+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
