SHA-3 is very different from SHA-2 in design," says NIST’s Shu-jen Chang. "It doesn’t replace SHA-2, which has not shown any problem, but offers a backup. It takes years to develop a new standard, and we wanted to be prepared in case problems do occur.
SHA-3 took 9 years to develop.

SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions
The SHA-3 family defined in FIPS 202 consists of four cryptographic hash functions based on an instance of KECCAK, called SHA3-224, SHA3-256, SHA3-384, and SHA3-512, and two extendable-output functions (XOFs), called SHAKE128 and SHAKE256.
The previous standard FIPS 180-4 defined the SHA-2 suite and SHA-1, the latter which now is considered obsolete and being phased out.
FIPS 180-4 has also been updated:
