v2.42.0

• Sync and Async can now be invoked from a non-blocking fiber that has no scheduler (e.g. inside an Enumerator or a bare Fiber.new). Previously this raised RuntimeError: Running scheduler on non-blocking fiber!. The reactor is now run within Fiber.blocking, so the scheduler always runs on a blocking fiber.

v2.41.0

• Fixed: Protect initial task from Interrupt exceptions.

v2.40.0

• Introduce Async::Condition#waiting_count. This allows you to see how many tasks are currently waiting on the condition, which can be useful for debugging and monitoring purposes.

v2.39.0

• Async::Barrier#wait now returns the number of tasks that were waited for, or nil if there were no tasks to wait for. This provides better feedback about the operation, and allows you to know how many tasks were involved in the wait.

v2.38.1

• Fix Barrier#async when parent.async yields before the child block executes. Previously, Barrier#wait could return early and miss tracking the task entirely, because the task had not yet appended itself to the barrier's task list.

v2.38.0

• Rename Task#stop to Task#cancel for better clarity and consistency with common concurrency terminology. The old stop method is still available as an alias for backward compatibility, but it is recommended to use cancel going forward.
• Forward arguments from Task#wait -> Promise#wait, so task.wait(timeout: N) is supported.

v2.37.0

• Introduce Async::Loop for robust, time-aligned loops.
• Add support for Async::Promise#wait(timeout: N).
