AI learning answer

Which AI release notes should I actually follow?

Short answer from Learnetto's Best AI resources for model release notes and migrations guide.

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.
