1464 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1465   _Find more details on our JSDoc._
1466
1467 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1468
1469 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1470
1471 ### Pool options types declaration merge
1472
1473 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1474
1475 #### New `export` strategy
1476
1477 ```js
1478 // Before
1479 const DynamicThreadPool = require('poolifier/lib/dynamic')
1480 // After
1481 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1482 ```
1483
1484 But you should always prefer just using
1485
1486 ```js
1487 const { DynamicThreadPool } = require('poolifier')
1488 ```
1489
1490 #### New type definitions for input data and response
1491
1492 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1493 _This is not a limitation by poolifier but Node.js._
1494
1495 #### Public property replacements
1496
1497 `numWorkers` property is now `numberOfWorkers`
1498
1499 #### Internal (protected) properties and methods renaming
1500
1501 These properties are not intended for end users
1502
1503 - `id` => `nextMessageId`
1504
1505 These methods are not intended for end users
1506
1507 - `_chooseWorker` => `chooseWorker`
1508 - `_newWorker` => `createWorker`
1509 - `_execute` => `internalExecute`
1510 - `_chooseWorker` => `chooseWorker`
