981 ## [2.2.0] - 2022-01-05
985 - Support only Node.js version 16.x.x for cluster pool: upstream cluster API have changed on that version.
987 ## [2.1.0] - 2021-08-29
991 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
995 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
996 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
997 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
998 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
1000 ## [2.0.2] - 2021-05-12
1004 - Fix `busy` event emission on fixed pool type
1006 ## [2.0.1] - 2021-03-16
1010 - Check if pool options are properly set.
1011 - `busy` event is emitted on all pool types.
1013 ## [2.0.0] - 2021-03-01
1017 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
1019 ### Breaking Changes
1021 - `FullPool` event is now renamed to `busy`.
1022 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1023 _Find more details on our JSDoc._
1025 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1027 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1029 ### Pool options types declaration merge
1031 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1033 #### New `export` strategy
1037 const DynamicThreadPool = require('poolifier/lib/dynamic')
1039 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1042 But you should always prefer just using
1045 const { DynamicThreadPool } = require('poolifier')
1048 #### New type definitions for input data and response
1050 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1051 _This is not a limitation by poolifier but Node.js._
1053 #### Public property replacements
1055 `numWorkers` property is now `numberOfWorkers`
1057 #### Internal (protected) properties and methods renaming
1059 These properties are not intended for end users
1061 - `id` => `nextMessageId`
1063 These methods are not intended for end users
1065 - `_chooseWorker` => `chooseWorker`
1066 - `_newWorker` => `createWorker`
1067 - `_execute` => `internalExecute`
1068 - `_chooseWorker` => `chooseWorker`
1069 - `_checkAlive` => `checkAlive`
1071 - `_runAsync` => `runAsync`
1073 ## [1.1.0] - 2020-05-21
1077 - ThreadWorker support async functions as option
1078 - Various external library patches
1080 ## [1.0.0] - 2020-01-24
1084 - FixedThreadPool implementation
1085 - DynamicThreadPool implementation
1086 - WorkerThread implementation to improve developer experience
