+  Bitcoin Core 0.16.3 is now available with a fix for a
+  denial-of-service vulnerability affecting earlier versions of Bitcoin
+  Core.
+---
+Bitcoin Core version 0.16.3 is now available for [download][download
+page] with a fix for a denial-of-service vulnerability introduced in
+Bitcoin Core 0.14.0 and affecting all subsequent versions though to
+0.16.2.  We highly recommend users of all affected versions immediately
+upgrade to 0.16.3.
+
+Security issue: it was discovered that older versions of Bitcoin Core
+will crash if they try to process a block containing a transaction that
+attempts to spend the same input twice.  Such blocks are invalid, so
+they can only be created by a miner willing to sacrifice their allowed
+income for creating a block of at least 12.5 BTC (about $80,000 USD as
+of this writing).  This release eliminates the crash, allowing the
+software to quietly reject such invalid blocks.
+
+For a complete list of changes, please see the [release notes][].  If
+have any questions, please stop by our [IRC chatroom][irc] and we’ll do
+our best to help you.

+Bitcoin Core version 0.16.3 is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-0.16.3/>
+
+This is a new minor version release, with various bugfixes
+as well as updated translations.
+
+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 version 0.15.0 or newer, your chainstate database will be converted to a
+new format, which will take anywhere from a few minutes to half an hour,
+depending on the speed of your machine.
+
+Note that the block database format also changed in version 0.8.0 and there is no
+automatic upgrade code from before version 0.8 to version 0.15.0 or higher. Upgrading
+directly from 0.7.x and earlier without re-downloading the blockchain is not supported.
+However, as usual, old wallet versions are still supported.
+
+Downgrading warning
+-------------------
+
+Wallets created in 0.16 and later are not compatible with versions prior to 0.16
+and will not work if you try to use newly created wallets in older versions. Existing
+wallets that were created with older versions are not affected by this.
+
+Compatibility
+==============
+
+Bitcoin Core is extensively tested on multiple operating systems using
+the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.
+
+Bitcoin Core should also work on most other Unix-like systems but is not
+frequently tested on them.
+
+Notable changes
+===============
+
+Denial-of-Service vulnerability
+-------------------------------
+
+A denial-of-service vulnerability exploitable by miners has been discovered in
+Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of
+the vulnerable versions to 0.16.3 as soon as possible.
