Bitcoin Core version 0.9.0 is now available from:

  https://bitcoin.org/bin/0.9.0/

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 al=
l
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 http://support.apple.com/kb/ht3696);
* Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

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 chainstat=
e
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 an=
d
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 =3D 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 =3D now + 1000
    > walletpassphrase 10
    walletunlocktime =3D 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 o=
f
  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 informatio=
n

Transaction Fees
----------------

This release drops the default fee required to relay transactions across th=
e
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.

0.9.0 Release notes
