+**`(fix):`** Propagate `explode` field from OpenAPI query parameters through the old importer pipeline

+## 4.60.2
+**`(fix):`** Fix `explode: false` query parameter serialization for array types. When an OpenAPI spec
+sets `explode: false` on an array query parameter, the generated SDK now serializes values
+as comma-separated strings (e.g. `tags=A,B,C`) instead of repeated keys (e.g. `tags=A&tags=B&tags=C`).

 Remove generator-cli from Docker image since it is now bundled via esbuild.

+## 3.52.0
+**`(feat):`** Enable `generateSubpackageExports` by default. Generated TypeScript SDKs now include
+subpackage export entries in `package.json`, allowing users to import subpackage clients
+directly (e.g., `import { FooClient } from '@acme/sdk/foo'`). This enables JavaScript
+bundlers to tree-shake unused subpackages, resulting in smaller bundle sizes.
+To opt out, explicitly set `generateSubpackageExports: false` in your generator config.

+significantly smaller webpack bundle than importing the full SDK.
