Summary
This release moves several experimental and unstable exports to dedicated utility packages or removes them entirely, improving stability and modularity. Bug fixes address issues related to configuration resolution, error handling during development, and local Workflows data serialization.
Migration Steps
- If you were importing `unstable_getWorkerNameFromProject` from `wrangler`, update your import to use `getWorkerNameFromProject` from `@cloudflare/workers-utils`.
- If you were using experimental autoconfig exports, migrate to using the `@cloudflare/autoconfig` package directly (without the `experimental_` prefixes).
🐛 Bug Fixes
- Relative `cf-worker` entrypoint imports in `cloudflare.config.ts` are now resolved relative to the importing module, fixing incorrect resolution when the import is in a nested file.
- Prevented `wrangler dev` from crashing when source-mapping truncated error chunks by catching source map library errors and returning un-source-mapped text.
- Fixed `Uint8Array` step outputs in local Workflows being persisted with the full backing `ArrayBuffer`, which caused `SQLITE_TOOBIG` errors; views are now copied to a tight buffer before persistence.

⚡ Deprecations
