Highlights

Better support for tracing in MongoDB

The tracing Preview feature now has full support for MongoDB with previously missing functionality now implemented. This is a part of the ongoing effort to stabilize this Preview feature and release it in General Availability.

tracing is a Preview feature that enables built-in support for OpenTelemetry instrumentation inside the Prisma Client and provides deep insights into the performance and timing of your queries. See our documentation for more information.

For an easy to use and zero-configuration tracing instrumentation tool with a dashboard that provides an overview of your queries, statistics, and AI-powered recommendations, try Prisma Optimize.

WebAssembly engine size decrease for edge functions

Due to recent changes, some users experienced a steep increase of the bundle size in Prisma 5.20 when using the driverAdapters Preview feature, going over the 1 MB limit on the free tier of Cloudflare Workers. This has now been fixed.

Fixes and improvements

• Avoid regex crate for wasm bundle size (to keep cloudflare free plan)
