+### Automatic seeding during migrations has been removed
+
+In Prisma ORM v6 and earlier, running `prisma migrate dev` or `prisma migrate reset` would automatically execute your seed script after applying migrations. This automatic seeding behavior has been removed in Prisma ORM v7.
+
+To seed your database in v7, you must explicitly run:
+
+```terminal
+npx prisma db seed
+```
+
 ### Various environment variables have been removed
 
 We've removed a small selection of Prisma-specific environment variables.
