Release Notes: 0install 2.6 completes the transition from Python to OCaml. There is no remaining Python code in 0install and, therefore, no need to have Python installed in order run it. 2.6 also adds support for the Raspberry Pi and a JSON API for interfacing with other systems.
Release Notes: More code has been migrated from Python to OCaml. The logic for handling mirrors has been improved. The cache explorer now works when the cache is larger than 2GB.
