Windows XP was released in October 2001 and has been one of Microsoft’s most successful operating systems.
Since then, Windows Vista, Windows 7, Windows 8, Windows 8.1 and very soon Windows 10 have all come along. In April 2009 Microsoft ended mainstream support and in April 2014 ended extended support, meaning that no security updates have been released. At the time of writing, since April 2014, Microsoft have released fixes across Windows, Internet Explorer and the .NET Framework for 29 vulnerabilities of critical severity and 57 of important severity. It is likely that the majority of these vulnerabilities exist in Windows XP and remain unpatched.

XJTAG will therefore not be supporting Windows XP from the 3.4.0 release onwards. We recognise that some customers still have XP deployments, particularly in production. To support them, we will maintain the 3.3 branch of XJTAG releases for an extended period offering updates as and when they’re needed to allow customers to continue to work, but not back-porting new features. This period of extended support will end in September 2016.
