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:







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

* 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
