Bootstrap 5 provides components like in previous versions, however some changes have been made like:

• jQuery is out

• Some components are now import available only, like tooltips and popovers (due to performance)

• Data selectors went from "data-toggle" to "data-bs-toggle" to try and not intrude into any custom selector you wanna make.

• Better utilities API and override for CSS variables. I mean changing scaffold values from site to site isn't abnormal.

• Supports CSS grid better as well.

There are a few things that got also thrown out, like:

• Jumbotron is gone (in all reality that wasn't something difficult to make in itself)

• Dropped support for IE < 10

• Some global classes got renamed for standardization clarification: margin-left was ml, now it's ms as margin-start for example.

• Icons are now bootstrap native, and not font-awesome (not sure if this can have a visual impact)

Obviously there are many more differences between them but these are the more glaring ones FOR ME. Also note that differences do not specifically denote to syntax, some of them can simply change the design/visuals but act the same.

Bootstrap 5 is in itself a (mini?)framework. If you are looking for a template based on it then I'm not sure that they are that much available since it's fairly new-ish and dev's didn't really have time to build something upon it and shell it in masse.

However, if your team can integrate bootstrap 5 in projects and build boilerplate components off them when it's a repeating component, a template shouldn't realistically be necessary. It's technically a safer method this way since you have more control over you template(s)'s designs... but the downside is that it can, and most likely will, take a good chunk of time in originally making it.
