According to this blog post, Bootstrap v3 will not receive security updates anymore and that’s why the Bootstrap 3 download option has been marked as deprecated and will be removed shortly. Once Bootstrap v5 is published, this new version will become our default Starter Theme and Bootstrap v4 will become an optional download.
We’ve removed jQuery as a frontend dependency from our Starter Themes. Please note that jQuery is still needed in the WordPress dashboard (backend) and will be loaded there automatically!
jQuery has been very useful for a while but modern web standards browser support has improved a lot and most JS frameworks started to drop any external dependencies in favor of plain/vanilla JS.
Reducing the loading time of web applications and minimizing HTTP requests is one of the main goals of many developers. And since jQuery is an external library which needs to be downloaded first, avoiding it (if possible) makes a lot of sense.
If your code still depends on jQuery you can activate it in functions.php by adding array( 'jquery' ) in the wp_enqueue_script function where main.js is referenced (See: https://github.com/them-es/themes-starter-bootstrap/blob/v2/functions.php#L480).
Material Components for the web 2.0 has been released recently with new features and bugfixes. The WordPress Material Starter Theme has been tested with the latest version 2.2 and the code base got updated.
The them.es+ plugin has not received much love recently and we decided to put it into EOSL status. This means that the code base will not receive any updates and we can not provide any support anymore. Please note that the plugin will be removed from the WordPress plugin directory and from Github (sooner or later).
Gutenberg became the new default editor in WordPress 5.0 and has superseded any shortcode driven editing experience (which is good by the way!). From now WordPress developers should put their efforts into improving Gutenberg, the future of WordPress.
In this scenario the old-fashioned them.es+ doesn’t fit in.
