  56   _Find more details on our JSDoc._
  57
  58 - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed.
  59
  60 - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.
  61
  62 ### Pool options types declaration merge
  63
  64 `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`.
  65
  66 #### New `export` strategy
  67
  68 ```js
  69 // Before
  70 const DynamicThreadPool = require('poolifier/lib/dynamic')
  71 // After
  72 const { DynamicThreadPool } = require('poolifier/lib/dynamic')
  73 ```
  74
  75 But you should always prefer just using
  76
  77 ```js
  78 const { DynamicThreadPool } = require('poolifier')
  79 ```
  80
  81 #### New type definitions for input data and response
  82
  83 For cluster worker and worker-thread pools, you can now only send and receive serializable data.
  84 _This is not a limitation by poolifier but NodeJS._
  85
  86 #### Public property replacements
  87
  88 `numWorkers` property is now `numberOfWorkers`
  89
  90 #### Internal (protected) properties and methods renaming
  91
  92 These properties are not intended for end users
  93
  94 - `id` => `nextMessageId`
  95
  96 These methods are not intended for end users
  97
  98 - `_chooseWorker` => `chooseWorker`
  99 - `_newWorker` => `createWorker`
 100 - `_execute` => `internalExecute`
 101 - `_chooseWorker` => `chooseWorker`
 102 - `_checkAlive` => `checkAlive`
