 #### 2.3 Test Application
 You can see how MobileFFmpeg is used inside an application by running test applications provided.
-There is an Android test application under the `android/test-app` folder and an IOS test application under the 
-`ios/test-app` folder. Both applications are identical and supports command execution and video encoding.
+There is an Android test application under the `android/test-app` folder and an IOS test application, which requires 
+`Xcode 9.x` or later, under the `ios/test-app` folder. Both applications are identical and supports command 
+execution, video encoding, accessing https, encoding audio, burning subtitles and video stabilization.

 ### 3. Versions
 
-- `MobileFFmpeg v1.x` is the current stable, includes `FFmpeg v3.4.2`
+`MobileFFmpeg` version number is aligned with `FFmpeg` since `v4.2`. Before that `MobileFFmpeg` version of a release and `FFmpeg` version included in that release was different.
 
-- `MobileFFmpeg v2.x` is the next stable, includes `FFmpeg v4.0.1`

-### 4. Building
-#### 4.1 Prerequisites
+### 4. LTS Releases
+
+Starting from `v4.2`, `MobileFFmpeg` binaries are published in two different variants: `Main Release` and `LTS Release`. 
+
+- Main releases are published every 3 months. They include complete functionality of the library and support the latest SDK/API features.
+
+- LTS releases are published every 6 months. These releases are customized to support a wide range of devices. They are built using older API/SDK versions, so some features are not available for them.
+
+This table shows the differences between two variants.
+

+#### 5.2 Build Scripts
 Use `android.sh` and `ios.sh` to build MobileFFmpeg for each platform.
 After a successful build, compiled FFmpeg and MobileFFmpeg libraries can be found under `prebuilt` directory.
 
 Both `android.sh` and `ios.sh` can be customized to override default settings,
 [android.sh](https://github.com/tanersener/mobile-ffmpeg/wiki/android.sh) and
 [ios.sh](https://github.com/tanersener/mobile-ffmpeg/wiki/ios.sh) wiki pages include all available build options.

 Their source code is not included in the repository and downloaded when enabled.
 
-#### 4.4 External Libraries
+#### 5.4 External Libraries
 `build` directory includes build scripts for external libraries. There are two scripts for each library, one for Android
 and one for IOS. They include all options/flags used to cross-compile the libraries. `ASM` is enabled by most of them, 
 exceptions are listed under the [ASM Support](https://github.com/tanersener/mobile-ffmpeg/wiki/ASM-Support) page.
