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 an -Ubuntu PPA version), 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. - -Explanation of -detachdb (and the new "stop true" RPC command): -The Berkeley DB database library stores data in both ".dat" and -"log" files, so the database is always in a consistent state, -even in case of power failure or other sudden shutdown. 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 + $ git shortlog --no-merges v0.7.1.. + +Incompatible Changes +-------------------- + +This release no longer maintains a full index of historical transaction ids +by default, so looking up an arbitrary transaction using the getrawtransaction +RPC call will not work. If you need that functionality, you must run once +with -txindex=1 -reindex=1 to rebuild block-chain indices (see below for more +details). + +Improvements ------------ -* Added a boolean argument to the RPC 'stop' command, if true sets - -detachdb to create standalone database .dat files before shutting down. +Mac and Windows binaries are signed with certificates owned by the Bitcoin +Foundation, to be compatible with the new security features in OSX 10.8 and +Windows 8. -* -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. This should only be used if your wallet becomes - corrupted, and is not intended to replace regular wallet backups. +LevelDB, a fast, open-source, non-relational database from Google, is +now used to store transaction and block indices. LevelDB works much better +on machines with slow I/O and is faster in general. Berkeley DB is now only +used for the wallet.dat file (public and private wallet keys and transactions +relevant to you). -* Import $DataDir/bootstrap.dat automatically, if it exists. +Pieter Wuille implemented many optimizations to the way transactions are +verified, so a running, synchronized node uses much less memory and does +much less I/O. He also implemented parallel signature checking, so if you +have a multi-CPU machine all CPUs will be used to verify transactions. -Dependency changes ------------------- +New Features +------------ + +"Bloom filter" support in the network protocol for sending only relevant transactions to +lightweight clients. + +contrib/verifysfbinaries is a shell-script to verify that the binary downloads +at sourceforge have not been tampered with. If you are able, you can help make +everybody's downloads more secure by running this occasionally to check PGP +signatures against download file checksums. + +contrib/spendfrom is a python-language command-line utility that demonstrates +how to use the "raw transactions" JSON-RPC api to send coins received from particular +addresses (also known as "coin control"). -* Qt 4.8.2 for Windows builds +New/changed settings (command-line or bitcoin.conf file) +-------------------------------------------------------- -* openssl 1.0.1c +dbcache : now controls LevelDB memory usage. Running with (for example) -dbcache=1000 +will use a gigabyte of memory and might make the initial blockchain download faster. -Bug fixes ---------- +par : controls how many threads to use to validate transactions. Defaults to the number +of CPUs on your machine, use -par=1 to limit to a single CPU. -* When running -testnet, use RPC port 18332 by default. +txindex : maintains an extra index of old, spent transaction ids so they will be found +by the getrawtransaction JSON-RPC method. -* Better detection and handling of corrupt wallet.dat and blkindex.dat files. - Previous versions would crash with a DB_RUNRECOVERY exception, this - version detects most problems and tells you how to recover if it - cannot recover itself. +reindex : rebuild block and transaction indices from the downloaded block data. -* Fixed an uninitialized variable bug that could cause transactions to - be reported out of order. +New JSON-RPC API Features +------------------------- -* Fixed a bug that could cause occasional crashes on exit. +lockunspent / listlockunspent allow locking transaction outputs for a period of time so +they will not be spent by other processes that might be accessing the same wallet. + +addnode / getaddednodeinfo methods, to connect to specific peers without restarting. + +importprivkey now takes an optional boolean parameter (default true) to control whether +or not to rescan the blockchain for transactions after importing a new private key. + +Important Bug Fixes +------------------- + +Privacy leak: the position of the "change" output in most transactions was not being +properly randomized, making network analysis of the transaction graph to identify +users' wallets easier. + +Zero-confirmation transaction vulnerability: accepting zero-confirmation transactions +(transactions that have not yet been included in a block) from somebody you do not +trust is still not recommended, because there will always be ways for attackers to +double-spend zero-confirmation transactions. However, this release includes a bug +fix that makes it a little bit more difficult for attackers to double-spend a +certain type ("lockTime in the future") of zero-confirmation transaction. + +Dependency Changes +------------------ -* Warn the user that they need to create fresh wallet backups after they - encrypt their wallet. +Qt 4.8.3 (compiling against older versions of Qt 4 should continue to work) diff --git a/doc/release-process.txt b/doc/release-process.txt index 708e320659..166f2aaf3c 100644 --- a/doc/release-process.txt +++ b/doc/release-process.txt @@ -5,6 +5,7 @@ src/clientversion.h (change CLIENT_VERSION_IS_RELEASE to true) share/setup.nsi doc/README* + contrib/verifysfbinaries/verify.sh * tag version in git |
