The shorter keys are already supported +by the network but wallet.dat files containing +short keys are not compatible with earlier +versions of Bitcoin-Qt/bitcoind. + +New command-line argument -blocknotify= +that will spawn a shell process to run +when a new block is accepted. + +New command-line argument -splash=0 to disable +Bitcoin-Qt's initial splash screen + +validateaddress JSON-RPC api command output includes +two new fields for addresses in the wallet: + pubkey : hexadecimal public key + iscompressed : true if pubkey is a short 33-byte key + +New JSON-RPC api commands for dumping/importing +private keys from the wallet (dumprivkey, importprivkey). + +New JSON-RPC api command for getting information about +blocks (getblock, getblockhash). + +New JSON-RPC api command (getmininginfo) for getting +extra information related to mining. The getinfo +JSON-RPC command no longer includes mining-related +information (generate/genproclimit/hashespersec). + + + +NOTABLE CHANGES +--------------- + +BIP30 implemented (security fix for an attack involving +duplicate "coinbase transactions"). + +The -nolisten, -noupnp and -nodnsseed command-line +options were renamed to -listen, -upnp and -dnsseed, +with a default value of 1. The old names are still +supported for compatibility (so specifying -nolisten +is automatically interpreted as -listen=0; every +boolean argument can now be specified as either +-foo or -nofoo). + +The -noirc command-line options was renamed to +-irc, with a default value of 0. Run -irc=1 to +get the old behavior. + +Three fill-up-available-memory denial-of-service +attacks were fixed. + +NOT YET IMPLEMENTED FEATURES +---------------------------- + +Support for clicking on bitcoin: URIs and +opening/launching Bitcoin-Qt is available only on Linux, +and only if you configure your desktop to launch +Bitcoin-Qt. All platforms support dragging and dropping +bitcoin: URIs onto the Bitcoin-Qt window to start +payment. + + +PRELIMINARY SUPPORT FOR MULTISIGNATURE TRANSACTIONS +--------------------------------------------------- + +This release has preliminary support for multisignature +transactions-- transactions that require authorization +from more than one person or device before they +will be accepted by the bitcoin network. + +Prior to this release, multisignature transactions +were considered 'non-standard' and were ignored; +with this release multisignature transactions are +considered standard and will start to be relayed +and accepted into blocks. + +It is expected that future releases of Bitcoin-Qt +will support the creation of multisignature transactions, +once enough of the network has upgraded so relaying +and validating them is robust. + +For this release, creation and testing of multisignature +transactions is limited to the bitcoin test network using +the "addmultisigaddress" JSON-RPC api call. + +Short multisignature address support is included in this +release, as specified in BIP 13 and BIP 16. + + +Thanks to everybody who contributed to this release: + +- Alex B +- Alistair Buxton +- Chris Moore +- Clark Gaebel +- Daniel Folkinshteyn +- Dylan Noblesmith +- Forrest Voight +- Gavin Andresen +- Gregory Maxwell +- Janne Pulkkinen +- Joel Kaartinen +- Lars Rasmusson +- Luke Dashjr +- Matt Corallo +- Michael Ford +- Michael Hendricks +- Nick Bosma +- Nils Schneider +- Philip Kaufmann +- Pierre Pronchery +- Pieter Wuille +- Rune K Svendsen +- Wladimir J. van der Laan +- coderrr +- p2k +- sje397 + +Special thanks to Sergio Lerner and Matt Corallo for bringing +potential denial-of-service attacks to our attention. diff --git a/_releases/2012-05-04-v0.6.1.md b/_releases/2012-05-04-v0.6.1.md index 5820776b..baeb19b4 100644 --- a/_releases/2012-05-04-v0.6.1.md +++ b/_releases/2012-05-04-v0.6.1.md @@ -2,10 +2,67 @@ title: Bitcoin-Qt version 0.6.1 released --- Bitcoin-Qt version 0.6.1 is now available for download at: - + This is a bug-fix and code-cleanup release, with no major new features. -Please report bugs using the issue tracker at GitHub: - +NOTABLE CHANGES +=============== +Much faster shutdowns.

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 : controls LevelDB memory usage. + +par : controls how many threads to use to validate transactions.

