BTCPay Server 1.6.1 release fixes critical altcoins integration issue also affecting XMR merchants

The new BTCPay Server1 v1.6.12 release fixes a critical bug which affects altcoins integration, including XMR-accepting merchants:

This fix a critical issue introduced by 1.6.0. If you are using altcoins integration, you need to update urgently as some change rate may be inverted for some pairs.

Bug fixes

- Fix stack overflow if ripio rate provider is unavailable @NicolasDorier
- Fix: For some asset pair the kraken rate was inverted (#3957) @NicolasDorier

The bug was initially reported3 by Sethforprivacy4 and the patched version was released by NicolasDorier5.

Users that are currently still on v1.6.0 and use altcoins should update as soon as possible to avoid customers paying with the wrong exchange rate.
