About six hours ago, I changed permalink after a post has been published on June 25th, 2008 at 5:23 pm) and indexed by Google. Permalink changed from https://www.webminimalist.com/new-born.htm to https://www.webminimalist.com/static-page-and-a-wordpress-blog.htm.

Below is screenshot of pages indexed by Google today:

When I checked it on Google search, the permalink is still the old one. And when I clicked on the old permalink, it is redirect to the new one.
