Bitcoin Core version 0.9.0 is now available from:
|
|
|
|
https://bitcoin.org/bin/0.9.0/
|
|
|
|
This is a new major version release, bringing 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 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 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.
|
|
|
|
|
|
OP_RETURN and data in the block chain
|
|
-------------------------------------
|
|
On OP_RETURN: There was been some confusion and misunderstanding in
|
|
the community, regarding the OP_RETURN feature in 0.9 and data in the
|
|
blockchain. 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. 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.
|
|
|
