[09-21-2020]

The first release of the FIPS 140-3 Implementation Guidance document was published on September 21, 2020. This release incorporates 41 IGs, down from the 104 IGs currently in FIPS 140-2 IG document. Many of the IGs were no longer required as they were incorporated into ISO/IEC 19790, ISO/IEC 24759, and the SP 800-140x documents. Many thanks to those who helped identify, draft, review, and publish this new CMVP document.
