Description

In angular 20, mat-button has been changed to matButton. I had 2 questions -

1. Why was it not mentioned in the changelog file? Is it due to this being new and in beta phase or it is stable? Please let me know.

2. And If stable are we going to receive a migration script to change it in the future for updates like these?

Angular material 19 button component code -

  <div class="example-label">Basic</div>
  <div class="example-button-row">
    <button mat-button>Basic</button>
    <button mat-button disabled>Disabled</button>
    <a mat-button href="https://www.google.com/" target="_blank">Link</a>
  </div>
</section>
