## [2.7.0](https://github.com/google/adk-python/compare/v2.6.3...v2.7.0) (2026-08-13) ### Highlights A correctness release: most of the work went into what an agent sends to the model and what it gets back, alongside a long tail of fixes across tools, sessions, evaluation and the CLI. * **Models declare their own capabilities**: an agent pairs an output schema with tools when the model actually supports it, instead of ADK inferring support from the model id.
