Uhm, I have noticed this message now (I need to enable notification for this topic).

In 0.8 it a good idea to avoid secret chats because they are unstable.

The master branch of Sailorgram on GitHub needs to be adjusted because I have tried to integrate the new version of the library that I was using (the Cutegram ones) but it's incomplete, buggy and unsuitable for a mobile device, and they are becoming obsolete again (they use an older layer now).

Currently I'm developing a dedicated library which uses the latest Telegram APIs (Layer 57) and I will begin the integration on Sailorgram next month, after that I will begin a new (public) 0.9 beta testing session during the end of November (if the integration goes smoothly).

The new secret chats implementation will be added during beta testing sessions and they will be available out of the box in the stable 0.9.
