Breaking Changes

●Issue #1

Import paths changed from `from auth0.management import Auth0` to `from auth0.management import ManagementClient`.

●Issue #2

Client initialization changed from `Auth0(domain, management_token)` to `ManagementClient(domain, client_id, client_secret)` with automatic token management.

●Issue #3

Response types changed from dictionaries to Pydantic models (use `.model_dump()` to convert back to dict).

●Issue #4

Method organization changed from flat (`client.users.list()`) to hierarchical where applicable.

●Issue #5

Pagination parameters changed - some endpoints use `per_page`, others use `take`.

●Issue #6

Python version requirement increased from ≥3.7 to ≥3.8.

●Issue #7

Error handling changed from `Auth0Error` to `ApiError` base class.

Migration Steps

1
Update import paths from `from auth0.management import Auth0` to `from auth0.management import ManagementClient`.
2
Update client initialization to use `ManagementClient(domain, client_id, client_secret)` instead of `Auth0(domain, management_token)`.
3
Update code to handle Pydantic models as responses; use `.model_dump()` if a dictionary is required.
4
Review method calls for hierarchical structure changes.
5
Review pagination parameter usage; check if endpoints now use `take` instead of `per_page` or vice versa.
6
Ensure Python version is ≥3.8.
7
Update error handling to catch `ApiError` instead of `Auth0Error`.
