 786
 787 ## [2.0.1] - 2021-03-16
 788

 793
 794 ## [2.0.0] - 2021-03-01

 797
 798 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
 799
 800 ### Breaking Changes
 801
 802 - `FullPool` event is now renamed to `busy`.
 803 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
 804   _Find more details on our JSDoc._
 805
 806 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
 807
 808 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
 809
 810 ### Pool options types declaration merge
 811
 812 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
 813
 814 #### New `export` strategy
 815
 816 ```js
 817 // Before
 818 const DynamicThreadPool = require('poolifier/lib/dynamic')
 819 // After
 820 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
 821 ```
 822
 823 But you should always prefer just using
 824
 825 ```js
 826 const { DynamicThreadPool } = require('poolifier')
 827 ```
 828
 829 #### New type definitions for input data and response
 830
 831 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
 832 _This is not a limitation by poolifier but Node.js._
 833
 834 #### Public property replacements
 835
 836 `numWorkers` property is now `numberOfWorkers`
 837
 838 #### Internal (protected) properties and methods renaming
 839
 840 These properties are not intended for end users
 841
 842 - `id` => `nextMessageId`
 843
 844 These methods are not intended for end users
 845
 846 - `_chooseWorker` => `chooseWorker`
 847 - `_newWorker` => `createWorker`
 848 - `_execute` => `internalExecute`
 849 - `_chooseWorker` => `chooseWorker`
 850 - `_checkAlive` => `checkAlive`
 851 - `_run` => `run`
 852 - `_runAsync` => `runAsync`
 853
 854 ## [1.1.0] - 2020-05-21
 855
 856 ### Added
 857
 858 - ThreadWorker support async functions as option
 859 - Various external library patches
 860
 861 ## [1.0.0] - 2020-01-24

 866 - DynamicThreadPool implementation
 867 - WorkerThread implementation to improve developer experience
