# Upgrade to Nextcloud 30

## 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.

## Web server configuration

Make sure that your web server is serving files with the `webp` extension (WebP images) correctly as static assets. This is included in the shipped `.htaccess` file but if you use another web server or custom configuration you need to check this manually.

## 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. Add the new preview provider `OC\Preview\ImaginaryPDF` to `enabledPreviewProviders` to enable preview generation with Imaginary for PDF files.

## Automated clean-up of app password

Nextcloud 30 will clean-up unused app passwords.
