In May 2026, delivered Prisma Editor Enhancements in prisma/language-tools with a focus on performance, DX, and language capabilities. Implemented an opt-out mechanism for the PSL language server via the // use prisma-next directive, enabling users to disable diagnostics and language features for Prisma Next files. Introduced lazy language-server startup to defer initialization until needed, reducing idle CPU and memory usage. Added syntax highlighting for prisma-next types and namespace blocks to preserve readability and align with new language constructs. Exposed explicit exports for @prisma/language-server/prisma-next to isolate the prisma-next surface and prevent unnecessary bundling of the full server. Added integration tests to guarantee prisma-next files produce zero diagnostics while regular files continue to receive diagnostics.

October 2024 performance summary for prisma-engines: Modernized the Dependency and Metrics API by upgrading core crates and adjusting instrumentation, resulting in improved stability and observability. Key changes included updating mobc and metrics crates to the latest versions, replacing metric recording from macros with direct API calls, and aligning Cargo.toml to reflect the changes. These updates lay the groundwork for future crate-driven enhancements and provide a cleaner, more maintainable metrics path across the engine.
