hi team, would appreciate your eyes on this proposal. @quartzmo / @bormanp / @noahdietz :) |

Can we release lock after the if below?

Not like that. Drop defer, it's not needed after the if.

Ah yes! This wasn't supposed to be here. Removed it.
remove redundant function (dead code) and place the `sync.Mutex` lock after the `if` condition

any news? this feature is so required today |

This adds support for generating UUID Version 8 as defined in RFC 9562. UUIDv8 is designed for custom or experimental use cases, allowing you to embed application-specific data while adhering to standard version and variant bits.
What’s included:
NewV8(): Generates a UUIDv8 with random values.NewV8FromReader(customA, customB, r): Allows custom values forcustom_a(48 bits) andcustom_b(12 bits) whilecustom_cfield (62 bits) is filled using a random source or secure fallback.NewV8TimeBased(r): A time-based variant ofUUIDv8that uses the current timestamp forcustom_a. It also includes a sequence number to ensure uniqueness when multiple UUIDs are generated in the same nanosecond.This addition completes support for all UUID versions in RFC 9562. Looking forward for your feedback, team!
