1220 ## [2.2.0] - 2022-01-05
1222 ### Breaking Changes

1226 ## [2.1.0] - 2021-08-29
1230 - Add an optional pool option `messageHandler` to `PoolOptions<Worker>` for registering a message handler callback on each worker.
1232 ### Breaking Changes
1234 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
1235 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
1236 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.

1258 ### Breaking Changes
1260 - `FullPool` event is now renamed to `busy`.
1261 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1262 _Find more details on our JSDoc._
1264 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1266 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1268 ### Pool options types declaration merge
1270 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1272 #### New `export` strategy
1276 const DynamicThreadPool = require('poolifier/lib/dynamic')
1278 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1281 But you should always prefer just using
1284 const { DynamicThreadPool } = require('poolifier')
1287 #### New type definitions for input data and response
1289 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1290 _This is not a limitation by poolifier but Node.js._
1292 #### Public property replacements
1294 `numWorkers` property is now `numberOfWorkers`
1296 #### Internal (protected) properties and methods renaming
1298 These properties are not intended for end users
1300 - `id` => `nextMessageId`
1302 These methods are not intended for end users
1304 - `_chooseWorker` => `chooseWorker`
1305 - `_newWorker` => `createWorker`
1306 - `_execute` => `internalExecute`
1307 - `_chooseWorker` => `chooseWorker`
1308 - `_checkAlive` => `checkAlive`
1310 - `_runAsync` => `runAsync`
1312 ## [1.1.0] - 2020-05-21

1317 - Various external library patches
1319 ## [1.0.0] - 2020-01-24

1324 - DynamicThreadPool implementation
1325 - WorkerThread implementation to improve developer experience
