983 ## [2.3.3] - 2022-10-15
987 - Add support for [cluster settings](https://nodejs.org/api/cluster.html#cluster_cluster_settings) in cluster pool options.
989 ## [2.3.2] - 2022-10-14
993 - Optimize fair share worker selection strategy implementation.
997 - Fix WRR worker selection strategy: ensure the condition triggering the round robin can be fulfilled.
999 ## [2.3.1] - 2022-10-13
1003 - Pool worker choice strategies:
1004 - `WorkerChoiceStrategies.WEIGHTED_ROUND_ROBIN` strategy based on weighted round robin scheduling algorithm using tasks execution time for now.
1005 - `WorkerChoiceStrategies.FAIR_SHARE` strategy based on fair share scheduling algorithm using tasks execution time for now.
1007 ## [2.2.2] - 2022-10-09
1011 - Fixed `README.md` file.
1013 ## [2.2.1] - 2022-10-08
1017 - Dynamic worker choice strategy change at runtime.
1019 ## [2.2.0] - 2022-01-05
1021 ### Breaking Changes
1023 - Support only Node.js version 16.x.x for cluster pool: upstream cluster API have changed on that version.
1025 ## [2.1.0] - 2021-08-29
1029 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
1031 ### Breaking Changes
1033 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
1034 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
1035 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
1036 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
1038 ## [2.0.2] - 2021-05-12
1042 - Fix `busy` event emission on fixed pool type
1044 ## [2.0.1] - 2021-03-16
1048 - Check if pool options are properly set.
1049 - `busy` event is emitted on all pool types.
1051 ## [2.0.0] - 2021-03-01
1055 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
1057 ### Breaking Changes
1059 - `FullPool` event is now renamed to `busy`.
1060 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1061 _Find more details on our JSDoc._
1063 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1065 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1067 ### Pool options types declaration merge
1069 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1071 #### New `export` strategy
1075 const DynamicThreadPool = require('poolifier/lib/dynamic')
1077 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1080 But you should always prefer just using
1083 const { DynamicThreadPool } = require('poolifier')
1086 #### New type definitions for input data and response
1088 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1089 _This is not a limitation by poolifier but Node.js._
1091 #### Public property replacements
1093 `numWorkers` property is now `numberOfWorkers`
1095 #### Internal (protected) properties and methods renaming
1097 These properties are not intended for end users
1099 - `id` => `nextMessageId`
1101 These methods are not intended for end users
1103 - `_chooseWorker` => `chooseWorker`
1104 - `_newWorker` => `createWorker`
1105 - `_execute` => `internalExecute`
1106 - `_chooseWorker` => `chooseWorker`
1107 - `_checkAlive` => `checkAlive`
1109 - `_runAsync` => `runAsync`
1111 ## [1.1.0] - 2020-05-21
1115 - ThreadWorker support async functions as option
1116 - Various external library patches
1118 ## [1.0.0] - 2020-01-24
1122 - FixedThreadPool implementation
1123 - DynamicThreadPool implementation
1124 - WorkerThread implementation to improve developer experience
