Why is the stable-release composer sticker not being updated on github?

Question

GitHub

There is a project on github, with various stickers designed by README (link at the end).
I'm doing the first release of 1.0.0, the stable sticker (which is in the README) shows the correct version.
I'm pushing a couple of commits.
I'm making the next release 1.0.1. The stable sticker still shows the previous version. After this release, I made a commit just in case - it did not help.
Although, composer says everything is ok:

$ composer show comm1x/vacuum | grep versions
versions : dev-master, 1.0.1, 1.0.0

And GitHub in releases/latest correctly shows the latest release 1.0.1.
What are the options, who knows how it is treated?
The project itself is on GitHub: https://github.com/comm1x/vacuum
Packagist: https://packagist.org/packages/comm1x/vacuum

Answer 1

It was necessary to press Force Update in packagist.
