Release Notes

Ptrskay3/axum-prometheus (axum-prometheus)

### [`v0.6.1`](https://togithub.com/Ptrskay3/axum-prometheus/blob/HEAD/CHANGELOG.md#061---2024-01-23) [Compare Source](https://togithub.com/Ptrskay3/axum-prometheus/compare/0.6.0...0.6.1) - Disabled the `"push-gateway"` feature in `metrics-exporter-prometheus` by default, and added a way to enable it via the same name under `axum_prometheus`. This change ensures that this crate can still be built without openssl support, see [here](https://togithub.com/Ptrskay3/axum-prometheus/issues/42). \[[#​44](https://togithub.com/Ptrskay3/axum-prometheus/issues/44)] - Update examples to `metrics-exporter-prometheus` to `0.13` and `metrics` to `0.22`. \[[#​43](https://togithub.com/Ptrskay3/axum-prometheus/issues/43)]
