Hi community, as [Nextcloud 30 (Hub 9)](https://help.nextcloud.com/tag/nc30) has landed [(see release intro)](https://www.youtube.com/watch?v=EnT_OVfE4nw) it’s time to bundle frequent issues into a **WIKI post** (everybody is welcome to add content) to help users to find solutions for frequent issues after update to NC30. This should avoid flooding forum with similar topics and help others identify and solve known issues. > **readme documented changes** > > from: [Upgrade to Nextcloud 30 — Nextcloud latest Administration Manual latest documentation](https://docs.nextcloud.com/server/latest/admin_manual/release_notes/upgrade_to_30.html) > > ### System requirements > > - PHP 8.1 is now deprecated but still supported. > - PHP 8.0 is no longer supported. > - PostgreSQL 9.4 is no longer supported. > - MariaDB 10.3 and 10.5 are no longer supported. > - Make sure that your web server is serving files with the `webp` extension (WebP images) > > ### Nextcloud configuration > > Changes to the available options in `config.php`. > > - The option `blacklisted_files` is now deprecated and replaced with `forbidden_filenames` > - The option `forbidden_chars` is now deprecated and replaced with `forbidden_filename_characters` > - The option `forbidden_filename_basenames` was added to allow bocking files with specific basenames (the filename without extension (before the first dot)) > - The option `forbidden_filename_extensions` was added to allow blocking extensions from being used on filenames > > ### Previews for PDF files with Imaginary > > The preview provider `OC\Preview\Imaginary` is no longer generating previews for PDF files.
