Bitcoin version 0.7.0 is now available for download at:
  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.7.0/

We recommend that everybody running prior versions of bitcoind/Bitcoin-Qt
upgrade to this release, except for users running Mac OSX 10.5.

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

Project source code is hosted at github; you can get
source-only tarballs/zipballs directly from there:
  https://github.com/bitcoin/bitcoin/tarball/v0.7.0  # .tar.gz
  https://github.com/bitcoin/bitcoin/zipball/v0.7.0  # .zip

Ubuntu Linux users can use the "Personal Package Archive" (PPA)
maintained by Matt Corallo to automatically keep
bitcoin up-to-date.  Just type
  sudo apt-add-repository ppa:bitcoin/bitcoin
  sudo apt-get update
in your terminal, then install the bitcoin-qt package:
  sudo apt-get install bitcoin-qt


How to Upgrade

If you are running an older version, shut it down. Wait
until it has completely shut down (which might take a few minutes for older
versions), then run the installer (on Windows) or just copy over
Code:
/Applications/Bitcoin-Qt
(on Mac) or
Code:
bitcoind/bitcoin-qt
(on Linux).

If you were running on Linux with a version that might have been compiled
with a different version of Berkeley DB (for example, if you were using the
PPA and are switching to the binary release), then run the old version again
with the -detachdb argument and shut it down; if you do not, then the new
version will not be able to read the database files and will exit with an error.

Incompatible Changes

* Replaced the 'getmemorypool' RPC command with 'getblocktemplate/submitblock'
  and 'getrawmempool' commands.
* Remove deprecated RPC 'getblocknumber'

Bitcoin Improvement Proposals implemented

BIP 22 - 'getblocktemplate', 'submitblock' RPCs
BIP 34 - block version 2, height in coinbase
BIP 35 - 'mempool' message, extended 'getdata' message behavior


Core bitcoin handling and blockchain database

* Reduced CPU usage, by eliminating some redundant hash calculations
* Cache signature verifications, to eliminate redundant signature checks
* Transactions with zero-value outputs are considered non-standard
* Mining: when creating new blocks, sort 'paid' area by fee-per-kb
* Database: better validation of on-disk stored data
* Database: minor optimizations and reliability improvements
* -loadblock=FILE will import an external block file
* Additional DoS (denial-of-service) prevention measures
* New blockchain checkpoint at block 193,000


JSON-RPC API

* Internal HTTP server is now thread-per-connection, rather than
  a single-threaded queue that would stall on network I/O.
* Internal HTTP server supports HTTP/1.1, pipelined requests and
  connection keep-alive.
* Support JSON-RPC 2.0 batches, to encapsulate multiple JSON-RPC requests
  within a single HTTP request.
* IPv6 support
* Added raw transaction API.  See https://gist.github.com/2839617
* Added 'getrawmempool', to list contents of TX memory pool
* Added 'getpeerinfo', to list data about each connected network peer
* Added 'listaddressgroupings' for better coin control
* Rework getblock call.
* Remove deprecated RPC 'getblocknumber'
* Remove superceded RPC 'getmemorypool' (see BIP 22, above)
* listtransactions output now displays "smart" times for transactions,
  and 'blocktime' and 'timereceived' fields were added


P2P networking

* IPv6 support
* Tor hidden service support (see doc/Tor.txt)
* Attempts to fix "stuck blockchain download" problems
* Replace BDB database "addr.dat" with internally-managed "peers.dat"
  file containing peer address data.
* Lower default send buffer from 10MB to 1MB
* proxy: SOCKS5 by default
* Support connecting by hostnames passed to proxy
* Add -seednode connections, and use this instead of DNS seeds when proxied
* Added -externalip and -discover
* Add -onlynet to connect only to a given network (IPv4, IPv6, or Tor)
* Separate listening sockets, -bind=<addr>


Qt GUI

* Add UI RPC console / debug window
* Re-Enable URI handling on Windows, add safety checks and tray-notifications
* Harmonize the use of ellipsis ("...") to be used in menus, but not on buttons
* Add 2 labels to the overviewpage that display Wallet and Transaction status (obsolete or current)
* Extend the optionsdialog (e.g. language selection) and re-work it to a tabbed UI
* Merge sign/verify message into a single window with tabbed UI
* Ensure a changed bitcoin unit immediately updates all GUI elements that use units
* Update QR Code dialog
* Improve error reporting at startup
* Fine-grained UI updates for a much smoother UI during block downloads
* Remove autocorrection of 0/i in addresses in UI
* Reorganize tray icon menu into more logical order
* Persistently poll for balance change when number of blocks changed
* Much better translations
* Override progress bar design on platforms with segmented progress bars to assist with readability
* Added 'immature balance' display on the overview page
* (Windows only): enable ASLR and DEP for bitcoin-qt.exe
* (Windows only): add meta-data to bitcoin-qt.exe (e.g. description)

Internal codebase

* Additional unit tests
* Compile warning fixes


Miscellaneous

* Reopen debug.log upon SIGHUP
* Bash programmable completion for bitcoind(1)
* On supported OS's, each thread is given a useful name

Gavin, I was just wondering, would you mind explaining what this is:
* New blockchain checkpoint at block 193,000

Nvm, found an explanation here: http://bitcoin.stackexchange.com/questions/1061/can-a-51-attack-be-detected-and-dealt-with/1065#1065

Excellent. I guess the Ubuntu PPA takes some time to be ready as it doesn't seem to be showing an update available yet.

Threaded RPC server, excellent. Less memory usage is never a bad thing either.

Thank you developers!

Weird. I see it listed on the launchpad website but in Update Manager and Synaptics it only shows 0.6.3-natty2 even after reloading. Well, I guess it will show up some time.

edit: fixed err in version.

Upgrade went perfectly on Win7 32bit.

The Debug window is fantastic and "out of sync" messages really help.

Excellent work as usual. 

<PissAntComplaint>
As a colour blind DBA (i.e UI retarded), I dislike the startup logo.
I'd rather see the "traditional" Bitcoin icon on a light coloured (perhaps a gradient) background.

Yeah, logo is how big? in kilobytes? (but QT is also big, hehehe.) I prefer no pictures though and just a purely functional program, but splash screens have been pretty much standard in many apps, so thanks.

Thank you!

This time I can confirm that gitian gives me exactly the same bitcoin-qt.exe as you serve. (unlike it once was with 0.6.2)
