+`setTimeout`, `setInterval` and related clear functions have been part of the JavaScript ecosystem, probably for as long as it has existed.
 
-In the previous releases we stabilized and made them available through `k6/timers` module. While the module isn't going anywhere and might get more identifiers, `setTimeout` is usually used without importing it. For this reason it is now globally available along `clearTimeot`, `setInterval` and `clearInterval`.

 No code needs to be changed, but you no longer need to import `k6/timers` to use this functionality.

 ## Future plans
 
 ### Use Blob as default value for WebSocket.binaryType 
 
-As the changes in documentation mention, [`binaryType`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket/binaryType) was by deafult set to `arraybuffer`, now instead it is by default `""` (empty string).

 In a not so remote future, instead, we expect to introduce and use Blob object.
 
 ### WebCrypto graduation
 
-WebCrypto got more features in the current release, and we expect to continute its expansion in the next iterations. Reaching a wider coverage will push WebCrypto module to being graduated as a stable module.
