From now on, the minimum system version required for beta APKs published in this channel is Android 7 (Nougat).

However, Telegram X still supports older Android versions down to Jelly Bean 4.1. The support for them just moved to different APKs.

Be aware of scams, the only official ways to get APKs that support older Android versions:
- Google Play beta (after review)
- Releases on Github
- Wait for stable version (APKs with support for older Androids will be published here, but only for stable versions).
