Upgrade Guide

In September 2025, Pydantic AI reached V1, which means we're committed to API stability: we will not introduce changes that break your code until V2 (if we do, you can shout at us as it's definitely a mistake). Once we release V2, in April 2026 at the earliest, we'll continue to provide security fixes for V1 for another 6 months minimum, so you have time to upgrade your applications.

Breaking Changes

Here's a filtered list of the breaking changes for each version to help you upgrade Pydantic AI.

v1.0.1 (2025-09-05)

The following breaking change was accidentally left out of v1.0.0:

• See #2808 - Remove Python evaluator from pydantic_evals for security reasons

v1.0.0 (2025-09-04)

• See #2725 - Drop support for Python 3.9
• See #2738 - Make many dataclasses require keyword arguments
• See #2715 - Remove cases and averages attributes from pydantic_evals spans
• See #2798 - Change ModelRequest.parts and ModelResponse.parts types from list to Sequence
• See #2726 - Default InstrumentationSettings version to 2
• See #2717 - Remove errors when passing AsyncRetrying or Retrying object to AsyncTenacityTransport or TenacityTransport instead of RetryConfig

v0.x.x

Before V1, minor versions were used to introduce breaking changes:

v0.8.0 (2025-08-26)

See #2689 - AgentStreamEvent was expanded to be a union of ModelResponseStreamEvent and HandleResponseEvent, simplifying the event_stream_handler function signature. Existing code accepting AgentStreamEvent | HandleResponseEvent will continue to work.

v0.7.6 (2025-08-26)

The following breaking change was inadvertently released in a patch version rather than a minor version:

See #2670 - TenacityTransport and AsyncTenacityTransport now require the use of pydantic_ai.retries.RetryConfig (which is just a TypedDict containing the kwargs to tenacity.retry) instead of tenacity.Retrying or tenacity.AsyncRetrying.

v0.7.0 (2025-08-12)

See #2458 - pydantic_ai.models.StreamedResponse now yields a FinalResultEvent along with the existing PartStartEvent and PartDeltaEvent. If you're using pydantic_ai.direct.model_request_stream or pydantic_ai.direct.model_request_stream_sync, you may need to update your code to account for this.

See #2458 - pydantic_ai.models.Model.request_stream now receives a run_context argument. If you've implemented a custom Model subclass, you will need to account for this.

See #2458 - pydantic_ai.models.StreamedResponse now requires a model_request_parameters field and constructor argument. If you've implemented a custom Model subclass and implemented request_stream, you will need to account for this.

v0.6.0 (2025-08-06)

This release was meant to clean some old deprecated code, so we can get a step closer to V1.
