Due to the vulnerability in discovered in OpenSSL we are releasing updated clients built with the latest version of OpenSSL which is patched against the 'Heartbleed' flaw. You are only vulnerable if you use the rpcssl option from the command line option. Bitcoin GUI users of the payment request feature on 0.9 were exposed to this vulnerability but this does not apply to us as this feature is disabled in our release.
In addition to this fix, Mac now has QR code support and shows the version clearly in the about window.
Download the updated 0.8.6.2 client from the Official Hirocoin Download page.
