Changelog

0.2.4 - 2026-02-09

• ClojureScript support. The core task API now works on both Clojure and ClojureScript. See README for platform-specific differences.
• gate / gate-task (new); cross-platform concurrency limiter. Creates a gate with N permits; gate-task runs work through the gate, queueing if no permits are available. Gates participate in structured concurrency (cancelling a gate cancels all gated tasks) and are reentrant (nested gate-task calls on the same gate don't consume additional permits).
• cancel now accepts any ICancellable, not just tasks. This allows cancelling gates directly.
• Promises can now be cancelled. Cancelling a promise sets the cancelled? flag and propagates cancellation (not failure) to chained tasks, consistent with task cancellation semantics.
• abort-signal / aborted? / comply-abort (new, CLJS only); create an AbortSignal tied to the current task's lifecycle. The signal is aborted when the task settles (completes, fails, or is cancelled), enabling automatic cleanup of fetch requests and other AbortSignal-aware APIs.
• as-jsp (new, CLJS only); convert a task to a JavaScript Promise. The CLJS counterpart to as-cf.
• Task coordination performance improvements. The subscription system now uses a lock-free intrusive deque instead of a ConcurrentHashMap, improving scalability when many sibling tasks are started concurrently within a single parent. Except for race, the entire implementation is now lock-free.

0.1.14 - 2026-01-15

• Docstring formatting improvements for cljdoc rendering (Args sections now use markdown lists).
• Added function examples to sleep and timeout docstrings.
• Renamed err1/err2/... parameters to e1/e2/... in catch and catch-cpu for consistency.

0.1.12 - 2026-01-14

• race-stateful; Fixed bug where racing the same task multiple times could incorrectly release the winning result, or could attempt to release the same losing result multiple times. Now, winning results will not be released, and losing results will be released exactly once. Introduces a constraint: release will not run on nil due to underlying constraints. This is OK, nil is not stateful.

0.1.11 - 2026-01-13

• time (new); measure the time it takes to execute a task. Takes a function that receives the args of finally plus a Duration that estimates the time it took to run the task.
• monitor no longer incorrectly breaks cascading cancellation chain.

0.1.10 - 2026-01-12

• CPU executor now uses a work-stealing ForkJoinPool instead of a fixed thread pool, since it's reasonable to expect CPU bound work of variable duration.
• CPU executor pool size reduced from 2 * number-of-cores to number-of-cores. With platform parking throwing by default, the previous precaution should be unnecessary.
• Cancelled CompletableFuture now propagates as task cancellation rather than exception. Previously, cancellations would propagate as if they were exceptions, causing the Quiescent task to go into exception handling (e.g. catch) rather than exclusively teardown handling (finally).

0.1.9 - 2026-01-08

• Bump pathling to 0.1.8

0.1.8 - 2026-01-03

• Bump scoped to 0.1.14
• Bump machine-latch to 0.1.12

0.1.7 - 2026-01-05

• race now cancels the "winner" task if all participants in the race are cancelled.
• await does not explicitly take a phase to await. It's now equivalent to deref, but returns a boolean rather than returning a value or throwing an exception.

0.1.6 - 2026-01-05

Replace weak references with mutual cleanup

Previously, tasks occasionally held a weak reference to one another to allow for GC to occur even though eg. a parent held a reference (for potential cancellation) to a child.

This is now replaced with a mutual cleanup instead. For task A and B, if A wants to be able to cancel B, it will have a strong reference to B. But if B passes the stage where it can be cancelled, it will remove this subscription from A.

This is also more performant than hanging on to the weak references, and estimated performance numbers have been lowered in accordance.

0.1.5 - 2026-01-03

• Bump scoped to 0.1.13

0.1.4 - 2026-01-02
