Different Joomla! versions

Hi,

Thanks for contacting us here about this extension.

When upgrading a website from Joomla! 3 to 4 to 5, several things will occur:

1. Version Compatibility: Ensure that each extension and template used on your site is compatible with the new version. JoomUnited's extensions, for instance, are mentioned to be compatible with Joomla 3, 4, and 5, but it's always wise to verify specific components.

2. Database Adjustments: The upgrade might involve changes in the database schemas. Joomla's core upgrade process typically takes care of these adjustments, but backups are essential.

3. Template Updates: Some templates designed for Joomla 3 might not work seamlessly with Joomla 4 or 5. Ensure your template provider offers versions compatible with the latest Joomla releases.

Regarding the "J5 (B/C plugin)" indicated in the Joomla Extension Directory (JED), it's plausible that "B/C" stands for "backwards-compatible". This implies that the plugin is designed to work with previous versions of Joomla as well as Joomla 5. While such plugins offer the convenience of broad compatibility, they might not fully leverage new features or optimizations available in the latest Joomla version. It's essential to read the plugin's documentation for any specific limitations.

As for the plans to provide different types of extensions for Joomla 5, the current strategy as per the documents seems to be ensuring that existing extensions are updated and compatible with all the latest versions up to Joomla 5.
