Есть уже собранные приложения? Для IOS и android.
Обход это чудесно, только без готового решения, смысла от него не много..
Спасибо за труды. Если уже есть, добавьте ссылки, еще раз спасибо.

All checks are passed. Still in test?

12.6.2 ios stable released

confirmed community fix TLS ClientHello MTProto-EE

[b0r1ngx]

But how it possible that iOS stable released with that community fix, when this fix isn't merged.

Doesn't Telegram App that we download from App Store have to be built from this repository?

Where can we check the concrete TLS fix commit that was merged in Telegram App that is in App Store, to prove that is really Open Source Project?

This GitHub repository is a public mirror of an internal Telegram's GitLab. Telegram usually updates public source code as soon as the new major/minor version is available in App Store. This is a manual process, so don't expect it to be instant.

Once available, you can find a particular 12.6.2 commit in the list if tags and make a reproducible build.
