Release Notes: Installing to your home directory is now simpler. A new --show option provides an easy way to see where downloaded packages are stored on disk. The new "alias:prog" syntax can be used as a short way to specify a URI. The key confirmation process is simpler in the case where the key is known to the key-info server (and harder when it isn't).
Release Notes: Support for PackageKit was added, so that if a Zero Install program depends on a distribution package, the user can install that too at the same time. Bug reports now automatically include versions of all dependencies in XML, allowing the upstream author to recreate the reporter's environment exactly. A number of localization issues were fixed, and Windows support continues to improve.
Release Notes: If there are multiple packages available for different locales, Zero Install can now automatically select the right one. Support for dependencies on native Slackware packages has been added. If a program depends on a Debian package which isn't installed, the user is now prompted to install it.
Release Notes: The distribution integration now also supports FreeBSD Ports. Apple dmg-format archives can be used on Mac OS X. More accurate architecture information is now read from Debian, RPM, and Gentoo native packages. Some encoding issues were fixed with error messages in non-English locales.
Release Notes: The algorithm used to select the set of package versions to use was replaced by a proper SAT solver. The new algorithm will always find a solution if one exists, even in complex situations involving multi-arch systems or dependencies on native distribution packages.
Release Notes: Support for Gentoo native packages was added to the existing support for RPM and Debian packages. Native package names can be given for specific distributions. If multiple digest algorithms are available, they are ranked, and the best one used. Path handling was improved to provide better support for Windows.
Release Notes: Download progress can now be displayed when running in console-only mode. CPU type names are now canonicalised, not operating system specific. Support for GnuPG 2 was added. Some minor bugs were fixed.
Release Notes: Support for xz compressed tars and more compression types inside Debian packages was added. Feeds can now be fetched over HTTPS. Dependencies can be flagged as only needed when running unit tests. A Spanish translation was added. Some minor bugs were fixed.
Release Notes: A bug that prevented 0launch from started with the latest GTK in Debian/unstable was fixed. Programs that need to run in a terminal emulator are now started correctly.
Release Notes: When a new GPG key is seen, Zero Install is able to look up information about it from a server. The default service informs you if the feed is signed by a member of the Debian project, in addition to showing information from the old database. Distribution integration now also works with multi-arch RPMs. libglade is no longer a dependency. Internationalization support has been improved.
