# Prisma ORM 7.3.0: Faster Query Compilation, Safer BigInt JSON, Better Adapters

**[Prisma Blog](https://daily.dev/sources/prisma-blog)** · 3 min read · 0 upvotes · 0 comments

## Summary

Prisma ORM 7.3.0 ships several performance and reliability improvements. A new `compilerBuild` option lets developers choose between `fast` (default, larger footprint) and `small` (optimized for bundle size) query compiler builds. Raw queries via `$executeRaw` and `$queryRaw` now bypass the compiler path entirely, reducing latency. The MSSQL adapter is updated to v12.2.0, and the `better-sqlite3` adapter pins a fixed SQLite dependency to avoid a 3.51.0 regression. The mapped enum behavior introduced in 7.0 is reverted for better compatibility with Prisma 6 migrations. BigInt fields in `relationJoins` JSON aggregation are now cast to text to prevent silent precision loss in JavaScript.
