Release v1.34.0 adds PayGo billing options and several new models (VEO‑3.1‑lite‑generate‑001, Gemini 3.1 Flash Lite) to the Google GenAI plugin while fixing middleware and validation bugs.

Why it matters: Patch immediately for bug fixes; evaluate PayGo support if using priority/flex billing and test new model integrations in development before production rollout.
