This release introduces support for UUIDs version 6 to 15. It also extends uuid to allow specifying a single version or a set of versions.

Continue reading to explore the detailed updates it brings.

New version constraint for uuid​

Until now, generating UUIDs for a given version has been the responsibility of the arbitrary uuidV. With version 3.21.0, we added support for custom versions directly within uuid and deprecated uuidV.

To switch from the deprecated uuidV to the new uuid syntax, you should make the following change:

--- fc.uuidV(4)
+++ fc.uuid({ version: 4 })

Starting with 3.21.0, uuid allows generating multiple versions. For instance, if users want to generate both UUID v4 and v7, they can use:

fc.uuid({ version: [4, 7] });

Changelog since 3.20.0​

The version 3.21.0 is based on version 3.20.0.
