Dangerzone 0.9.0 released

Wed Apr 09 2025

We're pleased to announce that Dangerzone 0.9.0 has been released. This release mostly includes stability improvements and security fixes, with a few new features.

If you are on a Mac or Windows, please also update Docker Desktop to version 4.40.0 or later, as previous versions contain known bugs that prevent Dangerzone from converting documents. On Windows, you will need to uninstall any Dangerzone version prior to 0.9.0 before installing this one.

For this release, the highlights are:

The container image is now reproducible across different container runtimes and versions (#1074). As part of this effort, the image used to run the conversion is now based on Debian (it was previously based on Alpine Linux) (#1046).
Outdated Docker Desktop versions are now highlighted in the user interface and the user is asked to upgrade (#693).
The CLI can now run with a --debug flag to help retrieve more logs (#941).
Experimental support is now available for Podman Desktop on Windows and macOS (docs)
