## [Unreleased]
+## [2.6.32] - 2023-08-23
+
+### Fixed
+
+- Ensure no task can be executed when the pool is destroyed.
+
+### Added
+
+- Add `queueMaxSize` option to tasks queue options.
+- Add O(1) deque implementation implemented with doubly linked list and use it for tasks queueing.
+- Add tasks stealing algorithm when a worker node queue is back pressured if tasks queueing is enabled.
+
+## [2.6.31] - 2023-08-20
+
+### Fixed
+
+- Fix worker choice strategy retries mechanism in some edge cases.
+
+### Changed
+
+- Make orthogonal worker choice strategies tasks distribution and created dynamic worker usage.
+- Remove the experimental status of the `LEAST_ELU` worker choice strategy.
+
+## [2.6.30] - 2023-08-19
+
+### Fixed
+
+- Ensure pool event `backPressure` is emitted.
+- Ensure pool event `full` is emitted only once.
+- Ensure worker node cannot be instantiated without proper arguments.
+
+## [2.6.29] - 2023-08-18
+
+### Fixed
+
+- Fix race condition between ready and task functions worker message handling at startup.
+- Fix duplicate task function worker usage statistics computation per task function.
+- Update task function worker usage statistics if and only if there's at least two different task functions.
+- Fix race condition at task function worker usage executing task computation leading to negative value.
+
+### Added
+
+- Add back pressure detection on the worker node queue. Event `backPressure` is emitted when all worker node queues are full (worker node queue size >= poolMaxSize^2).
+- Use back pressure detection in worker choice strategies.
+- Add worker choice strategies retries mechanism if no worker is eligible.
+
+## [2.6.28] - 2023-08-16
+
+### Fixed
+
+- Ensure pool workers are properly initialized.
+
+### Added
+
+- HTTP server pool examples: express-cluster, express-hybrid.
+
+### Changed
+
+- Remove now useless branching in worker hot code path.
+
+## [2.6.27] - 2023-08-15
+
+### Fixed
+
+- Add `KillHandler` type definition to exported types.
+
+### Added
+
+- Add `destroy` event to pool API.
+
+## [2.6.26] - 2023-08-15
+
+### Added
+
+- Add kill handler to worker options allowing to execute custom code when worker is killed.
+- Add `listTaskFunctions()` method to pool API.
+- SMTP server pool example: nodemailer.
+
+## [2.6.25] - 2023-08-13
+
+### Added
+
+- HTTP server pool examples: fastify-cluster, fastify-hybrid.
+- WebSocket server pool examples: ws-cluster, ws-hybrid.
+
+## [2.6.24] - 2023-08-12
+
### Added
- Add array of transferable objects to the `execute()` method arguments.
+- WebSocket server pool examples: ws-worker_threads.
## [2.6.23] - 2023-08-11
### Added
- HTTP client pool examples: fetch, node-fetch and axios with multiple task functions.
-- HTTP server pool examples: express, fastify.
+- HTTP server pool examples: express-worker_threads, fastify-worker_threads.
## [2.6.22] - 2023-08-10
### Fixed
- Fix queued tasks redistribution on error task execution starvation.
-- Ensure task queueing per worker condition is untangled from the pool busyness semantic.
+- Ensure tasks queueing per worker condition is untangled from the pool busyness semantic.
### Changed
### Added
-- Add `listTaskFunctions()` method to worker class.
+- Add `listTaskFunctions()` method to worker API.
## [2.6.16] - 2023-07-12
### Added
-- Add safe helper `availableParallelism` to help sizing the pool.
+- Add safe helper `availableParallelism()` to help sizing the pool.
### Fixed
### Fixed
- Artificial version bump to 2.6.5 to workaround publication issue.
-- Ensure cluster pool destroy() gracefully shutdowns worker's server.
+- Ensure cluster pool `destroy()` gracefully shutdowns worker's server.
- Ensure pool event is emitted before task error promise rejection.
- Fix queued tasks count computation.
