1510 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.

1512
1513 ## [2.0.2] - 2021-05-12
1514
1515 ### Bug fixes
1516
1517 - Fix `busy` event emission on fixed pool type
1518
1519 ## [2.0.1] - 2021-03-16
1520
1521 ### Bug fixes
1522
1523 - Check if pool options are properly set.
1524 - `busy` event is emitted on all pool types.
1525
1526 ## [2.0.0] - 2021-03-01

1531
1532 ### Breaking Changes
1533
1534 - `FullPool` event is now renamed to `busy`.
1535 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1536   _Find more details on our JSDoc._
1537
1538 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1539
1540 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1541
1542 ### Pool options types declaration merge
1543
1544 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1545
1546 #### New `export` strategy
1547
1548 ```js
1549 // Before
1550 const DynamicThreadPool = require('poolifier/lib/dynamic')
1551 // After
1552 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1553 ```
1554
1555 But you should always prefer just using
1556
1557 ```js
1558 const { DynamicThreadPool } = require('poolifier')
1559 ```
1560
1561 #### New type definitions for input data and response
1562
1563 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1564 _This is not a limitation by poolifier but Node.js._
1565
1566 #### Public property replacements
1567
1568 `numWorkers` property is now `numberOfWorkers`
1569
1570 #### Internal (protected) properties and methods renaming
1571
1572 These properties are not intended for end users
1573
1574 - `id` => `nextMessageId`
1575
1576 These methods are not intended for end users
1577
1578 - `_chooseWorker` => `chooseWorker`
1579 - `_newWorker` => `createWorker`
1580 - `_execute` => `internalExecute`
1581 - `_chooseWorker` => `chooseWorker`
1582 - `_checkAlive` => `checkAlive`
1583 - `_run` => `run`
1584 - `_runAsync` => `runAsync`
1585
1586 ## [1.1.0] - 2020-05-21
1587
1588 ### Added
1589
1590 - ThreadWorker support async functions as option
1591 - Various external library patches
1592
1593 ## [1.0.0] - 2020-01-24
1594
1595 ### Added
1596
1597 - FixedThreadPool implementation
1598 - DynamicThreadPool implementation
1599 - WorkerThread implementation to improve developer experience
