 `TDLib` has many advantages. Notably `TDLib` is:
 
-* **Cross-platform**: `TDLib` can be used on Android, iOS, Windows, macOS, Linux, FreeBSD, OpenBSD, NetBSD, Windows Phone, WebAssembly, watchOS, tvOS, Tizen, Cygwin. It should also work on other *nix systems with or without minimal effort.
+* **Cross-platform**: `TDLib` can be used on Android, iOS, Windows, macOS, Linux, FreeBSD, OpenBSD, NetBSD, illumos, Windows Phone, WebAssembly, watchOS, tvOS, Tizen, Cygwin. It should also work on other *nix systems with or without minimal effort.
 * **Multilanguage**: `TDLib` can be easily used with any programming language that is able to execute C functions. Additionally it already has native Java (using `JNI`) bindings and .NET (using `C++/CLI` and `C++/CX`) bindings.
 * **Easy to use**: `TDLib` takes care of all network implementation details, encryption and local data storage.
 * **High-performance**: in the [Telegram Bot API](https://core.telegram.org/bots/api), each `TDLib` instance handles more than 24000 active bots simultaneously.
