Zero Install Injector

This release adds support for Python 3, PyGObject, and GTK 3 (while continuing to support Python 2, PyGTK, and GTK 2). A new directory naming scheme supports cmake and other programs which can't cope with "=" characters in pathnames. The new <restricts> element allows adding version constraints without creating a dependency. The new <rename> recipe step allows renaming files and directories when unpacking. Various minor bugs have been fixed.

The new "apps" support records current and past selected versions of programs and their dependencies, allowing easy rollback to previous states and improving startup time. Windows support has been improved to the point that tools such as 0compile now work on Windows also. Managing locally-compiled packages is now simpler.

Arch Linux native packages can now be used as dependencies. "0install update" informs the user if a newer version exists but was not selected for some reason. A workaround was added for Python's lack of SSL hostname checking. Various minor bugs were fixed.

A progress indicator was added for 0store optimize. Native Java JREs and JDKs are now detected on Windows. Various minor bugs were fixed.

Support for MacPorts was added, so that packages installed this way can be used as dependencies. A number of minor bugs were fixed, including support for detecting multiple versions of a native package (e.g. for multi-arch systems) and batching PackageKit requests to avoid the transaction size limit.
