978 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
980 ## [2.0.2] - 2021-05-12
984 - Fix `busy` event emission on fixed pool type
986 ## [2.0.1] - 2021-03-16
990 - Check if pool options are properly set.
991 - `busy` event is emitted on all pool types.
993 ## [2.0.0] - 2021-03-01
997 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
1001 - `FullPool` event is now renamed to `busy`.
1002 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1003 _Find more details on our JSDoc._
1005 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1007 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1009 ### Pool options types declaration merge
1011 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1013 #### New `export` strategy
1017 const DynamicThreadPool = require('poolifier/lib/dynamic')
1019 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1022 But you should always prefer just using
1025 const { DynamicThreadPool } = require('poolifier')
1028 #### New type definitions for input data and response
1030 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1031 _This is not a limitation by poolifier but Node.js._
1033 #### Public property replacements
1035 `numWorkers` property is now `numberOfWorkers`
1037 #### Internal (protected) properties and methods renaming
1039 These properties are not intended for end users
1041 - `id` => `nextMessageId`
1043 These methods are not intended for end users
1045 - `_chooseWorker` => `chooseWorker`
1046 - `_newWorker` => `createWorker`
1047 - `_execute` => `internalExecute`
1048 - `_chooseWorker` => `chooseWorker`
1049 - `_checkAlive` => `checkAlive`
1051 - `_runAsync` => `runAsync`
1053 ## [1.1.0] - 2020-05-21
1057 - ThreadWorker support async functions as option
1058 - Various external library patches
1060 ## [1.0.0] - 2020-01-24
1064 - FixedThreadPool implementation
1065 - DynamicThreadPool implementation
1066 - WorkerThread implementation to improve developer experience
