61 - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`.
62 _Find more details on our JSDoc._
63
64 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
65
66 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
67
68 ### Pool options types declaration merge
69
70 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
71
72 #### New `export` strategy
73
74 ```js
75 // Before
76 const DynamicThreadPool = require('poolifier/lib/dynamic')
77 // After
78 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
79 ```
80
81 But you should always prefer just using
82
83 ```js
84 const { DynamicThreadPool } = require('poolifier')
85 ```
86
87 #### New type definitions for input data and response
88
89 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
90 _This is not a limitation by poolifier but NodeJS._
91
92 #### Public property replacements
93
94 `numWorkers` property is now `numberOfWorkers`
95
96 #### Internal (protected) properties and methods renaming
97
98 These properties are not intended for end users
99
100 - `id` => `nextMessageId`
101
102 These methods are not intended for end users
103
104 - `_chooseWorker` => `chooseWorker`
105 - `_newWorker` => `createWorker`
106 - `_execute` => `internalExecute`
107 - `_chooseWorker` => `chooseWorker`
108 - `_checkAlive` => `checkAlive`
