This release is a canary release intended to be used for testing.

#### Native desktop notifications

This release adds native desktop notifications on all supported desktop platforms. Backup results and other tray-icon notifications are now shown as real operating-system notifications instead of only appearing inside the UI.

On Windows, notifications are shown as Windows toast notifications with click-to-open support, thanks @JamBalaya56562. On macOS, notifications are shown via the native notification center. On Linux, notifications are sent over DBus and integrate with the desktop environment's notification daemon.

#### Native environment variable syntax on Linux and macOS

Paths and filters now support the native `$VAR` and `${VAR}` environment variable syntax on Linux and macOS, most notably `$HOME`, thanks @JamBalaya56562. Previously only the Windows-style `%VAR%` syntax was expanded, so the native forms were silently left unexpanded on non-Windows systems.

The expansion is additive: `%VAR%` keeps working everywhere, and an undefined variable is left as-is. If you previously worked around this with literal `$` characters in paths or filters, those entries will now be expanded.

#### Restore improvements and fixes

Several restore issues have been fixed in this release, thanks @JamBalaya56562. Restore now honors stop requests promptly: an abort interrupts in-progress file reads and writes, where it previously could keep running for minutes after the request. An aborted restore no longer reports errors, blames the backup, or leaks temporary files, and files that a shutdown interrupted are no longer listed as broken. A requested shutdown is in general no longer reported as a failure. Two bugs that could corrupt restored data were fixed: a wrong seek offset when copying verified local blocks, and an incorrect buffer copy when merging a hash fragment. Restore now also preserves the selected folder and applies configured default options (such as `--restore-permissions`) when the restore request does not explicitly specify them. On the legacy restore engine, restoring a directory symlink no longer creates a real folder in its place.

#### Stricter validation of settings

This release adds validation in places that previously failed silently, which may surface new warnings or errors after upgrading:

- Misconfigured filters are now detected and reported with a warning, instead of silently matching nothing.
- An unusable update check interval is now rejected instead of being ignored.
- An invalid webservice timezone now fails instead of being silently reset.
