981 ## [2.2.2] - 2022-10-09
985 - Fixed `README.md` file.
987 ## [2.2.1] - 2022-10-08
991 - Dynamic worker choice strategy change at runtime.
993 ## [2.2.0] - 2022-01-05
997 - Support only Node.js version 16.x.x for cluster pool: upstream cluster API have changed on that version.
999 ## [2.1.0] - 2021-08-29
1003 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
1005 ### Breaking Changes
1007 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
1008 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
1009 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
1010 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
1012 ## [2.0.2] - 2021-05-12
1016 - Fix `busy` event emission on fixed pool type
1018 ## [2.0.1] - 2021-03-16
1022 - Check if pool options are properly set.
1023 - `busy` event is emitted on all pool types.
1025 ## [2.0.0] - 2021-03-01
1029 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
1031 ### Breaking Changes
1033 - `FullPool` event is now renamed to `busy`.
1034 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1035 _Find more details on our JSDoc._
1037 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1039 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1041 ### Pool options types declaration merge
1043 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1045 #### New `export` strategy
1049 const DynamicThreadPool = require('poolifier/lib/dynamic')
1051 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1054 But you should always prefer just using
1057 const { DynamicThreadPool } = require('poolifier')
1060 #### New type definitions for input data and response
1062 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1063 _This is not a limitation by poolifier but Node.js._
1065 #### Public property replacements
1067 `numWorkers` property is now `numberOfWorkers`
1069 #### Internal (protected) properties and methods renaming
1071 These properties are not intended for end users
1073 - `id` => `nextMessageId`
1075 These methods are not intended for end users
1077 - `_chooseWorker` => `chooseWorker`
1078 - `_newWorker` => `createWorker`
1079 - `_execute` => `internalExecute`
1080 - `_chooseWorker` => `chooseWorker`
1081 - `_checkAlive` => `checkAlive`
1083 - `_runAsync` => `runAsync`
1085 ## [1.1.0] - 2020-05-21
1089 - ThreadWorker support async functions as option
1090 - Various external library patches
1092 ## [1.0.0] - 2020-01-24
1096 - FixedThreadPool implementation
1097 - DynamicThreadPool implementation
1098 - WorkerThread implementation to improve developer experience
