-Bitcoin Core version 0.9.0rc1 is now available from:
-
- http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0rc1/
-
-This is a release candidate for a new major version. 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.
-
-`walletpassphrase` RPC
------------------------
-
-The behavior of the `walletpassphrase` RPC when the wallet is already unlocked
-has changed between 0.8 and 0.9.
-
-The 0.8 behavior of `walletpassphrase` is to fail when the wallet is already unlocked:
-
- > walletpassphrase 1000
- walletunlocktime = now + 1000
- > walletpassphrase 10
- Error: Wallet is already unlocked (old unlock time stays)
-
-The new behavior of `walletpassphrase` is to set a new unlock time overriding
-the old one:
-
- > walletpassphrase 1000
- walletunlocktime = now + 1000
- > walletpassphrase 10
- walletunlocktime = now + 10 (overriding the old unlock time)
-

-=======================
-
-RPC:
-
-- 'listreceivedbyaddress' now provides tx ids
-- Updated help and tests for 'getreceivedby(account|address)'

-- 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:

-- 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

-

-- Optimize rescan to skip blocks prior to birthday
-- Let user select wallet file with -wallet=foo.dat
-- Consider generated coins mature at 101 instead of 120 blocks
-- Improve wallet load time
-- Don't count txins for priority to encourage sweeping
-- Don't create empty transactions when reading a corrupted wallet
-- Fix rescan to start from beginning after importprivkey
-- Only create signatures with low S values.
-
-Mining:
-
-- Increase default -blockmaxsize/prioritysize to 750K/50K

-
-Build system:
-

-- Solaris compatibility fixes
-- Check integrity of gitian input source tarballs

-- Add Coin Control Features
-- Improve receive coins workflow: make the 'Receive' tab into a form to request
