Current behavior

Due to upgrade of @mdi/angular-material dependency #1706 some icon names changed and it breaks applications.

ie: github-circle has been renamed to github Templarian/MaterialDesign#4823

Expected behavior

This change should be communicated with teams using Stark 10 and should be documented somewhere.

The full list of changes is available on Templarian/MaterialDesign#4901

What is the motivation / use case for changing the behavior?

Communication / Fix Showcase

@SuperITMan another solution would be to simply revert this change and stick to the 4.9.xxx version cause this was just merged in Stark after the 10.0.0 release.

For me both solutions are fine

[SuperITMan]

@christophercr I thought this change was included in the release 10.0.0.
Since it is not the case, I think you're right. We should revert this change and maybe keep it for the next major release 😊 (Angular 8).
Like this, we can add the necessary information in the CHANGELOG

Btw, after investing a bit more, I found the official CHANGELOG: https://dev.materialdesignicons.com/changelog
Good to know for the next updates
