871
872### Breaking Changes
873
874- `FullPool` event is now renamed to `busy`.
875- `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
876 _Find more details on our JSDoc._
877
878- `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
879
880- We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
881
882### Pool options types declaration merge
883
884`FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
885
886#### New `export` strategy
887
888```js
889// Before
890const DynamicThreadPool = require('poolifier/lib/dynamic')
891// After
892const { DynamicThreadPool } = require('poolifier/lib/dynamic')
893```
894
895But you should always prefer just using
896
897```js
898const { DynamicThreadPool } = require('poolifier')
899```
900
901#### New type definitions for input data and response
902
903For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
904_This is not a limitation by poolifier but Node.js._
905
906#### Public property replacements
907
908`numWorkers` property is now `numberOfWorkers`
909
910#### Internal (protected) properties and methods renaming
911
912These properties are not intended for end users
913
914- `id` => `nextMessageId`
915
916These methods are not intended for end users
917
918- `_chooseWorker` => `chooseWorker`
919- `_newWorker` => `createWorker`
920- `_execute` => `internalExecute`
921- `_chooseWorker` => `chooseWorker`
922- `_checkAlive` => `checkAlive`
923- `_run` => `run`
