This version of the Tag Groups plugin fixes a bug when displaying tag cloud accordions with the parameter “include”.
The feature part of this release is a bit technical: We have introduced endpoints for the WordPress REST API. That means you can retrieve the data of tag groups and tags in a format that can be easily processed by other plugins. This feature is not of relevance for the normal user, but it will increasingly be for the further development.
Please note that currently you can only read data through that API, not modify or delete.
