TYPO3 14.2 will add native support for 🇱🇦 Lao language.

https://github.com/TYPO3/typo3/commit/734f5ef5208e24c56925998ce9a19652525102d5

Since a couple of days, TYPO3 is fully translated to Lao. 💪
Also some popular extensions have been translated, more to follow.

But you can also use the translation in older TYPO3 versions by adding some manual configuration to your TYPO3 installation:
