It has been some time since Bootstrap moved forward to the next version which is 5, however it is still in beta at time of writing this (9th Jan, 2021). This also means that Bootstrap has put it's version 4 to latest stable version which as of now is Bootstrap 4.5.0.
Since all our current templates were built with Bootstrap 4, we have boosted their version to Bootstrap 4.5.0. You can download the new version from our site or via your Gumroad account where you purchased the template. You can access the docs for Bootstrap 4.5.0 if you need it.
If you are already using the earlier version of our template, it is not needed to update to the latest version unless you want to use any of the features introduced in Bootstrap 4.5.0.
Going forward, we will be building new templates with the Bootstrap 5 version. There are many new changes in this new release and you can read all about the changes in my article on Bootstrap 5 vs Bootstrap 4. Largely, this involves breaking changes hence we are not updating the current templates to Bootstrap 5 as of now. However this may change in future.
Note that Bootstrap 5 has removed support for IE 10 and 11, hence we will be following similar suit for our new templates.
You can follow us on @templateflip for staying up-to-date with latest updates.
Happy New Year!
