+
+[Bitcoin Core version 0.14.2 is now available](https://bitcoin.org/en/download).
+
+This is a new minor version release, including various bugfixes and
+performance improvements, as well as updated translations.
+
+Please report bugs using the [issue tracker on GitHub](https://github.com/bitcoin/bitcoin/issues).
+
+[Subscribe here](https://bitcoincore.org/en/list/announcements/join/) to receive
+security and update notifications.
+
+## Compatibility
+
+Bitcoin Core is extensively tested on multiple operating systems using
+the Linux kernel, macOS 10.8+, and Windows Vista and later.
+
+Microsoft ended support for Windows XP on [April 8th,
+2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+No attempt is made to prevent installing or running the software on Windows XP,
+you can still do so at your own risk but be aware that there are known
+instabilities and issues. Please do not report issues about Windows XP to the
+[issue tracker](https://github.com/bitcoin/bitcoin/issues).
+
+Bitcoin Core should also work on most other Unix-like systems but is not
+frequently tested on them.
+
+## Notable changes
+
+### miniupnp CVE-2017-8798
+
+Bundled miniupnpc was updated to 2.0.20170509. This fixes an integer signedness error
+(present in MiniUPnPc v1.4.20101221 through v2.0) that allows remote attackers
+(within the LAN) to cause a denial of service or possibly have unspecified
+other impact.
+
+This only affects users that have explicitly enabled UPnP through the GUI
+setting or through the `-upnp` option, as since the last UPnP vulnerability
+(in Bitcoin Core 0.10.3) it has been disabled by default.
+
+If you use this option, it is recommended to upgrade to this version as soon as
+possible.
+
+## Known Bugs
+
+Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin
+control and smart fee estimation does not reflect any change in target from the
+smart fee slider. It will only present an approximate fee calculated using the
+default target. The fee calculated using the correct target is still applied to
+the transaction and shown in the final send confirmation dialog.
+
