1. Pydantic AI v2.14.0 Adds Mistral Reasoning-Effort Control and Durability Integrations

Pydantic AI. Pydantic AI released v2.14.0, adding reasoning_effort support for Mistral via thinking settings for finer control over model behavior. The release also introduces three durability integrations, TemporalDurability, DBOSDurability, and PrefectDurability, replacing the deprecated wrapper-agent approach, and removes shut-down Gemini preview models. For teams building long-running agents, the new durability options make it easier to persist and resume agent state across failures. Source
