Tag Clouds: You can now use the placeholder {count} for the "prepend" and "append" parameters. It will be replaced by the post count for each tag.
Dynamic Post Filter: New parameter "open" to determine groups that should be initially open.
Instead of shortcodes you can now use Gutenberg blocks. This requires the installation of the Gutenberg plugin.

Taxonomies are now shown in the settings with their "human-readable" names.
The HTML structure around tags was slightly changed. Please check if you customized anything.
The default class for the table tag cloud (if no table_class is given) is now "tag-groups-cloud-table" to avoid collisions. For the combined tag cloud it is "tag-groups-cloud-combined" for the enclosing div.
