missing release tags > 2.2.7

[MathieuDerelle]

I'm using your gem (version 3.2.2) but this repo has no release tag above 2.2.7

How to know which code is released ?

Is this gem always including bootstrap3 ? (and the version of gem is just adjusting for ruby/rails version ?)
(in which case, it would have been easier to have it the name, ex: twitter-bootstrap3-rails)

Is this gem following the version of bootstrap itself ?

How to know which version of bootstrap is used ?
