The +format of the ".dat" files is portable between different +versions of Berkeley DB, but the "log" files are not-- even minor +version differences may have incompatible "log" files. The +-detachdb option moves any pending changes from the "log" files +to the "blkindex.dat" file for maximum compatibility, but makes +shutdown much slower. Note that the "wallet.dat" file is always +detached, and versions prior to 0.6.0 detached all databases +at shutdown. + +New features ------------ -* 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 gettransaction, getblock calls. 'gettransaction' responds for - non-wallet TXs now. -* Remove deprecated RPC 'getblocknumber' -* Remove superceded RPC 'getmemorypool' (see BIP 22, above) -* listtransactions output now displays "smart" times for transactions, - and 'blocktime' and 'timereceived' fields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 and version) - -Internal codebase ------------------ -* Additional unit tests -* Compile warning fixes - - -Miscellaneous -------------- -* Reopen debug.log upon SIGHUP -* Bash programmable completion for bitcoind(1) -* On supported OSes, each thread is given a useful name + +* Added a boolean argument to the RPC 'stop' command, if true sets + -detachdb to create standalone database .dat files before shutting down. + +* -salvagewallet command-line option, which moves any existing wallet.dat + to wallet.{timestamp}.dat and then attempts to salvage public/private + keys and master encryption keys (if the wallet is encrypted) into + a new wallet.dat.
