The official version of Bootstrap 4.0.0 has now been released, and the updated content has not changed significantly from the previous beta, but has made some key improvements and solved some tricky mistakes.
A new example
Almost every example has been significantly modified by a stable V4 version, with some obsolete examples removed, new examples added, and other examples completely changed.
Of course, there are still known issues in the stable version that have not been repaired, and are expected to be repaired when the next iteration is updated, such as Input groups, validation, and rounded corners.
On the subject, Bootstrap's theme will be significantly updated this year, and officials say 10 new themes will be launched. The current goal is to launch the first quarter of the theme is based on Bootstrap 4 (there is no V3 version of).
