GD Content Tools Pro 5.3.2 is the minor release that includes several bug fixes, updated libraries, various updates and support for the upcoming WordPress Gutenberg editor (currently in development).
If you want to test and use Gutenberg editor (still in development), you will be happy to hear that GD Content Tools Pro metaboxes support Gutenberg editor (tested with latest Gutenberg 2.4). If something changes with future Gutenberg versions, it might break the GD Content Tools Pro, but, report any issues, and I will try to fix them as soon as possible.
Other changes in this version include updated shared code library, and several JavaScript libraries plugin uses. There are various styling updates and changes, and fixes for 2 recently reported bugs: problem with the meta field for the Fontawesome Icon and rendering of the list based fields.
If you notice any more issues, please report them in the support forum.
