[security] Go 1.5.4 and Go 1.6.1 pre-announcement

[Andrew Gerrand]

We plan to issue Go 1.5.4 and Go 1.6,1 on Wednesday April 13 at approximately 2am UTC.

These are minor releases to fix two security issues.

Following our policy at https://golang.org/security, this is the pre-announcement of those releases.

They will be followed by a more significant 1.6.2 point release that will fix a number of issues.

Cheers,

Andrew, on behalf of the Go team
