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 (https://bitcointalk.org/index.php?action=profile;u=4528) 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 (https://bitcointalk.org/index.php?action=profile;u=31239)) 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.

Thanks to everyone who worked hard on this release!

+1

Thanks!

Thank you

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

Gavin, aren't you going to post the hashes signed with your private key?

i fell in love with the gui and all the new features, nice work ppl, thank you  :D

Tits or it did not happen! Seriously, I want to see screenshots of new Bitcoin client.

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

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.

The download directory contains them in a file called SHASUMS.asc:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.0/SHASUMS.asc/download

... which I'll reproduce here just because it is easy:

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

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.

had same problem with Mac version.

wow!  only took me 1/2h to download blockchain on my Macbook Pro!

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.

Looks nice. I'm going to like it.

Thanks for your efforts...

how to start 0.5 minimized?

bitcoin-qt.exe -min
is ignored

bitcoin-qt.exe --help
bitcoin-qt.exe -?
bitcoin-qt.exe /?
also do not work

upd. (win7): right click on tray icon, left click on desktop. popup menu remains shown

Small bug (under Windows): in overview page, when I hover mouse over some recent transaction, the tooltip window appear in whole black background, preventing to see any text in it.

Also, I do not like the grid lines vertical spacing, should be smaller to be able to see more, but its probably the way how Qt shows grid. I prefer the Windows OS style spacing.

What is the purpose of wallat.dat.rewrite file?  Can I delete?

This is probably not the best place to be reporting bugs?  Entering each as a separate issue in Github would probably be helpful.

I didn't read the notes before upgrading. Just backed up my wallet and installed. It's all working fine or seems to be. I'm not worried about having been hacked. Is there anything that I could have bungled up? RTFM fail :)

shasum --check

What does it mean if an receiving address is grey and in Brackets? (in the Transaction overview)

Or if there is (k.A.) in this overview?


Should be delete/backup the wallet.dat and rename wallet.dat.rewrite -> wallet.dat? ....testing.... no that doesn't work...

PS: It doesn't matter to me, because I have about 0.0015 Bitcoins on there anymore, but I wonder....
PPS: hmm..... I try it with an unencrypted "pre 0.4 version" wallet

For those interested in this, please note that currently the ppa directs you to an outdated version. Specifically, version 0.3.24

I'm confused, the file says "bitcoin-0.5.0-win32-setup.exe" but the GUI looks the same and in the version number inside the client it says
version 0.4.0-Beta.

Hm, I just downloaded the .zip version and noticed that the sha1sum doesn't match:

From SHASUMS.asc:
97ef546d923e75f309a19f8a52b07affc0942948  bitcoin-0.5.0-win32.zip

>sha1sum.exe bitcoin-0.5.0-win32.zip
4d7a71726b39f0617066e97468cb02431bfb2b4e  bitcoin-0.5.0-win32.zip

What's up?

I updated the .zip and .tar.gz and SHASUMS.asc a few hours ago, because the .zip and the .tar.gz were expanding to a "bitcoin-rc7" directory.


Be sure you run bitcoin-qt.exe, not the old bitcoin.exe.

no it's not, just add the posted ppa and "apt-get update". I installed from there with no issues. All the dependencies too

That is the old ppa which hasnt been touched in a while, the bitcoin/bitcoin ppa has always had 0.5.

You're mistakenly referring to the old unofficial PPA https://launchpad.net/~stretch/+archive/bitcoin

The SHASUMS.asc on sourceforge hasn't been updated.

EDIT: Now it has been updated, so everything's peachy. :)

Thanks again for releasing the Mac version synchronized with the others and not making us Apple guys wait!

On my windows7 system the bitcoin-screen goes blank after a few minutes of inactivity. After some random clicking and fidgeting the screen sometimes comes backl and sometimes it doesnt. Anyone else with this problem ?

Greetz from holland!

Ah, that did it. Until I added "sudo apt-get update" all I could see is the older version. Just installed without further issue on a fresh Ubuntu 11.10 system. 

updated to 0.5.0.1-beta
Thanks!

Very nice job guys.
I wonder though what happend with the amount of confirms on transaction?
Why did you guys remove this little piece of handy information?

Edit:
Also, I get these black rectangles popping up when i hover over my recent transactions.
Not sure if its just me.

I get a green check if it's 6 confirms or more, and a "clock" icon that progresses as that trans. gets more confirms.  The exact number of confirms can be found by mousing over the check or "clock".

I like the new interface a lot.  Thanks, developers!

lot of people complain about tooltips, black rectangles in your case, not showing up correctly in ubuntu. Try changing your theme settings. It worked for me

no, its win7 too
even though the new gui is much better than the old one, it definitely asks for a 0.5.1. no biggies but a little to many small bugs. the buggy autorun setting is especially bad, since it will effectively make the network smaller.

Just did an install over a older bitcoins client, win 7

SUCKS!!!

now bitcoin client dosent work..
Program crashes now

What a great way to attract new bitcoin users..

Complain.  Bitch.  Cry.  No debug info.

What a great way to attract bug fixes for your problems.

teflone-- are you running bitcoin.exe or bitcoin-qt.exe?

The new 0.5.0, I think its qt

I fixed it by deleting the prior bitcoin folder..

the new programs opens up without an error now.. and somehow has my history, I guess it wasnt in my bitcoin folder..

now the interface is look's good  :o. i like it very much maybe add more theme would be good

I've been using it for a few days now.  A few things I didn't like at first now seem fine.

One thing still bugs me a slight bit.  I'd like to have the total balance on the transaction screen.  Right now it's only on the overview screen.

Overall, as I said before, great job.  Love to be able to sort address by address or label, love to be able to export the transaction list. Love the search transactions.

Thanks!

Nice Job! Congrats.

Sorry for slight off-topic, but is it planned to add "IMPORT/EXPORT address/private key pair" as a feature into main client? With the BitBills, Casascius Coins and paper wallets all around, this would simplify the life a lot.

Yes it would.

it's even crashed one time...

Start a new thread with debugging information so that it can be fixed.

this may have been mentioned before but after 0.5 install, i still have 0.4 opened in my system tray which i can send coins from WITH a password.  not that this is a problem, i don't think, but it is confusing that its still open and available.

i haven't figured out yet how to delete 0.4 w/o destroying the encrypted wallet yet.
