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
,
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.

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.
