## For the release team

The `relnote` tool, at `golang.org/x/build/cmd/relnote`, operates on the files
in `doc/next`.

As a release cycle nears completion, run `relnote todo` to get a list of
unfinished release note work.

// The SHAKE functions are recommended for most new uses. They can produce
// output of arbitrary length. SHAKE256, with an output length of at least
// 64 bytes, provides 256-bit security against all attacks.  The Keccak team
// recommends it for most applications upgrading from SHA2-512. (NIST chose a
// much stronger, but much slower, sponge instance for SHA3-512.)
//
// The SHA-3 functions are "drop-in" replacements for the SHA-2 functions.
