I’m working on WordPress + Bootstrap 4 by customising according to the design. The default style.css loads as:

<link rel='stylesheet' id='wp-bootstrap-starter-style-css'  href='http://localhost/hrone/wp-content/themes/theme_name/style.css?ver=5.2.3' type='text/css' media='all' />

I would like to change the version from 5.2.3 to 5.2.4 or auto change it time base. How do I go about doing this? I have just 1 css file since this is a custom theme.
