Unreleased

  • Breaking: Remove workflow::Context::tx; step contexts no longer expose a worker transaction directly
  • Breaking: Workflow activities are now registered on Workflow::builder() before steps
  • Breaking: Remove manual activity keys; operation identity is now derived from workflow run ID, step index, and per-step operation order
  • Add: Runtime high-level orchestration API sourced from builder-registered activities
  • Breaking: Remove Workflow::run and Workflow::start; use workflow.runtime().run() / workflow.runtime().start()
  • Breaking: Remove Workflow::worker and Workflow::scheduler; use workflow.runtime().worker() / workflow.runtime().scheduler()
  • Add: Activity trait and standard activity error envelope
  • Add: Durable typed workflow::InvokeActivity helpers (A::call / A::emit) with compile-time registration checks
  • Add: waiting task state to support workflow suspension while activity calls complete
  • Breaking: Rename enqueue_multi to enqueue_many and return task IDs for batch enqueue
  • Perf: Optimize enqueue_many for uniform-config batches
  • Fix: Pending retry delays now respect the last attempt time when re-queuing tasks
  • Fix: Reap completed worker processing tasks to avoid unbounded memory growth
  • Fix: Fence reclaimed task attempts so stale workers cannot update task state
  • Fix: Workflow step configuration now uses the step index from input to avoid cross-run drift
  • Add: Workflow steps can configure task timeouts, TTLs, delays, heartbeats, concurrency keys, and priorities
  • Add: Workflow batch enqueue helpers (enqueue_many, enqueue_many_using)
  • Breaking: Rename workflow step transition type To to Transition, including helper constructors done -> complete and delay_for -> after

0.2.0

  • Breaking: Queues are now stored and passed as Arc<Queue<_>>; Worker::new and Scheduler::new take Arc<Queue<_>> instead of Queue<_>. #100
  • Breaking: Workflow::run_worker and Workflow::run_scheduler have been removed. #100
  • Breaking: Workflow::run and Workflow::start now take &self rather than consuming self. #100
  • Fix: Shutdown channels are now unique. #97
  • Add: Workflow::queue, Workflow::worker, and Workflow::scheduler helpers for zero‑boilerplate executor creation. #100
  • Add: enqueue_multi et al, allowing batched enqueue. #79

0.1.2

  • Provide additional worker and scheduler tracing instrumentation

0.1.1

  • Fix: Workflow cancellation should lock rows to be cancelled #67

0.1.0

  • Breaking: Worker and scheduler setters have been renamed #42
  • Breaking: Migrations have been reworked to compensate for features that will land in sqlx 0.9.0 #44
  • Breaking: Workflow enqueues now return an EnqueuedWorkflow type #46
  • Breaking: Task ID is now a newtype #47
  • Breaking: Task dequeues are now encapsulated such that they are visible as they're being processed #55, #59, #60, #64, #65
  • Breaking: Task schedule "name" column renamed to "task_queue_name" for consistency #58
  • Breaking: Scheduler iterator has been refactored to use Zoned directly #62
  • Task attempts are now recorded in a separate table, providing a complete log of task execution history #50

0.0.6

  • Breaking: Queue methods now take input by reference
  • Breaking: Workflow methods also take input by reference
  • Breaking: The scheduler run_every method is removed
  • Pending tasks are now processed upon change via a notify channel #25
  • An unschedule method is provided on Queue and Workflow #40
  • Graceful shutdown is now available on WorkflowHandle returned from start #37

0.0.5

  • Breaking: Tasks require an associated type Output
  • Breaking: Tasks require a transaction as their first execute argument
  • Breaking: Database locking methods are now free functions
  • Breaking: Workflow interface rewritten for step functions #24

0.0.4

  • Breaking: Renamed builders to Builder #15
  • Breaking: Made task deletion routine a free function #13
  • Breaking: Workflow::run now runs both the worker and scheduler #12
  • Ensure scheduler singleton behavior

0.0.3

  • Added ToTaskResult trait for better task result ergonomics #10

0.0.2

  • Workflows may provide state #9
  • Breaking: queue must now be defined after execute
  • Workers may be gracefully shutdown via graceful_shutdown #8
