# November 17, 2023 — Issuer detection and new metrics

- We implemented **issuer detection** for Visa, Mastercard, and Elo cards. We will soon make the feature available for the remaining card networks.
- You can view the issuer in the details of each record on the **Explore payments** and **Explore transactions** screens.
- New grouping options on the **Explore** screen: you can now also group by merchant (payments and transactions), connector ID (transactions), and issuer (transactions).
- Improvements in the consolidation of metrics and alerts during volume spikes.

New **Metrics**:

- Approval rate by connector ID, card network, and issuer
- Count by merchant and risk recommendation