A new block-acceptance rule that will be enforced from 21 March 2013 until +15 May 2013 to prevent accepting blocks that fail to validate on pre-0.8 peers. + +2. A new compiled-in checkpoint at block number 225,430 -- the first block +of the 11 March 2013 chain fork. + + +0.8.0 Release notes +=================== + +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 +------------ + +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 less working 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 : controls LevelDB memory usage. + +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. + +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. + +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) + + +Thanks to everybody who contributed to the 0.8.0 release: +--------------------------------------------------------- + +- Alexander Kjeldaas +- Andrey Alekseenko +- Arnav Singh +- Christian von Roques +- Eric Lombrozo +- Forrest Voight +- Gavin Andresen +- Gregory Maxwell +- Jeff Garzik +- Luke Dashjr +- Matt Corallo +- Mike Cassano +- Mike Hearn +- Peter Todd +- Philip Kaufmann +- Pieter Wuille +- Richard Schwab +- Robert Backhaus +- Rune K.

This change is not an endorsement of storing data in the +blockchain. The OP_RETURN change creates a provably-prunable output, +to avoid data storage schemes -- some of which were already deployed -- +that were storing arbitrary data such as images as forever-unspendable +TX outputs, bloating bitcoin's UTXO database. + +Storing arbitrary data in the blockchain is still a bad idea; it is less +costly and far more efficient to store non-currency data elsewhere. + +Autotools build system +----------------------- + +For 0.9.0 we switched to an autotools-based build system instead of individual +(q)makefiles. + +Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and +bitcoind makes it easier for experienced open source developers to contribute +to the project. + +Be sure to check doc/build-*.md for your platform before building from source. + +Bitcoin-cli +------------- + +Another change in the 0.9 release is moving away from the bitcoind executable +functioning both as a server and as a RPC client.

During periods of heavy transaction volume, even this +fee may not be enough to get transactions confirmed quickly; the mintxfee +option may be used to override the default. + +0.9.0 Release notes +======================= + +RPC: + +- New notion of 'conflicted' transactions, reported as confirmations: -1 +- 'listreceivedbyaddress' now provides tx ids +- Add raw transaction hex to 'gettransaction' output +- Updated help and tests for 'getreceivedby(account|address)' +- In 'getblock', accept 2nd 'verbose' parameter, similar to getrawtransaction, + but defaulting to 1 for backward compatibility +- Add 'verifychain', to verify chain database at runtime +- Add 'dumpwallet' and 'importwallet' RPCs +- 'keypoolrefill' gains optional size parameter +- Add 'getbestblockhash', to return tip of best chain +- Add 'chainwork' (the total work done by all blocks since the genesis block) + to 'getblock' output +- Make RPC password resistant to timing attacks +- Clarify help messages and add examples +- Add 'getrawchangeaddress' call for raw transaction change destinations +- Reject insanely high fees by default in 'sendrawtransaction' +- Add RPC call 'decodescript' to decode a hex-encoded transaction script +- Make 'validateaddress' provide redeemScript +- Add 'getnetworkhashps' to get the calculated network hashrate +- New RPC 'ping' command to request ping, new 'pingtime' and 'pingwait' fields + in 'getpeerinfo' output +- Adding new 'addrlocal' field to 'getpeerinfo' output +- Add verbose boolean to 'getrawmempool' +- Add rpc command 'getunconfirmedbalance' to obtain total unconfirmed balance +- Explicitly ensure that wallet is unlocked in `importprivkey` +- Add check for valid keys in `importprivkey` + +Command-line options: + +- New option: -nospendzeroconfchange to never spend unconfirmed change outputs +- New option: -zapwallettxes to rebuild the wallet's transaction information +- Rename option '-tor' to '-onion' to better reflect what it does +- Add '-disablewallet' mode to let bitcoind run entirely without wallet (when + built with wallet) +- Update default '-rpcsslciphers' to include TLSv1.2 +- make '-logtimestamps' default on and rework help-message +- RPC client option: '-rpcwait', to wait for server start +- Remove '-logtodebugger' +- Allow `-noserver` with bitcoind + +Block-chain handling and storage: + +- Update leveldb to 1.15 +- Check for correct genesis (prevent cases where a datadir from the wrong + network is accidentally loaded) +- Allow txindex to be removed and add a reindex dialog +- Log aborted block database rebuilds +- Store orphan blocks in serialized form, to save memory +- Limit the number of orphan blocks in memory to 750 +- Fix non-standard disconnected transactions causing mempool orphans +- Add a new checkpoint at block 279,000 + +Wallet: + +- Bug fixes and new regression tests to correctly compute + the balance of wallets containing double-spent (or mutated) transactions +- Store key creation time.
