241 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
242 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
243 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
244
245 ## [2.0.2] - 2021-05-12
246

248
249 - Fix `busy` event emission on fixed pool type
250
251 ## [2.0.1] - 2021-03-16
252
253 ### Bug fixes
254
255 - Check if pool options are properly set.

257
258 ## [2.0.0] - 2021-03-01
259
260 ### Bug fixes
261
262 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
263
264 ### Breaking Changes
265
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._
269
270 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
271
272 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
273
274 ### Pool options types declaration merge
275
276 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
277
278 #### New `export` strategy
279
280 ```js
281 // Before
282 const DynamicThreadPool = require('poolifier/lib/dynamic')
283 // After
284 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
285 ```
286
287 But you should always prefer just using
288
289 ```js
290 const { DynamicThreadPool } = require('poolifier')
291 ```
292
293 #### New type definitions for input data and response
294
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._
297
298 #### Public property replacements
299
300 `numWorkers` property is now `numberOfWorkers`
301
302 #### Internal (protected) properties and methods renaming
303
304 These properties are not intended for end users
305
306 - `id` => `nextMessageId`
307
308 These methods are not intended for end users
309
310 - `_chooseWorker` => `chooseWorker`
311 - `_newWorker` => `createWorker`
312 - `_execute` => `internalExecute`
313 - `_chooseWorker` => `chooseWorker`
314 - `_checkAlive` => `checkAlive`
315 - `_run` => `run`
316 - `_runAsync` => `runAsync`
317
318 ## [1.1.0] - 2020-05-21

320 ### Added
321
322 - ThreadWorker support async functions as option
323 - Various external library patches
324
325 ## [1.0.0] - 2020-01-24

330 - DynamicThreadPool implementation
331 - WorkerThread implementation to improve developer experience
