1510 ### Breaking Changes
1512 - `FullPool` event is now renamed to `busy`.
1513 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
1514 _Find more details on our JSDoc._
1516 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
1518 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
1520 ### Pool options types declaration merge
1522 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
1524 #### New `export` strategy
1528 const DynamicThreadPool = require('poolifier/lib/dynamic')
1530 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
1533 But you should always prefer just using
1536 const { DynamicThreadPool } = require('poolifier')
1539 #### New type definitions for input data and response
1541 For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
1542 _This is not a limitation by poolifier but Node.js._
1544 #### Public property replacements
1546 `numWorkers` property is now `numberOfWorkers`
1548 #### Internal (protected) properties and methods renaming
1550 These properties are not intended for end users
1552 - `id` => `nextMessageId`
1554 These methods are not intended for end users
1556 - `_chooseWorker` => `chooseWorker`
1557 - `_newWorker` => `createWorker`
1558 - `_execute` => `internalExecute`
1559 - `_chooseWorker` => `chooseWorker`
1560 - `_checkAlive` => `checkAlive`
1562 - `_runAsync` => `runAsync`
1564 ## [1.1.0] - 2020-05-21

1569 - Various external library patches
1571 ## [1.0.0] - 2020-01-24

1576 - DynamicThreadPool implementation
1577 - WorkerThread implementation to improve developer experience
