## Executive Summary (TL;DR)
Prisma 7.8.0. Source highlight: Today, we are excited to share the `7.8.0` stable release 🎉

## New Features
- 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
- 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)
- Fixed a misleading error message in `prisma migrate diff` that referenced the `--shadow-database-url` CLI flag, which was removed in Prisma 7. (#29455)
