[SDK Ergonomics] NEXUS-519: Add link to QueryWorkflowResponse For Nexus Operations. Query is both read-only and sync- so 1. no callbacks 2. the link is only from caller to the handler- and is specifically a workflow link as there isnt a history event in handler for query

Add standalone activity start delay to namespace capabilities (#833) **What changed?** Added the standalone_activity_start_delay field to NamespaceInfo.Capabilities. **Why?** Clients need to determine whether standalone activity start delay is effectively available for a namespace without relying on server-version checks. This lets UI clients hide start-delay controls when the feature is disabled by server configuration. --------- Co-authored-by: Sean Kane <sean.kane@temporal.io>

Add ACTIVITY_EXECUTION_STATUS_PAUSED

feat: support batch operations on standalone activities (#806) **What changed?** Support batch Terminate, RequestCancellation, and Delete for standalone activities. **Why?** This will have parity with workflow where we can perform these batch operations. **Breaking changes** None **Server PR** [PR#10803](https://github.com/temporalio/temporal/pull/10803) --------- Co-authored-by: Kundan <281732484+ks-temporal@users.noreply.github.com>

add wait time skipping completion in describe workflow execution

2026-07-15

add TimeSkippingInfo

remove PollTimeSkippingInfo and add the feature to describe workflow

Add execution_time to ActivityExecutionListInfo (#825) **What changed?** Add execution_time (field 12) to ActivityExecutionListInfo, mirroring the existing field on ActivityExecutionInfo. **Why?** So list responses expose the effective dispatch time (schedule_time + start_delay) without fetching full execution info.

add VerisioningOverride to Child Workflow's on start (#798) **What changed?** - WISOTT **Why?** - Versioning <!-- Are there any breaking changes on binary or code level? --> **Breaking changes** - None <!-- If this breaks the Server, please provide the Server PR to merge right after this PR was merged. --> **Server PR** https://github.com/temporalio/temporal/pull/10646

remove reset_heartbeats field in ResetActivityExecutionRequest (#820) **What changed?** Remove the `reset_heartbeat` field from `temporal.api.workflowservice.v1.ResetActivityExecutionRequest`. **Why?** The new default behavior will be to reset heartbeats with a reset request so this field is no longer needed. **Breaking changes** This is _technically_ a breaking change, but this endpoint has not been published in the server yet so no users can actually use this field. <!-- If this breaks the Server, please provide the Server PR to merge right after this PR was merged. --> **Server PR** N/A

Update comment

Address feedback on Worker Callbacks (#828) > ℹ️ This is a PR to merge into the `feature/worker-callbacks` branch and not `main`. > So things like breaking API changes aren't as much of a concern. Creating PRs like this is to just make it easier to track changes and their justifications as the feature evolves. --- **What changed?** Add a new `CompletionHandler` link variant for operations to their completion handlers, and operations spawned from a completion handler. The thinking is that for any completion handler invocation we'd see 2x of these. One on the "source" resource, with the `CompletionHandler::handler` linking to whatever resource/execution performed the completion. And one on the resource/execution performing the completion, with `CompletionHandler::source` pointing to the source resource. An opaque `string id` field is included to differentiate worker callbacks, since multiple could be attached. However, these are all defined sever-side when we attach the completion handlers. In order to better define the "service contract users will need to define", the `nexus.OnCompleteHandlerInput` was moved into a separate `notificationservice/v1` folder. And has `OnCompletionHandler{ Request, Response }` protos. For the `OnCompleteHandlerInput`, there were a few minor changes as well: - Make the `SourceOperation` a variant, allowing for Workflows and Activities as source operations in the future. - Removed the `Links` field (at least for the `NexusOperation` message) since it would be redundant with the links supplied to the `StartNexusOperationOptions` that would be sent. - Add a pithy comment about the maximum size of the source context (to be enforced server-side in a later PR).

add a new workflow task failure cause for workflow pause (#821) **What changed?** Add a new `WorkflowTaskFailedCause` enum `WORKFLOW_TASK_FAILED_CAUSE_NOT_STARTED_TASK_PAUSED_WORKFLOW` **Why?** A new failure cause when a workflow task is scheduled but never started when a workflow is paused by an operator. The workflow task will be failed with this new cause. **Breaking changes** N/A **Server PR** Not needed
