🔧 Bug Fixes & Patches (2)
- In Prisma ORM 6.16.0, we've enabled usage of the new `engineType = client` with Prisma Postgres, but our validation rules permitted invalid combinations of Prisma Postgres URLs and driver adapters. This now produces a clear error message indicating Prisma Postgres URLs and driver adapters are mutually exclusive.
- In the previous minor release, we've included a change that calls `unref()` on NodeJS timers to prevent them from keeping the NodeJS event loop active. This change unintentionally affected non-NodeJS runtimes like `workerd`, where it has resulted in runtime errors. This behavior has been made conditional to prevent these runtime errors.
