979 ## [2.0.1] - 2021-03-16
983 - Check if pool options are properly set.
984 - `busy` event is emitted on all pool types.
986 ## [2.0.0] - 2021-03-01
990 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
994 - `FullPool` event is now renamed to `busy`.
995 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
996 _Find more details on our JSDoc._
998 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1000 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1002 ### Pool options types declaration merge
1004 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1006 #### New `export` strategy
1010 const DynamicThreadPool = require('poolifier/lib/dynamic')
1012 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1015 But you should always prefer just using
1018 const { DynamicThreadPool } = require('poolifier')
1021 #### New type definitions for input data and response
1023 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1024 _This is not a limitation by poolifier but Node.js._
1026 #### Public property replacements
1028 `numWorkers` property is now `numberOfWorkers`
1030 #### Internal (protected) properties and methods renaming
1032 These properties are not intended for end users
1034 - `id` => `nextMessageId`
1036 These methods are not intended for end users
1038 - `_chooseWorker` => `chooseWorker`
1039 - `_newWorker` => `createWorker`
1040 - `_execute` => `internalExecute`
1041 - `_chooseWorker` => `chooseWorker`
1042 - `_checkAlive` => `checkAlive`
1044 - `_runAsync` => `runAsync`
1046 ## [1.1.0] - 2020-05-21

1051 - Various external library patches
1053 ## [1.0.0] - 2020-01-24
1057 - FixedThreadPool implementation
1058 - DynamicThreadPool implementation
1059 - WorkerThread implementation to improve developer experience
