We need a little more updates because e.g. our cargo-audit can’t parse the newest advisory-db:

+++ command cargo audit -n -d /nix/store/pnan3cm2da66cs7mcshpxg44ayj6qyh7-source --ignore yanked
error: error loading advisory database: parse error: error parsing /nix/store/pnan3cm2da66cs7mcshpxg44ayj6qyh7-source/crates/pingora-core/RUSTSEC-2026-0034.md: parse error: TOML parse error at line 9, column 8

unsupported CVSS version: 4.0

Maybe let’s do it after release? 👀
