* [ENHANCEMENT] Update package `uber.go/auomaxprocs` to support `cgroups2`#10584
This Prometheus release is built with go1.18, which contains two noticeable changes related to TLS:
* [BUGFIX] Tracing/GRPC: Set TLS credentials only when insecure is false. #10592
* [BUGFIX] Agent: Fix ID collision when loading a WAL with multiple segments. #10587
* [BUGFIX] Revoke storing target and metadata cache in context. This can fix a memory link introduced in `2.35.0-rc0`#10590
## 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
