Here at Blues the Notehub team has been busy, and today I want to share some of the improvements that we’ve shipped over the last month or two. All of these features are live and available for you to use in your projects today. ## JSONata Improvements [JSONata](https://dev.blues.io/guides-and-tutorials/notecard-guides/using-jsonata-to-transform-json.md) is a JSON query and transform language that you can use as part of [Notehub routes](https://dev.blues.io/notehub/notehub-walkthrough.md#routing-data-with-notehub). We’ve recently implemented a number of features to make it easier to work with JSONata in Notehub. To start, we’ve improved our JSONata editor to recognize JSONata syntax, and give you visual feedback if you make any mistakes. ![A JSONata error in Notehub’s route editor](https://dev.blues.io/images/blog/posts/whats-new-in-notehub/jsonata-error.png?v=78fbfe43) Next, if any JSONata errors occur during routing, Notehub now displays the error in the event’s route log for easier debugging. ![A route log showing a routing error](https://dev.blues.io/images/blog/posts/whats-new-in-notehub/route-log.png?v=e3dc966e) And finally, Notehub now allows you to provide JSONata for proxy routes used during [web transactions](https://dev.blues.io/notecard/notecard-walkthrough/web-transactions.md). Specifically, for proxy routes you can now provide JSONata expressions both for outbound *and* inbound requests. Outbound expressions are applied before Notehub invokes the external service, and inbound expressions are applied before Notehub sends data back to your device. ![JSONata used in a Notehub proxy route](https://dev.blues.io/images/blog/posts/whats-new-in-notehub/proxy-jsonata.png?v=7a534756) The following short video shows off the new JSONata features in action, and is worth watching if you want to see all you can do with JSONata in Notehub.

All Notehub projects have a new Export button that allows you to filter your data, choose the fields you wish to include, choose an export format (JSON or CSV), and ultimately download a file with your data. ![The export button in a Notehub project](https://dev.blues.io/images/blog/posts/whats-new-in-notehub/export-button.png?v=08423906) You can learn more about [exporting data in our docs](https://dev.blues.io/notehub/notehub-walkthrough.md#exporting-data). And one more cool thing: you can do this same exporting through the [Notehub Event API](https://dev.blues.io/guides-and-tutorials/using-the-notehub-api.md) with the new `format` and `selectFields` arguments. ## Session Changes Next, we’ve made some changes to how sessions work within Notehub. Previously, Notehub would only create a `_session.qo` event when a [Session](https://dev.blues.io/api-reference/glossary.md#session) started. Now, Notehub creates `_session.qo` events each time a Session between a Notecard and Notehub begins and ends—and each event has been enhanced with [a number of new metadata fields](https://dev.blues.io/api-reference/system-notefiles.md#session-qo) you may find useful. For example, the session start event now includes the RAT (Radio Access Technology) being used, and the `ssid` if the connection was made over WiFi. The session end event now includes metadata about the completed session, including how many Notes were received, how many Notes were routed, and how many bytes were used. The following video walks through both the new data exporting, as well as the Notehub session changes.

New in Notehub is a Blynk route that allows you connect your devices and start building web and mobile dashboards in Blynk. ![A dashboard in Blynk](https://dev.blues.io/images/guides/route-tutorial/blynk/blynk-dashboard.png?v=72f70786) Complete our [Blynk Routing Tutorial](https://dev.blues.io/guides-and-tutorials/routing-data-to-cloud/blynk.md) to try it out. And check out the following video to see the Blynk integration in action.
