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.

now i get it crystal clear man, so its like a tree that starts from one person a makes lots of branches. So if someone deletes contents he and his "followers" will see it as deleted but not the rest of the members, part of other branches... hope i got it well this time  

tl;dr on how the database maintains its integrity?

There's not much documentation and the source isn't public, but it doesn't seem very anonymous or robust to me.

Right, so it essentially just lets you create a forum (or whatever) that can't be shut down?  

Can someone explain the benefit of using this?  Not sure I get it
