This release introduces a major new Staging Sites feature for Pro/Elite users, allowing one-click creation of isolated WordPress staging environments directly from the Duplicator admin. The backup interface gains deep Activity Log integration for audit trails and automatic cleanup of failed backups. Backups stored in Duplicator Cloud can now serve as recovery points without requiring local storage. Several reliability fixes address FTP upload issues on Windows servers, installer search-replace overflow, NFS hosting failures, and password-protected archive imports.
Plugin:
[NEW] Added Staging Sites feature (Pro/Elite only): create and manage isolated WordPress staging environments in subfolders directly from the Duplicator admin; includes automatic database isolation with unique table prefixes, automatic exclusion of staging tables from production backups, license management (auto-activation after migration, deactivation on deletion), safety restrictions (email blocking, search engine indexing disabled, Duplicator menus hidden, visual admin bar indicator on both frontend and backend), and support for multiple staging sites per installation
[NEW] Integrated Activity Log support: failed backups are filtered from the main backup list and tracked in Activity Log with automatic 6-hour cleanup; backup deletions, storage removals, and orphan file cleanup are now fully audited with detailed metadata; admin notices guide users to Activity Log when failures occur
[NEW] Backups stored exclusively in Duplicator Cloud can now serve as recovery points without requiring local storage; the restore configuration file is now uploaded alongside every backup with structured eligibility metadata
[UPD] Improved backup upload performance: storage validity is now checked once at upload start instead of on every batch iteration
[UPD] Backup storage directory renamed from backups-dup-pro to duplicator-backups; existing installations are automatically migrated on upgrade
[UPD] Plugin version is now displayed in the backup details row
[UPD] Cloud downloader files are now detected during pre-backup validation and automatically removed during post-installation cleanup
[FIX] Fixed FTP (cURL) adapter returning empty file listings on Windows FTP servers (IIS) due to trailing \r characters in filenames
[FIX] Fixed FTP (cURL) adapter temp file leaks that could cause disk exhaustion on high-volume backup servers
[FIX] Fixed intermittent file-read failures on NFS/clustered hosting environments (e.g. SiteGround) by adding retry logic with cache clearing
[FIX] Fixed fatal PHP error during database scan when MySQL returns NULL for table statistics on InnoDB tables
[FIX] Fixed JavaScript security vulnerabilities (Handlebars RCE/prototype-pollution, formstone XSS) by updating npm dependencies
