# Changelog: July 2022

![July 2022 changelog](https://blog.basistheory.com/hubfs/Imported_Blog_Media/62ed14bdeb86d316568a3384_Changelog_%20%20July%202022.jpg)

## The Highlights

### Token expiration

Whether mandated by PCI or by your organization's internal data retention policies, developers need the ability to purge data automatically. To help, we built the new [“expires\_at” property](https://developers.basistheory.com/docs/api/tokens/#token-expiration). The enhancement purges the data automatically from the Basis Theory system at a set expires\_at date and time.

### Overwrite “card” and “bank” Token Type properties

[Token Types](https://developers.basistheory.com/docs/api/tokens/token-types) are templates with pre-configure properties for some of the most popular types of sensitive data and their use cases. With the new enhancements to card and bank tokens, developers can now modify these templates to configure their [Fingerprints](https://developers.basistheory.com/docs/concepts/what-are-tokens#fingerprinting), [Search Indexes](https://developers.basistheory.com/docs/concepts/what-are-tokens#search-indexes), [Mask](https://developers.basistheory.com/docs/concepts/what-are-tokens#masking), and [Alias](https://developers.basistheory.com/docs/concepts/what-are-tokens#aliasing) properties using [expressions](https://developers.basistheory.com/docs/expressions#introduction).

For example, the default mask value for the card Token Type defaults to revealing all but the last 4 of a card number. While this is great for validating a credit card, it’s less helpful if you’re trying to validate the card’s [Bank Identification Number (BIN)](https://blog.basistheory.com/what-is-bank-identification-number)—or the *first* six numbers of a credit card. With the changes, developers now only need to change the mask’s default expression from "mask":  to "mask":  to reveal the card’s BIN.
