This is the GitHub repo for the IETF draft surrounding the topic of new UUID formats. Various discussion will need to occur to arrive at a standard and this repo will be used to collect and organize that information.
UUID version 6: A re-ordering of UUID version 1 so it is sortable as an opaque sequence of bytes. Easy to implement given an existing UUIDv1 implementation.
time_high|time_mid|time_low_and_version|clk_seq_hi_res|clk_seq_low|node
UUID version 7: An entirely new time-based UUID bit layout sourced from the widely implemented and well known Unix Epoch timestamp source.
unix_ts_ms|ver|rand_a|var|rand_b
UUID version 8: A free-form UUID format which has no explicit requirements except maintaining backward compatibility.
custom_a|ver|custom_b|var|custom_c
Max UUID: A specialized UUID which is the inverse of the Nil UUID from RFC4122.
FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
