GD Topic Prefix Pro version 3.7 (and 3.8) are smaller scope releases that include the latest shared code library, various updates, and fixes and add a license code panel in the plugin settings and plugin dashboard notice about license status.
Version 3.7 has been updated with the latest Dev4Press Library, which introduced some styling changes for the admin panel and, more importantly, fixes for issues with some settings types handling that affected the GD Topic Prefix plugin. The plugin now has the License code panel in Settings, where you need to add your license code. It is important to know that the license code, while it is required, is not enforced at this time. Once the GD Topic Prefix Pro 4.0 is released, the license code will be mandatory!

Version 3.8 also adds new group settings that involve the permissions related to topic author, changes to the handling of the prefixes saving and displaying, and numerous fixes for some edge cases where multiple groups are used with very different set of permissions.
The plugin is tested with the latest WordPress versions and the latest PHP versions, including PHP 8.3, and no issues have been found. There are various minor tweaks and changes to the plugin code, including code standards changes.
Let me know if you find any issues with this version or if you have any new suggestions by posting in plugin support forums. Right now, there are a few smaller features in the works for the next 3.9 and 4.0 versions, which are planned for later this year.
