+## Overall changes
+
+v6 removes one deprecated Management API surface (federated connections
+tokensets) and tightens a handful of generated types to match the current
+Auth0 Management API contract. Most applications will only be affected if
+they use the specific types or endpoints listed below.
+
+The Authentication API is not affected by this release.
+
+## Breaking changes
+
+### Federated connections tokensets removed
+
+The `users.federated_connections_tokensets` sub-client and its `list`/`delete`
+methods have been removed, along with the `FederatedConnectionTokenSet` and
+`ConnectionFederatedConnectionsAccessTokens` types. This endpoint is no longer
+part of the Auth0 Management API.
+
+```python
+# v5
+client.users.federated_connections_tokensets.list(id="user_id")
+client.users.federated_connections_tokensets.delete(id="user_id", tokenset_id="tokenset_id")
+```
+
+```python
+# v6
+# No replacement — the endpoint has been removed from the Management API.
+```
+
+If you depend on this functionality, do not upgrade until you have confirmed
+an alternative with Auth0 support.
+
+### `federated_connections_access_tokens` field removed
+
+The optional `federated_connections_access_tokens` field has been removed
+from:
+
+- `ConnectionOptionsAzureAd`
+- `ConnectionOptionsCommonOidc`
+- `ConnectionOptionsGoogleApps`
+- `ConnectionPropertiesOptions`
+- `UpdateConnectionOptions`
+
+Any code reading or setting this field on the above types will need to
+remove that usage. Note that these models are configured with
+`extra="allow"`, so passing `federated_connections_access_tokens` is **not**
+silently dropped — it is retained on the model and still serialized into the
+outbound request. Remove the field explicitly rather than relying on the SDK
+to strip it.
+
+### `read:federated_connections_tokens` / `delete:federated_connections_tokens` scopes removed
+
+These two values are no longer valid members of `OauthScope`. Remove any
+references to them when requesting or checking scopes.
+
+### `ClientSessionTransferDelegationDeviceBindingEnum` narrowed
+
+The `"asn"` literal value has been removed. The enum now only accepts `"ip"`:
+
+```python
+# v5
+ClientSessionTransferDelegationDeviceBindingEnum = typing.Union[typing.Literal["ip", "asn"], typing.Any]
+```
+
+```python
+# v6
+ClientSessionTransferDelegationDeviceBindingEnum = typing.Union[typing.Literal["ip"], typing.Any]
+```
+
+If you were setting this value to `"asn"`, update it to `"ip"` — this matches
+the current Management API's accepted values.
+
+### `ConnectionAttributeIdentifier` split into three types
+
+`ConnectionAttributeIdentifier` has been removed with no compatibility alias.
+It is replaced by three narrower types, one per attribute:
+
+| Attribute field | v5 type | v6 type | Shape |
+| --- | --- | --- | --- |
+| `EmailAttribute.identifier` | `ConnectionAttributeIdentifier` | `EmailAttributeIdentifier` | `{active?, default_method?: DefaultMethodEmailIdentifierEnum}` |
+| `PhoneAttribute.identifier` | `ConnectionAttributeIdentifier` | `PhoneAttributeIdentifier` | `{active?, default_method?: DefaultMethodPhoneNumberIdentifierEnum}` |
+| `UsernameAttribute.identifier` | `ConnectionAttributeIdentifier` | `UsernameAttributeIdentifier` | `{active?}` (no `default_method`) |
+
+```python
+# v5
+from auth0.management.types import ConnectionAttributeIdentifier
+
+identifier = ConnectionAttributeIdentifier(active=True, default_method="email_otp")
+```
+
+```python
+# v6
+from auth0.management.types import EmailAttributeIdentifier
+
+identifier = EmailAttributeIdentifier(active=True, default_method="email_otp")
+```
+
+`EmailAttributeIdentifier` has the same shape as the old
+`ConnectionAttributeIdentifier` and is a drop-in replacement for code that
+was only ever used with `EmailAttribute`. Code using
+`ConnectionAttributeIdentifier` with `PhoneAttribute` or `UsernameAttribute`
+must switch to `PhoneAttributeIdentifier` or `UsernameAttributeIdentifier`
+respectively; `UsernameAttributeIdentifier` does not support
+`default_method`.
+
+### `PhoneProviderProtectionBackoffStrategyEnum` value renamed
+
+The `"none"` literal has been replaced with `"default"`:
+
+```python
+# v5
+PhoneProviderProtectionBackoffStrategyEnum = typing.Union[typing.Literal["exponential", "none"], typing.Any]
+```
+
+```python
+# v6
+PhoneProviderProtectionBackoffStrategyEnum = typing.Union[typing.Literal["exponential", "default"], typing.Any]
+```
+
+Replace any use of `"none"` with `"default"`.
+
+### `ListRolesOffsetPaginatedResponseContent` pagination fields now required
+
+`start`, `limit`, and `total` are no longer optional:
+
+```python
+# v5
+start: typing.Optional[float] = None
+limit: typing.Optional[float] = None
+total: typing.Optional[float] = None
+```
+
+```python
+# v6
+start: float
+limit: float
+total: float
+```
+
+Deserializing a role-list response that is missing any of these fields now
+raises `pydantic.ValidationError` instead of silently defaulting to `None`.
+This matches the Management API, which always returns these fields for this
+endpoint.
