 Changes to be included in the next upcoming release
 
 - Added a default .gitignore that ignores node_modules in the connector template ([#34](https://github.com/hasura/ndc-nodejs-lambda/pull/34))
+- Updated to NDC TypeScript SDK to v5.0.0 ([#35](https://github.com/hasura/ndc-nodejs-lambda/pull/35))
+  - The BigInt scalar type now uses the biginteger type representation
 
 ## [1.4.0] - 2024-05-08
 - Removed type inference recursion limit ([#33](https://github.com/hasura/ndc-nodejs-lambda/pull/33)). This enables the use of very nested object graphs.
