+Bitcoin-Qt version 0.8.0 is 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:
+  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), 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)
