If you need that functionality, you must run once -with -txindex -reindex to rebuild block-chain indices (see below for more -details). - -Improvements ------------- - -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. - -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). - -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. - -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"). - -New/changed settings (command-line or bitcoin.conf file) --------------------------------------------------------- - -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. - -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. - -txindex : maintains an extra index of old, spent transaction ids so they will be found -by the getrawtransaction JSON-RPC method. Can only be set when the database is -initialized. - -reindex : rebuild block and transaction indices from the downloaded block data. - -New JSON-RPC API Features -------------------------- - -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. - -gettxout retrieves a single transaction output from the current set of unspent outputs. -Optionally, the mempool transactions are taken into account. - -gettxoutsetinfo calculates statistics about the current set of unspent outputs. - -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 ------------------- - -Qt 4.8.3 (compiling against older versions of Qt 4 should continue to work) - +Version 0.8.1 introduces a temporary block validation rule to avoid an incompatibility +with version 0.7.2 and earlier. |
