Highlights

ORM

Features

Prisma Client

• Added a queryPlanCacheMaxSize option to the PrismaClient constructor for fine-grained control over the query plan cache. Pass 0 to disable the cache entirely, or omit it to use the default cache size. A larger value can improve performance in applications that execute many unique queries, while a smaller one can reduce memory usage. (#29503)

Bug Fixes

Prisma Client

• Fixed an equality filter panic and incorrect ::jsonb cast when filtering on PostgreSQL JSON list columns. Queries using where: { jsonListField: { equals: [...] } } no longer panic with a type mismatch or emit invalid SQL. (prisma/prisma-engines#5804)
• Fixed case-insensitive JSON field filtering (mode: insensitive), allowing where: { jsonField: { equals: "...", mode: "insensitive" } } to work correctly. (prisma/prisma-engines#5806)
• Fixed incorrect parameterization of enum values that have a custom database name set via @map. (#29422)
• Fixed a database parameter limit check (P2029), which could incorrectly reject or miss over-limit queries. (#29422)
• Fixed a regression that caused missing SQL Server VARCHAR casts for parameterized values. (prisma/prisma-engines#5801)

Schema Engine

• Fixed a misleading error message in prisma migrate diff that referenced the --shadow-database-url CLI flag, which was removed in Prisma 7. (#29455)
• Fixed prisma migrate dev (and shadow database migration replay in general) failing with CREATE INDEX CONCURRENTLY cannot run inside a transaction block when a migration contained concurrent index creation statements on PostgreSQL. (prisma/prisma-engines#5799)
• Fixed PostgreSQL introspection silently dropping sequence defaults when the database returns the schema-qualified form pg_catalog.nextval('sequence_name'::regclass) instead of the bare nextval(...). Columns backed by sequences now correctly appear as @default(autoincrement()) in the Prisma schema in all cases. (prisma/prisma-engines#5802)

Driver Adapters

• @prisma/adapter-d1: Savepoint operations (createSavepoint, rollbackToSavepoint, releaseSavepoint) now silently no-op with debug logging instead of executing SQL statements, consistent with how the D1 adapter already treats top-level transactions. (#29499)
