The Mail settings wording was updated to better describe what the External Email Server option does. This helps users understand that disabling the option does not stop external email servers from being used, reducing confusion in configuration.

The wording was "Use" but when you disable it the option, they don't
stop being used.

This fixes an error that could appear when users clicked an input in the website editor's left panel. The change removes an outdated event hookup so editing controls behave reliably again.

I removed a handler without removing the event binding by mistake...

This fix removes an unnecessary style that caused color icons in the website editor to appear inconsistently. Users choosing colors in the editor now see clearer, uniform square icons, making the editing experience more predictable.
