Release Notes: This release fixed detection of 64-bit Windows systems, a bug in the recent Ruby gems support, and an error when multiple PackageKit versions are available.
Release Notes: Packages can now express a dependency on Python even on platforms without native-packager integration. The cache explorer user interface has been much improved. The Compile button now performs a recursive auto-compile (compiling build dependencies too).
Release Notes: New keys can be approved automatically if known to the key-info server. Support for the Ruby gem archive format was added. The rules for finding the best language match have been improved. A bug in the new <runner> feature was fixed.
Release Notes: An improved command-line interface is provided through the new "0install" command. The GUI display is clearer when no suitable version of a component can be found for some reason. The 0alias command works better when no writable directory is found. The <runner> element can now be used recursively (e.g. an E program needs to be run by the E interpreter, which in turn needs to be run by Java). The Windows version is now considerably more usable.
Release Notes: A new <command> element provides a more flexible way to specify how a program is run. It allows extra arguments to be passed (including the locations of dependencies) and allows specifying the interpreter used to run this program.
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.
