shut down, and you will be prompted to restart it to run with the new, properly encrypted file.

If you had a previously encrypted wallet.dat that might have been copied or stolen (for example, you backed it up to a public
location) you should send all of your bitcoins to yourself using a new bitcoin address and stop using any previously generated addresses.

Wallets encrypted with this version of Bitcoin are written properly.

Technical note: the encrypted wallet's 'keypool' will be regenerated the first time you request a new bitcoin address; to be certain that the
new private keys are properly backed up you should:

1. Run Bitcoin and let it rewrite the wallet.dat file

2. Run it again, then ask it for a new bitcoin address.
 Bitcoin-Qt: Address Book, then New Address...
 bitcoind: run the 'walletpassphrase' RPC command to unlock the wallet,  then run the 'getnewaddress' RPC command.

3. If your encrypted wallet.dat may have been copied or stolen, send  all of your bitcoins to the new bitcoin address.

4. Shut down Bitcoin, then backup the wallet.dat file.
 IMPORTANT: be sure to request a new bitcoin address before backing up, so that the 'keypool' is regenerated and backed up.

"Security in depth" is always a good idea, so choosing a secure location for the backup and/or encrypting the backup before uploading it is recommended. And as in previous releases, if your machine is infected by malware there are several ways an attacker might steal your bitcoins.

Thanks to Alan Reiner (etotheipi) for finding and reporting this bug.

MAJOR GUI CHANGES

"Splash" graphics at startup that show address/wallet/blockchain loading progress.

"Synchronizing with network" progress bar to show block-chain download progress.

Icons at the bottom of the window that show how well connected you are to the network, with tooltips to display details.

Drag and drop support for bitcoin: URIs on web pages.

Export transactions as a .csv file.

Many other GUI improvements, large and small.

RPC CHANGES

getmemorypool : new RPC command, provides everything needed to construct a block with a custom generation transaction and submit a solution

listsinceblock : new RPC command, list transactions since given block

signmessage/verifymessage : new RPC commands to sign a message with one of your private keys or verify that a message signed by the private key associated with a bitcoin address.

GENERAL CHANGES

Faster initial block download.

Up and running !

Only complaint is that when in the Options (on Windows 7x64), when checking "Start Bitcoin on windows system startup" and then hitting Apply. There's a slight locking up of the program, then the box becomes unchecked.  I'm not sure it's actually doing anything.  Hitting Ok instead of Apply, yields the same results, except the Options dialog disappears and the checkbox is still checked.  When you re-open Options, the checkbox isn't checked anymore.

Might be something to look into

Seems for me like UAC preventing creation of startup entries since the Bitcoin is not Run As Administrator...

Will soon install 0.5.0 myself to check out new version and interface. And Thanks to Gavin and all other contributors for this new release!

I was thinking the same thing and after running as admin, the checkbox is still acting as described above.  Non-working.

Use sysinternals to check where it is trying to create the startup entry. I'm busy right now with other things, tomorrow I will take a closer look on new bitcoin version

you gotta be kidding me haha, to much features to start making shots

[evoorhees]

Gavin and Dev team, thank you!!!!

0.5 is excellent. THIS is the client the world needed. Love the payment notifications in Windows, the lock/connections/status icons, and the splash screen with progress indicator. Really great work. Sincere thanks.

The new interface can have my babies.

downloaded 0.5.0 win32 setup.exe for Windows 7.

interestingly, it forced me to use not my current password but my previous and original password for the wallet.

having same problem

[David M]

Nicely done!   Kudos to all the contributors.

The "Overview" looks great.
The status bar icons are good.

The client successfully re-wrote my wallet file and ask for a restart.

I only found one interface issue.

On the Send Window: The "Clear All" button does not have a tooltip.

Functionality issue:

I noticed that it requires the passphrase to create a new address.
This seems excessive and adds several seconds of time to create a new address as I have to extract the password from KeePass.


Once again, great job Gavin and all the coders and testers.

Would not be better to sign each file individually with gpg so I can check it. Now I need to first check the checksum of file and then I need to check the signature of checksum message to see if the message is valid and then compare the two checksums by eye. It's like scratching the right ear with left hand.
