Java version 8u66 now available, with critical security fixes

Oracle has released Java version 8u66, full version string 1.8.0_66-b17 (note that the ‘b’ means ‘build’, not beta!).

Although the regular bug fixes in this release seem fairly unimportant, the security fixes are more significant. Of the 25 new security fixes, 23 of the vulnerabilities may be exploited over a network without the need for any authentication, and 7 carry the maximum risk score. You are therefore strongly recommended to update at the earliest opportunity, from here.
