-/**
- * A simple GLSurfaceView sub-class that demonstrate how to perform
- * OpenGL ES 2.0 rendering into a GL Surface. Note the following important
- * details:
- *
- * - The class must use a custom context factory to enable 2.0 rendering.
- *   See ContextFactory class definition below.
- *
- * - The class must use a custom EGLConfigChooser to be able to select
- *   an EGLConfig that supports 2.0. This is done by providing a config
- *   specification to eglChooseConfig() that has the attribute
- *   EGL10.ELG_RENDERABLE_TYPE containing the EGL_OPENGL_ES2_BIT flag
- *   set. See ConfigChooser class definition below.
- *
- * - The class must select the surface's format, then choose an EGLConfig
- *   that matches it exactly (with regards to red/green/blue/alpha channels
- *   bit depths). Failure to do so would result in an EGL_BAD_MATCH error.

+Apple2ix (a2ix) 2.0.0-Android Release Notes
+
+TL;DR : new video mode settings!
+
+CHANGES:
+
+- Implemented a more conformant video scanner. This improves emulation fidelity for programs that implement custom video modes (e.g., custom split screen between text & graphics).
+
+- New NTSC video display modes including "Color monitor", "Monochrome TV", and "Color TV" modes. Thanks to the AppleWin project and Bill Simms for these modes. Also support "Green screen" monochrome video.
+
+- New preference to enable/disable half-scanline video effects.
+
+- EXPERIMENTAL: New preference to enable/disable fast disk image loading. This may cause audio glitches or other instability. Use at your own risk!
+
+GENERAL INFO:
+
+- More information about how to use Apple2ix for Android : https://deadc0de.org/apple2ix/android
