Zero Install Injector

Requirements can now be restricted to a particular distribution, allowing e.g. MacPorts Python libraries to specify that they work only with MacPorts Python. Environment variables can be expanded into multiple arguments, which is useful for passing options. .NET Framework installations are now detected on Windows. The diagnostics displayed when no selection is possible have been further improved to show the restrictions that prevented the selection of each candidate.

Zsh and bash completion support has been added for the "0install" command.

Support for the latest PackageKit API (0.8.1) has been implemented.

The --dry-run feature now does a full dry-run,
instead of stopping at the first download.

"0install show" displays the current selections for an app.

Various minor bugs have been fixed.

Much-improved diagnostics are now shown when no compatible selections are possible. There's a new syntax for specifying versions on the commandline, including version constraints for dependencies. The naming scheme for site-local packages (compiled binaries) has been changed to avoid characters which confuse some programs. User-selected cache directories now add to (rather than replace) system paths. Selections update automatically on configuration changes (without waiting for the next update check).

Support was added for OS-specific dependencies (e.g. for dependencies only needed on Windows) and for constraints in native package implementations (e.g. Debian's python3-gi package cannot be used with Python 2). "0install man" allows the man command to work with 0install applications. "0install digest" now has an option to display the manifest. A bug in the PackageKit support which meant it sometimes failed to detect candidate packages was fixed.

Support for finding native Java packages has been improved to support multiple distribution-provided versions. Replaced interfaces now conflict with their replacements. A number of bugs were fixed, particularly relating to the recent Python 3 support.
