# Exporter 1.21.0 release notes

December 17, 2024  |  **[Download](https://aerospike.com/download/oandm/prometheus/)**

## New in this version

This version implements fixes in security, authentication, and histogram data retrieval.

## Bug fixes

-   Aerospike Prometheus Exporter (APE) was sending the wrong histogram `info` command to the server if the namespace name contained a hyphen. \[OM-209\]
    
-   If APE logged in using PKI, it did not scrape the `aerospike_users_conns_in_use` metric. Scraping was unaffected if APE logged in using internal authentication. \[OM-211\]
    

## Security

-   Updated the `github.com/sirupsen/logrus` package. The affected version was vulnerable to Denial of Service (DoS) via the `logrus.Writer()` function, which could be triggered by logging text longer than 64kb without newlines. \[OM-214\]
