- Makefile: extend copyright check test to scan all files with YAML
headers
- Exclude alerts from check -- lack of a license shouldn't prevent
us from publishing emergency information
- Also add license to Makefile itself
- Fix all errors caught by new test
- For release notes, also link to github.com/bitcoin/bitcoin
repository as origin
- Also update README.md release instructions to include license

optional_title: Bitcoin-Qt version 0.8.0 released
|
|
---
|
|
Bitcoin-Qt version 0.8.0 are now available from:
|
|
<http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.0/>
|
|
|
|
This is a major release designed to improve performance and handle the
|
|
increasing volume of transactions on the network.
|
|
|
|
Please report bugs using the issue tracker at github:

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), then run the installer (on Windows) or just copy over
|
|
/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
|
|
|
|
The first time you run after the upgrade a re-indexing process will be
|
|
started that will take anywhere from 30 minutes to several hours,
|
|
depending on the speed of your machine.
|
|
|
|
Incompatible Changes
|
|
--------------------
|
|
|
|
This release no longer maintains a full index of historical transaction ids
|
|
by default, so looking up an arbitrary transaction using the getrawtransaction
|
|
RPC call will not work. If you need that functionality, you must run once
|
|
with -txindex=1 -reindex=1 to rebuild block-chain indices (see below for more
|
|
details).
|
|
|
|
Improvements
|
|
------------
|
|
|
|
Mac and Windows binaries are signed with certificates owned by the Bitcoin
|
|
Foundation, to be compatible with the new security features in OSX 10.8 and
|
|
Windows 8.
|
|
|
|
LevelDB, a fast, open-source, non-relational database from Google, is
|
|
now used to store transaction and block indices. LevelDB works much better
|
|
on machines with slow I/O and is faster in general. Berkeley DB is now only
|
|
used for the wallet.dat file (public and private wallet keys and transactions
|
|
relevant to you).
|
|
|
|
Pieter Wuille implemented many optimizations to the way transactions are
|
|
verified, so a running, synchronized node uses less working memory and does
|
|
much less I/O. He also implemented parallel signature checking, so if you
|
|
have a multi-CPU machine all CPUs will be used to verify transactions.
|
|
|
|
New Features
|
|
------------
|
|
|
|
"Bloom filter" support in the network protocol for sending only relevant transactions to
|
|
lightweight clients.
|
|
|
|
contrib/verifysfbinaries is a shell-script to verify that the binary downloads
|
|
at sourceforge have not been tampered with. If you are able, you can help make
|
|
everybody's downloads more secure by running this occasionally to check PGP
|
|
signatures against download file checksums.
|
|
|
|
contrib/spendfrom is a python-language command-line utility that demonstrates
|
|
how to use the "raw transactions" JSON-RPC api to send coins received from particular
|
|
addresses (also known as "coin control").
|
|
|
|
New/changed settings (command-line or bitcoin.conf file)
|
|
--------------------------------------------------------
|
|
|
|
dbcache : controls LevelDB memory usage.
|
|
|
|
par : controls how many threads to use to validate transactions. Defaults to the number
|
|
of CPUs on your machine, use -par=1 to limit to a single CPU.
|
|
|
|
txindex : maintains an extra index of old, spent transaction ids so they will be found
|
|
by the getrawtransaction JSON-RPC method.
|
|
|
|
reindex : rebuild block and transaction indices from the downloaded block data.
|
|
|
|
New JSON-RPC API Features
|
|
-------------------------
|
|
|
|
lockunspent / listlockunspent allow locking transaction outputs for a period of time so
|
|
they will not be spent by other processes that might be accessing the same wallet.
|
|
|
|
addnode / getaddednodeinfo methods, to connect to specific peers without restarting.
|
|
|
|
importprivkey now takes an optional boolean parameter (default true) to control whether
|
|
or not to rescan the blockchain for transactions after importing a new private key.
|
|
|
|
Important Bug Fixes
|
|
-------------------
|
|
|
|
Privacy leak: the position of the "change" output in most transactions was not being
|
|
properly randomized, making network analysis of the transaction graph to identify
|
|
users' wallets easier.
|
|
|
|
Zero-confirmation transaction vulnerability: accepting zero-confirmation transactions
|
|
(transactions that have not yet been included in a block) from somebody you do not
|
|
trust is still not recommended, because there will always be ways for attackers to
|
|
double-spend zero-confirmation transactions. However, this release includes a bug
|
|
fix that makes it a little bit more difficult for attackers to double-spend a
|
|
certain type ("lockTime in the future") of zero-confirmation transaction.
|
|
|
|
Dependency Changes
|
|
------------------
|
|
|
|
Qt 4.8.3 (compiling against older versions of Qt 4 should continue to work)
|
|
|
