This is a new minor version release, bringing mostly bug fixes and

some minor improvements.

Upgrading and downgrading
|
||||
==========================
|
||||
|
||||
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).
|
||||
shut down (which might take a few minutes for older versions), 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
|
||||
releases, so if you run 0.9.x 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).
|
||||
|
|
@ -59,339 +40,159 @@ 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
|
||||
---------------------------
|
||||
Important changes
|
||||
==================
|
||||
|
||||
To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we
|
||||
have renamed the reference client to Bitcoin Core.
|
||||
Gitian OSX build
|
||||
-----------------
|
||||
|
||||
Autotools build system
|
||||
-----------------------
|
||||
The deterministic build system that was already used for Windows and Linux
|
||||
builds is now used for OSX as well. Although the resulting executables have
|
||||
been tested quite a bit, there could be possible regressions. Be sure to report
|
||||
these on the Github bug tracker mentioned above.
|
||||
|
||||
For 0.9.0 we switched to an autotools-based build system instead of individual
|
||||
(q)makefiles.
|
||||
Compatibility of Linux build
|
||||
-----------------------------
|
||||
|
||||
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.
|
||||
For Linux we now build against Qt 4.6, and filter the symbols for libstdc++ and glibc.
|
||||
This brings back compatibility with
|
||||
|
||||
Be sure to check doc/build-*.md for your platform before building from source.
|
||||
- Debian 6+ / Tails
|
||||
- Ubuntu 10.04
|
||||
- CentOS 6.5
|
||||
|
||||
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:
|
||||
|
||||
- -spendzeroconfchange=0 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.
