We have some fresh enhancements to Connectors now in preview! These primarily build on the “batching” feature for solving N+1 issues—check out [Lenny’s post](https://community.apollographql.com/t/preview-connectors-n-1-batch-support/8806) for much more detail on that!

These additions are available starting with GraphOS Router `2.2.0-rc.0` and composition `2.11.0-preview.1`.

## Highlights

1. Expressions in your `@connect` URLs are available in more places now
2. New `path` and `queryParams` values can be added to _both_ `@source` and `@connect` for more dynamic URLs. The `queryParams` feature allows you to create parameters like `?id=1&id=2&id=3`—super useful for batching!
3. A new `batch.maxSize` setting in `@connect` lets you configure how many IDs to stick in a single `$batch` request.

There’s [a new docs page](https://www.apollographql.com/docs/graphos/schema-design/connectors/preview-features) describing _all_ the current preview features and how to opt in to them. Check it out and let us know what you think!
