# Migrating from 0.x.x

> Upgrade from any pre-1.0.0 SDK release (0.x.x and 1.0.0-dev)

Version 1.0.0 of both SDKs is generated directly from the public OpenAPI specification,
and every method is named after its API operation. If you are upgrading from any release
prior to 1.0.0 (all `0.x.x` versions, and the `1.0.0-dev` pre-releases on PyPI), method
names have changed — for example:

<CodeGroup>
  ```diff TypeScript theme={null}
  - const session = await client.sessions.create({ session: { recording: { active: false } } });
  + const session = await Sessions.createSession({ body: { session: { recording: { active: false } } } });
  ```

  ```diff Python theme={null}
  - session = client.sessions.create(session={"recording": {"active": False}})
  + session = client.sessions.create_session(session={"recording": {"active": False}})
  ```
</CodeGroup>

In TypeScript the client itself also changed (a shared configurable instance instead of a
constructed class); in Python the client construction, error types, retries and timeouts are
unchanged — only method names and a few subsurfaces moved.

## Requirements

* **TypeScript**: no runtime requirement changes.
* **Python**: Python 3.10+ (was 3.9+) and pydantic v2 (`>= 2, < 3`) — pydantic v1 is no
  longer supported, and `pip` will refuse to resolve `anchorbrowser >= 1.0.0` alongside
  `pydantic < 2`. Every other dependency keeps the same version range.

## Full migration guides

Each repository ships a complete guide covering every breaking change and its 1.0
equivalent, including the full method rename table:
