286
287 ## [2.0.1] - 2021-03-16

299
300 ### Breaking Changes
301
302 - `FullPool` event is now renamed to `busy`.
303 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
304 _Find more details on our JSDoc._
305
306 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
307
308 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
309
310 ### Pool options types declaration merge
311
312 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
313
314 #### New `export` strategy
315
316 ```js
317 // Before
318 const DynamicThreadPool = require('poolifier/lib/dynamic')
319 // After
320 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
321 ```
322
323 But you should always prefer just using
324
325 ```js
326 const { DynamicThreadPool } = require('poolifier')
327 ```
328
329 #### New type definitions for input data and response
330
331 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
332 _This is not a limitation by poolifier but NodeJS._
333
334 #### Public property replacements
335
336 `numWorkers` property is now `numberOfWorkers`
337
338 #### Internal (protected) properties and methods renaming
339
340 These properties are not intended for end users
341
342 - `id` => `nextMessageId`
343
344 These methods are not intended for end users
345
346 - `_chooseWorker` => `chooseWorker`
347 - `_newWorker` => `createWorker`
348 - `_execute` => `internalExecute`
349 - `_chooseWorker` => `chooseWorker`
350 - `_checkAlive` => `checkAlive`
351 - `_run` => `run`
352 - `_runAsync` => `runAsync`
353
354 ## [1.1.0] - 2020-05-21
355
356 ### Added
357
358 - ThreadWorker support async functions as option
359 - Various external library patches
360
361 ## [1.0.0] - 2020-01-24
362
363 ### Added
364
365 - FixedThreadPool implementation
366 - DynamicThreadPool implementation
367 - WorkerThread implementation to improve developer experience
