Bitcoin Core 0.9.2 has been released and is available for download from https://bitcoin.org/bin/0.9.2/
This is minor release version containing mostly bug fixes and a few improvements to the code base and GUI.
Important: Users should upgrade to this release due to critical security updates in the included OpenSSL library (CVE-2014-0224 which is a new vulnerability – not the Heartbleed Bug)
