• 2021/01/24: Runahead added - work around input lag in some games by running frames ahead of time and backtracking on input. DuckStation's implementation works with upscaling and the hardware renderers, but you still require a powerful computer for higher frame counts.
• 2021/01/24: Rewind added - you can now "smooth rewind" (but not for long), or "skip rewind" (for much long) while playing.
• 2021/01/10: Option to sync to host refresh rate added (enabled by default). This will give the smoothest animation possible with zero duped frames, at the cost of running the game <1% faster. Users with variable refresh rate (GSync/FreeSync) displays will want to disable the option.
• 2021/01/10: Audio resampling added when fast forwarding to fixed speeds. Instead of crackling audio, you'll now get pitch altered audio.
• 2021/01/03: Per game settings and game properties added to Android version.
• 2020/12/30: Box and Adaptive downsampling modes added. Adaptive downsampling will smooth 2D backgrounds but attempt to preserve 3D geometry via pixel similarity (only supported in D3D11/Vulkan). Box is a simple average filter which will downsample to native resolution.
• 2020/12/30: Hotkey binding added to Android version. You can now bind hotkeys such as fast forward, save state, etc to controller buttons. The ability to bind multi-button combinations will be added in the future.
• 2020/12/29: Controller mapping/binding added for Android version. By default mappings will be clear and you will have to set them, you can do this from Settings -> Controllers -> Controller Mapping. Profiles can be saved and loaded as well.
• 2020/12/29: Dark theme added for Android. By default it will follow your system theme (Android 10+), but can be overridden in settings.
• 2020/12/29: DirectInput/DInput controller interface added for Windows. You can use this if you are having difficulties with SDL. Vibration is not supported yet.
• 2020/12/25: Partial texture replacement support added. For now, this is only applicable to a small number of games which upload backgrounds to video RAM every frame. Dumping and replacement options are available in Advanced Settings.
• 2020/12/22: PGXP Depth Buffer enhancement added. This enhancement can eliminate "polygon fighting" in games, by giving the PS1 the depth buffer it never had. Compatibility is rather low at the moment, but for the games it does work in, it works very well. The depth buffer will be made available to postprocessing shaders in the future, enabling effects such as SSAO.
• 2020/12/21: DuckStation now has two releases - Development and Preview. New features will appear in Preview first, and make their way to the Development release a few days later. To switch to preview, update to the latest development build (older builds will update to development), change the channel from latest to preview in general settings, and click Check for Updates.

• 2020/12/13: Button layout for the touchscreen controller in the Android version can now be customized.
• 2020/12/10: Translation support added for Android version. Currently Brazillian Portuguese, Italian, and Dutch are available.
• 2020/11/27: Cover support added for game list in Android version. Procedure is the same as the desktop version, except you should place cover images in <storage>/duckstation/covers (see Adding Game Covers).

• 2020/11/21: OpenGL ES 2.0 host display support added. You cannot use the hardware renderer with GLES2, it still requires GLES3, but GLES2 GPUs can now use the software renderer.
• 2020/11/21: Threaded renderer for software renderer added. Can result in a significant speed boost depending on the game.
• 2020/11/21: AArch32/armv7 recompiler added. Android and Linux builds will follow after further testing, but for now you can build it yourself.

• 2020/08/20: Per-game setting overrides added. Mostly for compatibility, but some options are customizable.
• 2020/08/19: CPU PGXP mode added. It is very slow and incompatible with the recompiler, only use for games which need it.
