## Short answer
Follow the official changelog or release-note page for every provider you actively use, plus its deprecations or shutdown page if available. OpenAI, Anthropic, Gemini, DeepSeek, Mistral, xAI, and OpenRouter all publish enough primary-source change data now that third-party summaries should be secondary.
