This Prometheus release is built with go1.18, which contains two noticeable changes related to TLS:
## 2.35.0-rc0 / 2022-04-08
* [TLS 1.0 and 1.1 disabled by default client-side](https://go.dev/doc/go1.18#tls10).
Prometheus users can override this with the `min_version` parameter of [tls_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#tls_config).
* [Certificates signed with the SHA-1 hash function are rejected](https://go.dev/doc/go1.18#sha1). This doesn't apply to self-signed root certificates.
* [CHANGE] promtool: Add new flag `--lint` (enabled by default) for the commands `check rules` and `check config`, resulting in a new exit code (`3`) for linter errors. #10435
* [FEATURE] Support for automatically setting the variable `GOMAXPROCS` to the container CPU limit. Enable with the flag `--enable-feature=auto-gomaxprocs`#10498
