• Deleted or renamed enum value PolicySettingsDefaultCustomBlockResponseStatusCode.TWO_HUNDRED
• Deleted or renamed enum value PolicySettingsDefaultCustomBlockResponseStatusCode.FOUR_HUNDRED_THREE
• Deleted or renamed enum value PolicySettingsDefaultCustomBlockResponseStatusCode.FOUR_HUNDRED_FIVE
• Deleted or renamed enum value PolicySettingsDefaultCustomBlockResponseStatusCode.FOUR_HUNDRED_SIX
• Deleted or renamed enum value PolicySettingsDefaultCustomBlockResponseStatusCode.FOUR_HUNDRED_TWENTY_NINE

Accepted breaking changes (will remain)

Per the SDK breaking-changes guide for TypeSpec migration, these changes are intentional and follow the new model-hierarchy / API-design rules:

Multi-level flattening removal (guide §11)

Flattened properties on the following models now nest under .properties:
AFDDomain, AFDDomainUpdateParameters, AFDEndpoint, AFDEndpointUpdateParameters, AFDOrigin, AFDOriginUpdateParameters, AFDOriginGroup, AFDOriginGroupUpdateParameters, CanMigrateResult, CustomDomainParameters, Endpoint, EndpointUpdateParameters, Operation, Origin, OriginUpdateParameters, OriginGroup, OriginGroupUpdateParameters, ProfileUpdateParameters, Route, RouteUpdateParameters, Rule, RuleUpdateParameters, RuleSet, Secret, SecurityPolicy, SecurityPolicyUpdateParameters.

Removed models (guide §7 / §8)

• Pageable list wrappers: CdnWebApplicationFirewallPolicyList, ManagedRuleSetDefinitionList, EdgenodeResult.
• Unreferenced / replaced models: AzureFirstPartyManagedCertificate, Certificate, CustomerCertificate, ManagedCertificate, ValidationToken, DeliveryRuleActionEnum (replaced by enum DeliveryRuleActionName).

Keyword-only parameters (guide §9)

All query/header parameters on LogAnalyticsOperations.get_log_analytics_metrics, get_log_analytics_rankings, get_waf_log_analytics_metrics, and get_waf_log_analytics_rankings are now keyword-only. Users should switch positional calls to keyword form.

Notes

• This SDK output was regenerated from the TypeSpec HEAD at eb08171f and reflects the spec before the mitigation PR is merged. After the spec PR is merged, regenerate to apply the Python @@clientName overrides and the changelog should shrink accordingly.
