## Highlights
### Native support for UUIDv7
Previous to this release, the Prisma Schema function `uuid()` did not accept any arguments and created a UUIDv4 ID. While sufficient in many cases, UUIDv4 has a few drawbacks, namely that it is not temporally sortable.
UUIDv7 attempts to resolve this issue, making it easy to temporally sort your database rows by ID!
To support this, weโve updated the `uuid()` function in Prisma Schema to accept an optional, integer argument. Right now, the only valid values are `4` and `7`, with `4` being the default.
```tsx
model User {
id String @id @default(uuid()) // defaults to 4
name String
}
model User {
id String @id @default(uuid(4)) // same as above, but explicit
name String
}
model User {
id String @id @default(uuid(7)) // will use UUIDv7 instead of UUIDv4
name String
}
```
