Hi,
Bootstrap is close to being in stable version, version 5.

For designers who work on Bootstrap 4,
with BT5, some parameters change cause there is now RTL features (Right to Left)

So,
all paramters with "left" and "right" become : "start" and "end"
Quote:Examples :
Renamed .dropdown-menu-*-left and .dropdown-menu-*-right to .dropdown-menu-*-start and .dropdown-menu-*-end.
Renamed .carousel-item-left and .carousel-item-right to .carousel-item-start and .carousel-item-end.
Renamed .float-left and .float-right to .float-start and .float-end.
Renamed .border-left and .border-right to .border-start and .border-end.
Renamed .rounded-left and .rounded-right to .rounded-start and .rounded-end.
Renamed .ml-* and .mr-* to .ms-* and .me-*.
Renamed .pl-* and .pr-* to .ps-* and .pe-*.
Renamed .text-left and .text-right to .text-start and .text-end.
Renamed $navbar-brand-margin-right to $navbar-brand-margin-end.

Other things:

Javascript :
Data attributes for all JavaScript plugins are now namespaced to help distinguish Bootstrap functionality from third parties and your own code. For example, we use data-bs-toggle instead of data-toggle.

badge, rounded, breadcrumbs, group buttons, carousel, form...

All is here !

Boostrap V5.0.0 is available now !

And bootwatch with bt5 since today ! (https://bootswatch.com/ )

So,
My first objective is to update xswatch 4 to xswatch5.

I'm starting with the heart of the theme,
After that, I will check the overloaded templates for modules.

I think I will need help for the overloaded templates for modules.

I will come back here with a link on a repository.

great news, thank you
