A major version brings +both new features and bug fixes. + +Please report bugs using the issue tracker at github: + + https://github.com/bitcoin/bitcoin/issues + +How to Upgrade +-------------- + +If you are running an older version, shut it down. Wait until it has completely +shut down (which might take a few minutes for older versions), uninstall all +earlier versions of Bitcoin, then run the installer (on Windows) or just copy +over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). + +If you are upgrading from version 0.7.2 or earlier, the first time you run +0.9.0 your blockchain files will be re-indexed, which will take anywhere from +30 minutes to several hours, depending on the speed of your machine. + +On Windows, do not forget to uninstall all earlier versions of the Bitcoin +client first, especially if you are switching to the 64-bit version. + +Windows 64-bit installer +------------------------- + +New in 0.9.0 is the Windows 64-bit version of the client. There have been +frequent reports of users running out of virtual memory on 32-bit systems +during the initial sync. Because of this it is recommended to install the +64-bit version if your system supports it. + +Rebranding to Bitcoin Core +--------------------------- + +To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we +have renamed the reference client to Bitcoin Core. + +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. The RPC client functionality +(“tell the running bitcoin daemon to do THIS”) was split into a separate +executable, 'bitcoin-cli'. The RPC client code will eventually be removed from +bitcoind, but will be kept for backwards compatibility for a release or two. + +0.9.0rc1 Release notes +======================= + +RPC: + +- 'listreceivedbyaddress' now provides tx ids +- 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: + +- 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: + +- Store key creation time.
