Though AnyToISO is not open-source, we use this GitHub repository to track bugs, feature requests and technical support problems (see issues).
The repository also contains AnyToISO translations as .xml files. Fork the repository, update existing translation (or create a new one) and simply create a pull request. Always leave %1 (%s), %2, etc in the string, it's a replacement pattern required by the program. For example the string "Package %1 opened" will be expanded to "Package firefox4pre opened" when opening Firefox browser package.
Release archive contains the list of binaries for every version of the app with release notes.
