Release Notes
prometheus/client_golang (github.com/prometheus/client_golang)
### [`v1.19.0`](https://togithub.com/prometheus/client_golang/releases/tag/v1.19.0)
[Compare Source](https://togithub.com/prometheus/client_golang/compare/v1.18.0...v1.19.0)
#### What's Changed
The module `prometheus/common v0.48.0` introduced an incompatibility when used together with client_golang (See [https://github.com/prometheus/client_golang/pull/1448](https://togithub.com/prometheus/client_golang/pull/1448) for more details). If your project uses client_golang and you want to use `prometheus/common v0.48.0` or higher, please update client_golang to v1.19.0.
