**Product Changes**

[New “Color” variable data type allows you to dynamically update colors](http://support.tulip.co/en/articles/3639705-how-to-dynamically-change-colors-of-widgets)

- You can now update and store colors every time an operator uses an app.

[New “Print” functionality allows you to print out live app data or save it in a local PDF](http://support.tulip.co/en/articles/3648057-how-operators-can-print-app-data-or-save-it-to-a-pdf)

- When an operator completes an app, they can now print a formatted step with all the relevant values from their most recent operation

[Use RFID as an event in the App Builder rather than login method](https://support.tulip.co/en/articles/2272092-list-of-plug-and-play-devices-that-work-with-tulip)

- You can now choose whether to use an RFID scanner as a login method OR as a device within an app. Reach out to [support@tulip.co](mailto:support@tulip.co) if you would like to use RFID scanner events within an app.

[Renamed “Date Ranges” to “Current Hour” and “Current Week”](http://support.tulip.co/en/articles/3566590-understanding-date-ranges)

- We replaced some confusing wording in the Analytics Builder with the “Current Hour” and “Current Week” date ranges

- You can now both send and receive datetime data via SQL and HTTP connectors

[Combine “Interval” data with “datetime” data in the Expression Editor](https://support.tulip.co/en/articles/3551940-compare-two-timestamps-in-apps)

- Improvement 1: Intervals are now always expressed in seconds across Analytics Builder and Trigger Editor
- Improvement 2: Adding a number or integer to an interval returns an interval
- Improvement 3: Adding/subtracting interval from datetime data now returns a datetime data type

[New “Dropdown” widget on normal Steps](https://support.tulip.co/en/articles/3591243-adding-input-widgets-to-normal-steps)
