 ## [Unreleased]
 
+### Fixed
+
+- Ensure unused worker usage statistics are deleted at runtime.
+
+### Changed
+
+- Rename worker choice strategy options `choiceRetries` to `retries`.
+
+## [2.6.36] - 2023-08-27
+
+### Fixed
+
+- Fix pool `execute()` arguments check.
+
+### Changed
+
+- Make continuous tasks stealing algorithm less aggressive.
+- Fine tune tasks stealing algorithm under back pressure.
+
+## [2.6.35] - 2023-08-25
+
+### Fixed
+
+- Don't account worker usage statistics for tasks that have failed.
+- Fix pool information runtime and wait time median computation.
+
+### Changed
+
+- Update simple moving average implementation to use a circular buffer.
+- Update simple moving median implementation to use a circular buffer.
+- Account for stolen tasks in worker usage statistics and pool information.
+
+### Added
+
+- Continuous tasks stealing algorithm.
+
+## [2.6.34] - 2023-08-24
+
+### Fixes
+
+- Avoid cascading tasks stealing under back pressure.
+
+### Changed
+
+- Add fastpath to queued tasks rescheduling.
+
+## [2.6.33] - 2023-08-24
+
+### Fixed
+
+- Fix queued tasks rescheduling.
+
+### Changed
+
+- Rename tasks queue options `queueMaxSize` to `size`.
+
+### Added
+
+- Task stealing scheduling algorithm if tasks queueing is enabled.
+
+## [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.
+
