Version v0.2.8 introduces round‑robin API key rotation and fixes counter overflows, but it breaks existing API key management workflows that do not use the new configuration.

Why it matters: The breaking change (severity 70) disables current API key management unless you reconfigure for round‑robin; developers must update their workflows before upgrade.
