To disable this functionality and remove the ability for users to restore top folders from the recycle bin set:

New default value for:

Cleanup of Legacy System Archive Folder

The legacy system archive folder:

PowerFolders/BACKUP_REMOVE

is no longer used and can now be safely deleted after the configured system cleanup time.

Restoring top folder from system archive ("BACKUP_REMOVE")

Admins and users are now able to restore top-level folders direct from recycle bin.

More information about this feature: Server Audit Information

🌐WebDAV Token Validity

The default WebDAV token validity is now tecnically 21 years:

security.tokens.webdav.valid.time.seconds=662256000

Server admin can change this as per requirement.

Block folders of expired user

Server admin can now block the shared folders for all users when a account is expired.

Default:

server.account.block.folders.on.expiration=false

Set to:

server.account.block.folders.on.expiration=true

to block and unblock folders of an account when expired/valid again

🛡️Content Security Policy (CSP) Protection

To enhance security against Cross-Site Scripting (XSS) and other injection attacks, the application supports enabling Content Security Policy (CSP) headers. CSP allows the browser to restrict which content sources (scripts, styles, images, etc.) are allowed to load, preventing malicious scripts from executing.

Configuration

The CSP mechanism can be controlled via configuration flags in your server configuration file:

Options

• web.csp.enable

  • Default: true

  • Enables CSP headers in responses.

  • Set to false to completely disable CSP protection (not recommended).

• web.csp.report_only

  • Default: false

  • When false, CSP violations will block content that does not comply with the policy.

  • When true, CSP runs in Report-Only mode: violations are logged/reported, but the browser does not block the content.

  This is useful for debugging potential CSP false positives without breaking user functionality.

✨ New: Default user folders on first login

To simplify onboarding for new users, the system can now automatically create default folders at their first login.
Add the following to your Default.config (server maintenance):

🔄 Javascript in Email Templates

The email templates are also improved, please update the email templates or delete the old templates.

⬇️ Downgrade Information (optional)

• In case a downgrade to a previous version is necessary:

  • For a downgrade, you have to review our downgrade documentation.

  • Simply replace the PowerFolder-Server.jar file with that from the previous version you would like to run.

• Log messages due to the higher schema version of database can be ignored:

  • [DatabaseMigrator]: Database layout version is newer than expected.
