  83 ### Breaking Changes
  84

  88
  89 ### Added
  90
  91 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
  92
  93 ### Breaking Changes
  94
  95 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
  96 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
  97 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
  98 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
  99
 100 ## [2.0.2] - 2021-05-12
 101
 102 ### Bug fixes
 103
 104 - Fix `busy` event emission on fixed pool type
 105
 106 ## [2.0.1] - 2021-03-16
 107
 108 ### Bug fixes
 109
 110 - Check if pool options are properly set.
 111 - `busy` event is emitted on all pool types.
 112
 113 ## [2.0.0] - 2021-03-01
 114
 115 ### Bug fixes
 116
 117 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
 118
 119 ### Breaking Changes
 120
 121 - `FullPool` event is now renamed to `busy`.
 122 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
 123   _Find more details on our JSDoc._
 124
 125 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
 126
 127 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
 128
 129 ### Pool options types declaration merge
 130
 131 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
 132
 133 #### New `export` strategy
 134
 135 ```js
 136 // Before
 137 const DynamicThreadPool = require('poolifier/lib/dynamic')
 138 // After
 139 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
 140 ```
 141
 142 But you should always prefer just using
 143
 144 ```js
 145 const { DynamicThreadPool } = require('poolifier')
 146 ```
 147
 148 #### New type definitions for input data and response
 149
 150 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
 151 _This is not a limitation by poolifier but NodeJS._
 152
 153 #### Public property replacements
 154
 155 `numWorkers` property is now `numberOfWorkers`
 156
 157 #### Internal (protected) properties and methods renaming
 158
 159 These properties are not intended for end users
 160
 161 - `id` => `nextMessageId`
 162
 163 These methods are not intended for end users
 164
 165 - `_chooseWorker` => `chooseWorker`
 166 - `_newWorker` => `createWorker`
 167 - `_execute` => `internalExecute`
 168 - `_chooseWorker` => `chooseWorker`
 169 - `_checkAlive` => `checkAlive`
 170 - `_run` => `run`
 171 - `_runAsync` => `runAsync`
 172
 173 ## [1.1.0] - 2020-05-21
 174
 175 ### Added
 176
 177 - ThreadWorker support async functions as option
 178 - Various external library patches
 179
 180 ## [1.0.0] - 2020-01-24
 181
 182 ### Added
 183
 184 - FixedThreadPool implementation
 185 - DynamicThreadPool implementation
 186 - WorkerThread implementation to improve developer experience
