218
219 - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute.
220 - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`.
221 - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`.
222 - `AbstractWorker` class cannot be instantiated without specifying the `mainWorker` argument referencing the main worker.
223
224 ## [2.0.2] - 2021-05-12
225
226 ### Bug fixes
227
228 - Fix `busy` event emission on fixed pool type
229
230 ## [2.0.1] - 2021-03-16
231
232 ### Bug fixes
233
234 - Check if pool options are properly set.
235 - `busy` event is emitted on all pool types.
236
237 ## [2.0.0] - 2021-03-01
238
239 ### Bug fixes
240
241 - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).
242
243 ### Breaking Changes
244
245 - `FullPool` event is now renamed to `busy`.
246 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
247 _Find more details on our JSDoc._
248
249 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
250
251 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
252
253 ### Pool options types declaration merge
254
255 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
256
257 #### New `export` strategy
258
259 ```js
260 // Before
261 const DynamicThreadPool = require('poolifier/lib/dynamic')
262 // After
263 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
264 ```
265
266 But you should always prefer just using
267
268 ```js
269 const { DynamicThreadPool } = require('poolifier')
270 ```
271
272 #### New type definitions for input data and response
273
274 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
275 _This is not a limitation by poolifier but NodeJS._
276
277 #### Public property replacements
278
279 `numWorkers` property is now `numberOfWorkers`
280
281 #### Internal (protected) properties and methods renaming
282
283 These properties are not intended for end users
284
285 - `id` => `nextMessageId`
286
287 These methods are not intended for end users
288
289 - `_chooseWorker` => `chooseWorker`
290 - `_newWorker` => `createWorker`
291 - `_execute` => `internalExecute`
292 - `_chooseWorker` => `chooseWorker`
293 - `_checkAlive` => `checkAlive`
294 - `_run` => `run`
295 - `_runAsync` => `runAsync`
296
297 ## [1.1.0] - 2020-05-21

301 - ThreadWorker support async functions as option
302 - Various external library patches
303
304 ## [1.0.0] - 2020-01-24
