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

Denial-of-Service vulnerability CVE-2018-17144

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 0.14.3, 0.15.2 or 0.16.3 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.
