This version includes only the english language files. All other language php files should be updated to ini files (this will happen in the next release)
This version includes only the modern template, since this is the only one that doesn't produce any errors. The other templates should be updated in the next release.
This version should be able to update from joomlacomment 4.0. But please be careful. Make a backup first, don't test on production sites! Once you update to 4.1 you will not be able to return to 4.0 without manually executing sql queries in the database.
What do I want to achieve with this version. The backend and the frontend have nothing to do with 4.0! The code is structured, organized better and cleaner! Functions that were not used and were in the package only for legacy purposes are removed from the package.
