**Default API Version Update**: Changed the SDK default API version from `2026-06-01-preview` to the GA version `2026-07-15`. Pass `api_version="2026-06-01-preview"` explicitly to keep the previous default behavior.

Renamed class `TaskGenerationDataGenerationJobOptions` to `SimulationSeedDataGenerationJobOptions`. The corresponding `DataGenerationJobType.TASK_GENERATION` enum member was renamed to `DataGenerationJobType.SIMULATION_SEED`, and its wire value changed from `task_generation` to `simulation_seed`.

Renamed enum `OptimizationDatasetInputType` to `AgentOptimizationDatasetInputType`.

Renamed class `OptimizationAgentIdentifier` to `OptimizedAgentIdentifier`.

Renamed class `OptimizationCandidate` to `AgentOptimizationCandidate`.

Methods `.beta.routines.list` and `.beta.routines.list_runs` replaced the `before` argument with `after` and now use the service-provided `next_link` for continuation.

Method `.beta.datasets.create_generation_job` renamed to `.beta.datasets.begin_create_generation_job` and is now a long-running operation returning `LROPoller[DataGenerationJobResult]`.

Method `.beta.agents.create_optimization_job` renamed to `.beta.agents.begin_create_optimization_job` and is now a long-running operation returning `LROPoller[OptimizationJobResult]`.

Method `.beta.evaluators.create_generation_job` renamed to `.beta.evaluators.begin_create_generation_job` and is now a long-running operation returning `LROPoller[EvaluatorVersion]` (previously returned `EvaluatorGenerationJob`).

Removed `ResponseContext.conversation_chain_metadata` and the `ConversationChainMetadataNamespace` protocol. Resilient response applications now persist cross-turn state explicitly with `FoundryStateStore`.

Removed the duplicate `azure.ai.agentserver.responses.get_input_expanded` export. Import it from `azure.ai.agentserver.responses.models` instead.

Removed `TaskMetadata`, `TaskContext.metadata`, and `TaskRun.metadata`. Durable application state now belongs in an explicit `FoundryStateStore` and no longer shares task lifecycle PATCHes or lease renewal. Typed task inputs may carry a top-level `call_id`, which the framework restores in `FoundryAgentRequestContext` for every handler attempt.

Removed the unused public `AgentServerHost.sse_keepalive_stream` helper.

Removed the `POST /api/messages` route alias. Inbound activities are served only at `POST /activity/messages`, which is the endpoint the Foundry platform routes to. Callers that posted to `/api/messages` must use `/activity/messages`.

Removed public SSE keepalive helper.
