 680 ## [2.3.1] - 2022-10-13
 681
 682 ### Added
 683
 684 - Pool worker choice strategies:
 685   - `WorkerChoiceStrategies.WEIGHTED_ROUND_ROBIN` strategy based on weighted round robin scheduling algorithm using tasks execution time for now.
 686   - `WorkerChoiceStrategies.FAIR_SHARE` strategy based on fair share scheduling algorithm using tasks execution time for now.
 687
 688 ## [2.2.2] - 2022-10-09
 689
 690 ### Fixed
 691
 692 - Fixed `README.md` file.
 693
 694 ## [2.2.1] - 2022-10-08
 695
 696 ### Added
 697
 698 - Dynamic worker choice strategy change at runtime.
 699
 700 ## [2.2.0] - 2022-01-05
 701
 702 ### Breaking Changes
 703
 704 - Support only Node.js version 16.x.x for cluster pool: upstream cluster API have changed on that version.
 705
 706 ## [2.1.0] - 2021-08-29
 707
 708 ### Added
 709
 710 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
 711
 712 ### Breaking Changes
 713
 714 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
 715 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
 716 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
 717 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
 718
 719 ## [2.0.2] - 2021-05-12
 720
 721 ### Bug fixes
 722
 723 - Fix `busy` event emission on fixed pool type
 724
 725 ## [2.0.1] - 2021-03-16
 726
 727 ### Bug fixes
 728
 729 - Check if pool options are properly set.
 730 - `busy` event is emitted on all pool types.
 731
 732 ## [2.0.0] - 2021-03-01
 733
 734 ### Bug fixes
 735
 736 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
 737
 738 ### Breaking Changes
 739
 740 - `FullPool` event is now renamed to `busy`.
 741 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
 742   _Find more details on our JSDoc._
 743
 744 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
 745
 746 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
 747
 748 ### Pool options types declaration merge
 749
 750 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
 751
 752 #### New `export` strategy
 753
 754 ```js
 755 // Before
 756 const DynamicThreadPool = require('poolifier/lib/dynamic')
 757 // After
 758 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
 759 ```
 760
 761 But you should always prefer just using
 762
 763 ```js
 764 const { DynamicThreadPool } = require('poolifier')
 765 ```
 766
 767 #### New type definitions for input data and response
 768
 769 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
 770 _This is not a limitation by poolifier but Node.js._
 771
 772 #### Public property replacements
 773
 774 `numWorkers` property is now `numberOfWorkers`
 775
 776 #### Internal (protected) properties and methods renaming
 777
 778 These properties are not intended for end users
 779
 780 - `id` => `nextMessageId`
 781
 782 These methods are not intended for end users
 783
 784 - `_chooseWorker` => `chooseWorker`
 785 - `_newWorker` => `createWorker`
 786 - `_execute` => `internalExecute`
 787 - `_chooseWorker` => `chooseWorker`
 788 - `_checkAlive` => `checkAlive`
 789 - `_run` => `run`
 790 - `_runAsync` => `runAsync`
 791
 792 ## [1.1.0] - 2020-05-21
 793
 794 ### Added
 795
 796 - ThreadWorker support async functions as option
 797 - Various external library patches
 798
 799 ## [1.0.0] - 2020-01-24
 800
 801 ### Added
 802
 803 - FixedThreadPool implementation
 804 - DynamicThreadPool implementation
 805 - WorkerThread implementation to improve developer experience
