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.
Release Notes: Bugs with HTTP chunked transfers on Python 3 and with the new <file> support producing empty files were fixed. The mirror service is no longer called if a download is slow because it is queued or waiting for user interaction. The desktop launcher is now a single item, making it easier to use from Unity and GNOME 3. Performance has been improved when running apps, especially on Arch Linux.
Release Notes: A new search feature makes it easier to search for available software. 0install now works with win-bash, simplifying creation of cross-platform source releases. Download recipes can fetch individual files, not just archives (useful for, for example, jar files). The Tulip Python mainloop can be used if GObject isn't available. XZ compression is now supported in .deb archives.
Release Notes: This release enhances the XML package metadata syntax, allowing more precise specification of dependencies. Support for using distribution-provided packages as dependencies has been extended and now covers Arch Linux, Cygwin, Darwin, Debian, Fink, FreeBSD Ports, Gentoo, MacPorts, Mint, openSUSE, Red Hat, Slackware, and Windows. The 0install software now supports apps, an easier way to manage 0install applications, improved diagnostics when no compatible versions can be selected, improved usability, and better support for use on headless servers.
Release Notes: Running an app when some previously selected packages are no longer present now forces an update in the foreground. Arch-style Java version numbers are now supported. The Makefile now copes with Arch's Python naming. Various minor bugs were fixed. This is a 2.0 release candidate.
Release Notes: 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.
