#### 2026-08-26 - 2.3.1.1_beta_2026-08-26

This release is a Beta release intended to be used for testing to identify any issues before releasing the next stable version.

#### Partition level full disk backup and restore

The full disk backup feature now supports selecting individual partitions as backup sources, in addition to entire disks. This makes it more intuitive to back up a specific partition without filtering.

Restore now also supports partition-to-partition restores, so it is possible to restore a single partition from a full disk backup, or restore a partition backup to a different partition.

#### Desktop notifications on all platforms

Desktop notifications are now supported on all platforms. Windows toast notifications have been implemented (with click-to-open support), and native notification support has been added for macOS and Linux (via DBus), thanks @JamBalaya56562.

#### Restore cancellation and reliability improvements

Several issues with the restore process have been fixed. Restores now properly respond to stop/abort requests, file reads and writes can be interrupted, and a critical bug with wrong seek offsets for partial blocks has been fixed, which could cause restores to fail for most files, thanks @JamBalaya56562.

#### Misconfigured filter detection

A new warning system detects when filters are configured to unconditionally exclude everything. A post-backup check also warns if no files were examined during backup, which helps catch misconfigurations that would otherwise silently produce empty backups.

#### More robust server connection

The remote server connection has been hardened against network events that could cause it to drop. A watchdog monitors the connection and restarts it if it has been unresponsive for an extended period.

#### Improved MS365 license counting

The MS365 license counting logic has been simplified. A Duplicati license is now required if an MS365 license is assigned, without needing per-user lookups. The same logic applies to both users and sites, and personal sites of users without a license are not counted.

#### Faster delete operations

The database query for deleting old backup versions has been optimized, significantly speeding up the delete operation for large backups.

#### Fixed index file recreation

An issue where recreated index files could be incomplete has been fixed. The index file recreation now happens after block volumes are fully processed, ensuring all blocklists are included. This fixes the intermittent "Found N faulty index files" verification error.

#### Security fix for credential leaks

Fixed an issue where credentials embedded in URLs could leak into log messages, but only on malformed URLs, thanks @JamBalaya56562.

#### Auto-configure database metadata

When using a source provider that requires database metadata (such as full disk backup), the `--store-metadata-content-in-database` option is now automatically applied when needed. This can still be overridden manually.
