This release is a canary release intended to be used for testing in preparation of a later stable release.

Unlike regular canary builds, this one has a major change in the build system, so it now runs on .NET8.

For that reason, the updater in previous canary builds does not detect this update yet, but this can be activated at a later time.

Important changes from last Beta

• Updated to .NET8 with OS specific builds
• Using Kestrel as the API/UI server
• Mandatory password and new authentication scheme
• Settings database version updated to v8
• Encrypting data in Duplicati-server.sqlite with machine serial number

Please see list of known issues related to .NET8/Kestrel upgrade:
https://github.com/orgs/duplicati/projects/2

New tool to manage a running server

Due to incompatibility with duplicati_client a new tool is included, named Duplicati.CommandLine.ServerUtil.exe/duplicati-server-util.

The new tool can pause/resume a backup, run a backup, change the password and more:
https://github.com/duplicati/duplicati/pull/5483

Encrypting database fields

To reduce the risk of leaking encryption passphrases and credentials,
many fields in the Duplicati-server.sqlite file will be encrypted after running this version.
The key used to encrypt is derived from the machine serial number, so the database cannot be decrypted on another machine.

If your strategy relies on being able to read this database, you must take action.
These two setups are vulnerable:

• If you do not store a copy of the passphrase elsewhere
• If you make a copy of the settings database

We strongly recommend that you store a copy of the passphrase(s) securely, regardless of your setup.

If you want to choose the settings encryption key, you can set the environment variable SETTINGS_ENCRYPTION_KEY to a custom value.
If you want to never use the serial number as the passphrase, set the environment
variable DUPLICATI__REQUIRE_DB_ENCRYPTION_KEY=true, which will prevent Duplicati from starting without a user provided key.

If you need to change the key, you can temporarily decrypt the database by starting the server with --disable-db-encryption.
After starting, stop the instance again, set SETTINGS_ENCRYPTION_KEY and start again without the argument, to have it re-encrypted.

To downgrade from this version, run once with --disable-db-encryption, and change the version number to 7, then install the previous version.

As always, feedback is appreciated!

This build is changes the underlying webserver to Kestrel, which is common for .NET based projects.
A big thanks to @tsuckow and @npodbielski for their contributions towards this goal.

This build changes authentication for the WebUI
With this build it is no longer possible to use the web-UI without a password.
If no password is set, a random password is generated.
For users activating the UI via the TrayIcon, this will automatically log in, as the TrayIcon hosts the server.
For users that rely on the WebUI without the TrayIcon, as special link is emitted during startup that allows login.
For both cases, the password can be (re-)set with --webservice-password=... as a startup commandline argument.

Detailed list of changes:

• Updated libraries: Mega, SharpAESCrypt, Storj, FluentFTP
• Updated Webserver to Kestrel, thanks @tsuckow and @npodbielski
• Implemented websocket based messages in WebUI, thanks @npodbielski
• HTTP reports now give a warning if the server rejects the message
• Extensive changes to strings to improve localization, structure and layout in WebUI, thanks @luixxiul
• Uplink libraries fixed on all platforms, thanks @TopperDEL
• Fixed an issue where strings with line-breaks would not show in translated form
• Removed remnants of Tardigrade backend in favor of Storj API
• Added Sakura Cloud to list of S3 providers
• Changed aFTP default SSL to None, meaning "System Default"
• Added check to find Duplicati server database in old location on MacOS
• Fixed issues with .deb packages overwriting options file on update
• Fixed issue with backups using VSS and a drive letter as the source
• Fixed issue with Arm 32bit not reading files larger than 4GiB

These are some of the major changes that can cause surprises, so please review and see if any are relevant for your usage:

• Changed runtime to .NET8, shipping with dependencies, no more Mono or .NET install required
• Changed from portable executable to operating system and CPU architecture dependent packages
• Server database with SQLite is no longer "encrypted" with RC4, running a new canary or later will decrypt the database
• The executable Duplicati.Library.AutoUpdater.exe is renamed to Duplicati.CommandLine.AutoUpdater.exe and has limited functionality
• The Windows MSI installer has been reduced, it offers essentially no options for now and no UI
• The updater has been rewritten to rely on installing the packages, instead of having the "in-place" updates
  • There are now longer a spawned secondary process
  • The updates folder can be deleted
  • Installing an update now requires manually downloading and running the installer (you still get a notice)
• To fit better with non-Windows systems the executables on non-Windows are all lower-case and prefixed with duplicati:
  • Duplicati.GUI.TrayIcon.exe -> duplicati
  • Duplicati.CommandLine.exe -> duplicati-cli
  • Duplicati.RecoveryTool.exe -> duplicati-recovery-tool
  • ... and similar for others

The new releases will be built with the framework included for minimal dependencies.

Thanks to all the amazing contributors and community for supporting the project!

For this release the following major changes are included:

• Updates to various third-party libraries: mail, Ssh.Net, RestSharp, FluentFTP, Sharp.Xmpp, Uplink
• Improved error handling with interrupted backups and damaged local database
• Removed defunct links and backends

Changes in this version:
This build is intended to be the last build that uses .Net4 (aka .Net Desktop).
Future builds are expected to use .Net8 and will require a manual update,
because the .Net builds are no longer operating system independent.

The upside is that there are fewer dependencies (no more Mono),
and execution times are greatly improved.

Changes in this version:
After almost 2 years, a new Beta has taken its time, but it’s finally
there. It’s a roll-up of all the fixes since the last beta build and is
expected to cause very few issues when upgrading. This release is almost
identical to Canary 106.

It involves a better UI for dark mode, better support for Dropbox,
Jottacloud, S3, Tencent backends, add IDrive backend, TLS modernization,
bug fixes, upgrades to libraries.

Points of attention:

• database upgrade from 11 to 12: Downgrade from this version requires
  manually adjusting the version
  number in the database. The additions can be re-applied if the database is
  upgraded again later.
