DNN Community Forums 09.05.00 is now available!

Download DNN Community Forums 09.05.00

This release greatly enhances the search features in DNN Community Forums. Specifically, we are now using DNN Search (Lucene) to perform searches. This removes the need to install SQL Server full-text search for "better" results, which wasn't compatible with Azure.

We also fixed and enhanced a few things.

If you encounter issues, or have questions, please open an issue on GitHub.
