+Bitcoin Core version 0.9.0rc1 is now available from:
 
+  http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0rc1/
+
+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 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.
+
+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 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.
+

+- Add RPC call 'decodescript' to decode a hex-encoded transaction script

+- Optimize rescan to skip blocks prior to birthday
+- Let user select wallet file with -wallet=foo.dat
+- Consider generated coins mature at 101 instead of 120 blocks
+- Improve wallet load time
+- Don't count txins for priority to encourage sweeping

+- Fix rescan to start from beginning after importprivkey
+
+Mining:

+- 'getblocktemplate' does not require a key to create a block template
+
+Protocol and network:
+
+- Send tx relay flag with version

+
+Validation:

+- Detect any sufficiently long fork and add a warning.
+- Call the -alertnotify script when we see a long or invalid fork.
+- Fix multi-block reorg transaction resurrection
+- Reject non-canonically-encoded serialization sizes
+- Only create signatures with even S, and verification mode to check.
+- Reject dust amounts during validation
+- Use 'low S' as malleability breaker rather than 'even S'
+- Skip unspendable outputs in consistency check
+- Generalize the remove-outputs check for fully-prunable transactions
+- Accept nLockTime transactions that finalize in the next block"
+
+Build system:
+
+- Switch to autotools-based build system
+- Build without wallet by passing `--disable-wallet` to configure, this
+  removes the BerkeleyDB dependency

+- Windows 64-bit build support
+- Solaris compatibility fixes
+- Check integrity of gitian input source tarballs
+- Enable full GCC Stack-smashing protection for all OSes
+
+GUI:
+

+- Add payment request (BIP 0070) support
+- Improve options dialog
+- Show transaction fee in new send confirmation dialog

+  missing, or when the -choosedatadir option is passed
+- Save and restore window positions
+- Add vout index to transaction id in transactions details dialog
+- Add network traffic graph in debug window

+- Add Coin Control Features
+- Improve receive coins workflow: make the 'Receive' tab into a form to
+  request payments, and move historical address list functionality to File menu.
+- Rebrand to `Bitcoin Core`
+- Move initialization/shutdown to a thread. This prevents "Not responding" messages during start.
+  Also show a window during shutdown.
