245 ## [2.0.2] - 2021-05-12
249 - Fix `busy` event emission on fixed pool type
251 ## [2.0.1] - 2021-03-16

262 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
266 - `FullPool` event is now renamed to `busy`.
267 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
268 _Find more details on our JSDoc._
270 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
272 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
274 ### Pool options types declaration merge
276 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
278 #### New `export` strategy
282 const DynamicThreadPool = require('poolifier/lib/dynamic')
284 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
287 But you should always prefer just using
290 const { DynamicThreadPool } = require('poolifier')
293 #### New type definitions for input data and response
295 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
296 _This is not a limitation by poolifier but NodeJS._
298 #### Public property replacements
300 `numWorkers` property is now `numberOfWorkers`
302 #### Internal (protected) properties and methods renaming
304 These properties are not intended for end users
306 - `id` => `nextMessageId`
308 These methods are not intended for end users
310 - `_chooseWorker` => `chooseWorker`
311 - `_newWorker` => `createWorker`
312 - `_execute` => `internalExecute`
313 - `_chooseWorker` => `chooseWorker`
314 - `_checkAlive` => `checkAlive`
316 - `_runAsync` => `runAsync`
318 ## [1.1.0] - 2020-05-21
322 - ThreadWorker support async functions as option
323 - Various external library patches
325 ## [1.0.0] - 2020-01-24
329 - FixedThreadPool implementation
330 - DynamicThreadPool implementation
331 - WorkerThread implementation to improve developer experience
