d8w3css/templates/layout/page.tpl.twig was changed and match height was disabled.
If you created a sub theme and copied page.tpl to your sub theme, Match height it will always be enabled.
I removed the match height classes from the page and made them optional. You can enable match height in the theme settings your-site-url/admin/appearance/settings/drupal8_w3css_theme and expand "Disable/Enable Match Height" They are disabled by default now.

Issue #2910124: Add support for mapping Plan code and name
Headroom.js version 8.x-1.0-beta2 restores functionality to the module. The 3rd party library no longer has a dist folder so a packaged version of it from unpkg.com is recommended instead and paths had to change.
