Version 3.3 (Wed Oct 14 2020)
- [BUILD] Allow overriding build settings from the environment.
- [COMPATIBILITY] Document how the UUID fields are interpreted.
- [PORTABILITY] Don't use memcpy on /dev/mem on arm64.
- [PORTABILITY] Only scan /dev/mem for entry point on x86.
- Support for SMBIOS 3.3.0. This includes new processor names, new port
connector types, and new memory device form factors, types and
technologies.
- Add bios-revision, firmware-revision and system-sku-number to -s option.
- Use the most appropriate unit for cache size.
- Decode system slot base bus width and peers.
- Important bug fixes:
Fix Redfish Hostname print length
Fix formatting of TPM table output
Fix System Slot Information for PCIe SSD
Don't choke on invalid processor voltage
- Use the most appropriate unit for cache size.
Version 3.2 (Wed Sep 14 2018)
- [COMPATIBILITY] The UUID is now displayed using lowercase letters, per
RFC 4122 (#53569). You must ensure that any code parsing it is

.SH UUID FORMAT
There is some ambiguity about how to interpret the UUID fields prior to SMBIOS
specification version 2.6. There was no mention of byte swapping, and RFC 4122
says that no byte swapping should be applied by default. However, SMBIOS
specification version 2.6 (and later) explicitly states that the first 3 fields
of the UUID should be read as little-endian numbers (byte-swapped).
Furthermore, it implies that the same was already true for older versions of
the specification, even though it was not mentioned. In practice, many hardware
vendors were not byte-swapping the UUID. So, in order to preserve
compatibility, it was decided to interpret the UUID fields according to RFC
4122 (no byte swapping) when the SMBIOS version is older than 2.6, and to
interpret the first 3 fields as little-endian (byte-swapped) when the SMBIOS
version is 2.6 or later. The Linux kernel follows the same logic.
