Bitcoin

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 /Applications/Bitcoin-Qt (on Mac) or 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
