Only items listed in 740.17(b)(2) and (b)(3) require a classification. For those items, a new classification is required when the cryptographic functionality changes or other technical characteristics affecting license exception ENC eligibility – e.g., encrypted throughput. New classifications are not required for other changes, including patches, upgrades or releases, name changes. Items described in 740.17(b)(1) do not require a classification to be eligible for ENC.
