Aqua Page Builder gets a new facelift today with a bunch of bug fixes and enhancements. Among the highlights is the new flat UI that blends better with the newer version of WordPress. The tabs navigation has also been replaced with a cleaner, quick-select menu.
Other than that, there has not been a major code changes except for some various cleanups. If you’ve been using a your own custom JS/CSS files, I’d suggest that to take a peek at some of the newer commits to make sure there are no conflicts.
For now, this new version will sit on Github for about a week or two to give time for authors to report any bugs before I made it available on WordPress.org shortly afterwards.
