### Fixes & improvements

- API: Added a `pooler_enabled` property to the [project update API call](https://api-docs.neon.tech/reference/updateproject) to indicate whether or not connection pooling is enabled.
- API: Fixed several bugs that could cause intermittent 409 responses, which indicate a request conflict with the current state of the target resource.
- Control Plane: Implemented connection pooling support for Neon projects, allowing Neon to support a greater number of connections. For information about enabling connection pooling for a Neon project, see [Connection pooling](/docs/connect/connection-pooling/).
