### Release Notes

<summary>prometheus/client_golang
(github.com/prometheus/client_golang)</summary>

###
[`v1.20.5`](https://redirect.github.com/prometheus/client_golang/releases/tag/v1.20.5):
/ 2024-10-15

[Compare
Source](https://redirect.github.com/prometheus/client_golang/compare/v1.20.4...v1.20.5)

We decided to revert [the `testutil`
change](https://redirect.github.com/prometheus/client_golang/pull/1424)
that made our util functions less error-prone, but created a lot of work
for our downstream users. Apologies for the pain! This revert should not
cause any major breaking change, even if you already did the
work--unless you depend on the [exact error
message](https://redirect.github.com/grafana/mimir/pull/9624#issuecomment-2413401565).

Going forward, we plan to reinforce our release testing strategy
[\[1\]](https://redirect.github.com/prometheus/client_golang/issues/1646),[\[2\]](https://redirect.github.com/prometheus/client_golang/issues/1648)
and deliver an enhanced [`testutil`
package/module](https://redirect.github.com/prometheus/client_golang/issues/1639)
with more flexible and safer APIs.

##### Changelog

\[BUGFIX] testutil: Reverted
