0.21.7.1151 cloud localizations are fully supported.You can now create your own localizations for Telegram X on Translations Platform and use links like these to share them with others:
https://translations.telegram.org/en/android_x
https://t.me/setlanguage/zh-hans-beta
https://t.me/setlanguage/zh-hant-beta
In-app tools for creating translations files will remain. Old localization files still can be installed and imported into your cloud localization.
Since all changes appear on the translation platform and this channel is no longer useful, it will no longer be used.
Thank you for translating Telegram X to your language!
