The following table details the current state of the translations of the LyX GUI for the LyX development branch (version 2.5.0), which will become the next major release.
Explanation:
- Language: The supported languages. The list is ordered by completeness.
- Translated: The number of translated messages.
- Fuzzy: The number of fuzzy messages; these are not considered for LyX output but solely serve as a hint for the translators.
- Untranslated: The number of untranslated messages; the default language (i.e., English) will be used instead.
- The color indicates completion status:
- dark green: translation completed.
- light green: translation more than 66% completed.
- orange: translation more than 50% completed.
- red: translation less than 50% completed. These translations are likely to be dropped from future releases of LyX, if no further work is being done on them.
