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.



NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP

and the SHA256SUMS.asc file to make sure your binaries are correct.

In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.



OSX 10.5 / 32-bit no longer supported

-------------------------------------



0.9.0 drops support for older Macs. The minimum requirements are now:

* A 64-bit-capable CPU (see

* Mac OS 10.6 or later (see



Downgrading warnings

--------------------



The 'chainstate' for this release is not always compatible with previous

releases, so if you run 0.9 and then decide to switch back to a

0.8.x release you might get a blockchain validation error when starting the

old release (due to 'pruned outputs' being omitted from the index of

unspent transaction outputs).



Running the old release with the -reindex option will rebuild the chainstate

data structures and correct the problem.



Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan

the blockchain for missing spent coins, which will take a long time (tens

of minutes on a typical machine).



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)



Transaction malleability-related fixes

--------------------------------------



This release contains a few fixes for transaction ID (TXID) malleability

issues:



- -nospendzeroconfchange command-line option, to avoid spending

zero-confirmation change

- IsStandard() transaction rules tightened to prevent relaying and mining of

mutated transactions

- Additional information in listtransactions/gettransaction output to

report wallet transactions that conflict with each other because

they spend the same outputs.

- Bug fixes to the getbalance/listaccounts RPC commands, which would report

incorrect balances for double-spent (or mutated) transactions.

- New option: -zapwallettxes to rebuild the wallet's transaction information



Transaction Fees

----------------



This release drops the default fee required to relay transactions across the

network and for miners to consider the transaction in their blocks to

0.01mBTC per kilobyte.



Note that getting a transaction relayed across the network does NOT guarantee

that the transaction will be accepted by a miner; by default, miners fill

their blocks with 50 kilobytes of high-priority transactions, and then with

700 kilobytes of the highest-fee-per-kilobyte transactions.



The minimum relay/mining fee-per-kilobyte may be changed with the

minrelaytxfee option. Note that previous releases incorrectly used

the mintxfee setting to determine which low-priority transactions should

be considered for inclusion in blocks.



The wallet code still uses a default fee for low-priority transactions of

0.1mBTC per kilobyte. 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.
