Breaking Changes

●Issue #1

The 'Prisma.validator' utility has been removed from the new 'prisma-client' generator. Use the native TypeScript 'satisfies' keyword instead.

Migration Steps

  1. 1
    To opt-into the Rust-free ORM: Update the generator block in your schema with 'engineType = "client"' and 'provider = "prisma-client"'.
  2. 2
    Remove 'queryCompiler', 'driverAdapter' feature flags, and 'binaryTargets' from the Prisma schema if previously used.
  3. 3
    Install the appropriate driver adapter for your database (e.g., 'npm install @prisma/adapter-pg').
  4. 4
    Update PrismaClient instantiation to pass the driver adapter instance (e.g., 'new PrismaClient({ adapter })').
  5. 5
    For PostgreSQL extensions: Stop using the 'postgresqlExtensions' preview feature and switch to manual SQL migrations using 'prisma migrate dev --create-only'.

Release Summary

Prisma 6.16.0 marks the General Availability of the Rust-free ORM architecture and the new ESM-first 'prisma-client' generator, significantly reducing bundle sizes and improving type-checking performance.
