From Andrey Pechkurov:

Adds an optional randomness pool mode for Random (Version 4) UUID generation. The pool contains random bytes read from the random number generator on demand in batches. Enabling the pool may improve the UUID generation throughput significantly.

Since the pool is stored on the Go heap, this feature may be a bad fit for security sensitive applications. That's why it's implemented as an opt-in feature.

From Samuel Roth:

Added support for NullUUID

A NullUUID can be marked not valid (i.e., null) for use with JSON and the database/sql/driver.Scanner interfaces.

This release introduces the NewString() function which is the equivalent of uuid.New().String().

There are no code changes. A missing period was add to a godoc comment and the linter was told to not complain that the results of hash.Write() are ignored (the function cannot fail)

Do not allocate memory for errors (it is only one word)

Optimize length of time it takes to discover an input is bad by no longer using fmt.Errorf, which is quite slow. It now uses a custom error type that formats the string when the Error method is called rather than when generating the error.

This release contains

• Allow concurrent, re-creatable usage #44 by trabetti was merged on Apr 16, 2019
• Fix race in NewUUID() #64 by AstolfoKawaii was merged on Jul 2, 2020
• Minor formatting and typo fixes

Actually include darkfeline's fixes when no interfaces are found.

This release includes the MustParse as well as parsing of

Microsoft encoding {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
Raw hex encoding: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

This is the same as 1.0.0, but simply as the v in front.

Finally marked this API as stable and release v1.
There were no code changes as part of this release.

This release includes a fix to the broken json.go file (now removed).

Initial checkin after converting from byte slices to arrays.
