+Drop source map resolution for service-worker scripts
+
+Stack traces from service-worker scripts (provided via `legacy.serviceWorkerScript`) are no longer source-mapped. Service-worker scripts have no associated module path, so their `//# sourceMappingURL=` comments can no longer be resolved to a source map. Module workers continue to be source-mapped via `sourcemap`-type manifest modules.

+Adopt the `@cloudflare/config` worker configuration format
+
+Workers are now configured with a `workers` array of `{ config, legacy, dev }` entries, where `config` follows the shared `@cloudflare/config` output schema (including inline module `manifest`s) rather than the previous flat per-worker options. Service bindings, tail consumers, assets, and source maps are all driven from this format:
+
+- Service bindings support the `external`, `network`, and `disk` designators alongside worker/fetcher/node-handler bindings.
+- Tail consumers accept `entrypoint` and `props`.
+- Assets expose a `hasUserWorker` flag to control router behaviour.
+- Source maps are provided inline as `sourcemap`-type manifest modules.

+Remove `SourceOptions`, `NameSourceOptions`, `ModuleDefinition`, and `ModuleDefinitionSchema` from Miniflare's public API
+
+Worker source is now provided inline through the config manifest, so stack traces are source-mapped directly against it. The `SourceOptions` intermediate representation and its associated exports are no longer needed and have been removed.
