BREAKING CHANGE: We have reduced the size of Popper.js removing the Popper.Utils methods from the basic bundle. If you need them, you can still import popper-utils.js before popper.js and they will be available again. But we suggest to directly use the PopperUtils object exported by popper-utils.js because we may deprecate Popper.Utils in the future major versions of Popper.js.
We haven't followed semver in this case because Popper.Utils weren't so much used and we support a drop-in replacement that makes it super easy to upgrade.
Along with this change, we reduced the size of the bundle a bit more cleaning some code and we refactored our build process to make it easier to maintain and run.
We also released Tooltip.js v1.1.0 to address the breaking change mentioned previously.
