Project Description

Bitcoin is a peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.

This is another quick bugfix release, trying to deal with the influx of new bitcoin users. P2P connect-to-node logic was changed to reduce timeout a bit. The transaction fee reduced to 0.0005 for new transactions. A client will relay transactions with fees as low as 0.0001 BTC.

The client will accept and relay TX's with a 0.0005 BTC fee schedule (users still pay 0.01 BTC per kb until the next version). Non-standard transactions are accepted on testnet. Source code tree has been reorganized (prep for autotools build). The "Generate Coins" option has been removed from the GUI, and 4way SSE miner has been removed. The internal reference CPU miner remains available, but users are directed to external miners for best hash production. IRC is overflowing. Client now bootstraps to channels #bitcoin00 - #bitcoin99. DNS names now may be used with -addnode and -connect (requires -dns to enable).

Universal Plug and Play support was added. Support for full-precision bitcoin amounts. A new method of finding bitcoin nodes to connect with (via DNS A records) was added. There is a new RPC command, "sendmany", to send bitcoins to more than one address in a single transaction. There is a logtimestamps option to add a timestamp to each line in debug.log. Immature blocks (newly generated, under 120 confirmations) are now shown in listtransactions. Several bugfixes.
