For installation and update purposes, we recommend to use the translate5 install & update routines. translate5 builds upon a number of other Open Source packages, tools and libraries and the translate5 updater will always care for the right version and all needed dependencies.
The current stable master branch of translate5 is published at bitbucket. It is split on several repositories, that are linked to each other as sub-repositories.
The latest official release of translate5 (without dependencies) can always be downloaded here.
