Summary
This release introduces experimental local explorer endpoints for DO namespaces and objects, fixes a bug preventing AI Search bindings from working in local development, and improves Miniflare's cache directory detection for better package manager compatibility.
Migration Steps
- If you rely on Miniflare's cache location and need to explicitly set it, use the new MINIFLARE_CACHE_DIR environment variable.
✨ New Features
- Local explorer now includes endpoints to list Durable Object (DO) namespaces and objects (experimental feature).
- Miniflare now supports the MINIFLARE_CACHE_DIR environment variable for specifying the cache directory.
- Miniflare now intelligently detects the cache directory location based on environment variables or standard locations, improving compatibility with modern package managers like Yarn PnP and pnpm.
🐛 Bug Fixes
- Fixed an issue where AI Search bindings would fail during local development (`wrangler dev`) with an error indicating a non-serializable type in the RPC stub.
