 # Future
 
+# 1.9.10
+- 3DS: Add bottom screen idle state
+- 3DS: Add unique IDs for Gearboy/Gearcoleco/Gearsystem, correct CAP32 code
+- 3DS/SAVESTATES: Fix RAM states to file when core deinits
+- AUDIO/MIXER: Pad sample buffers to prevent potential heap-buffer-overflows when resampling (fixes crash when using 30 kHz menu audio files)
+- CHEEVOS: Don't write achievement credentials to overrides
+- CHEEVOS: Disable slowmotion when enabling hardcore mode
+- D3D9: Fixed MVP matrix issue for RGUI texture (main game frame still won't show up though)
+- D3D11/D3D12/HDR: Fixed contrast to be more correct - now scales from 0-10 linearly and behaves more the way you'd expect it to - changed name to ditch legacy settings users may have
+- D3D11/HDR: Fixed D3D11's blend, rasterizer and topology states not being set to the sames when using HDR and leaving the menu - caused issues with PCSX2's Shadow of the Colossus
+- D3D11/D3D12/HDR: Added ability to skip inverse tonemapper to the shader via the constant buffer using 'inverse_tonemap' - set to 0.0f to skip
+- D3D11/D3D12/HDR: Fixed potential bug when swapping between hdr and sdr and the bit depth not being set correctly
+- D3D11/D3D12/HDR: Added numerous helper functions to help create the correct values to colour the UI - normally the white UI elements should be rendered at paper white not max brightness for various reasons
+- BUGFIX/ANDROID: Fix crash that could happen on Android with Sameboy core - would crash on rumble function
+- GFX/WIDGETS: New regular widget message appearance
+- INPUT/MOUSE: Add distinct mouse zero index label for drivers that do not support multimouse
+- INPUT/RUMBLE: Add generic rumble gain to input settings
+- INPUT/UDEV/X11: Add workaround to fix keyboard input when using X11 + Udev
+- LIBNX/SWITCH: Add Video Filters support
+- LOCALIZATION: Fetch translations from Crowdin
+- OPENDINGUX/BETA: Disable OpenAL
+- PLAYLISTS: Add 'Refresh Playlist' option
+- UWP/VFS/XBOX: Improvements and bugfixes to UWP VFS driver
+- VIDEO/REFRESH RATE: Automatic PAL/NTSC refresh rate switch where available - as long as the platform display server allows changing refresh rates and the display has the desired refresh rate
+- VIDEO FILTERS: Add 'Picoscale_256x-320x240' video filter
+- WIIU/HID: Fix analog inputs on HID devices
+
+# 1.9.9
+- 3DS: Add bottom touchscreen menu
+- 3DS/SAVESTATES: Save and load save states to and from RAM
+- AUDIO/MIXER: Ensure than menu sounds are re-enabled when calling CMD_EVENT_AUDIO_REINIT
+- AUDIO/RESAMPLER/MIXER: Fix menu sounds (audio mixing) when using the 'sinc' resampler with quality lower than 'normal'
+- AUDIO/CONVERSION/ARM NEON: Add intrinsic NEON versions for float_to_s16/s16_to_float - should lead to optimized codepaths for AArch64/ARMv7 architectures without being dependent on ASM codepaths.
+- AUDIO/RESAMPLER/ARM NEON: Add intrinsic NEON version for lanczos sinc function - should lead to optimized codepaths for AArch64/ARMv7 architectures without being dependent on ASM codepaths.
+- CHEEVOS: Upgrade to rcheevos 10.2
+- CHEATS: Add enhanced search functionality to the 'Cheats' menu
+- CHEATS/RUNAHEAD: Fix cheats when using second instance runahead
+- CONFIG: Add option to (force-)write current core options to disk (Quick Menu)
+- CORE INFO CACHE: Remove core path from core info cache. Should make core info caches portable now (for example: you can move RetroArch to a separate dir and they would still work).
+- D3D11: Use Shader Model 5.0 for frontend shaders if D3D11 Feature level is at least 11.0 or higher. Should fix some new shaders that require SM 5.0 (like AMD FSR)
+- D3D11: Add HDR support (disabled for UWP for now)
+- D3D12: Add HDR support (disabled for UWP for now)
+- EMSCRIPTEN: Fixed web player bug with filesystem and runtime
+- INPUT/OVERLAY: Fix overlay input when analog to digital mapping is enabled
+- INPUT/UDEV: Look for "ID_INPUT_KEY", not "ID_INPUT_KEYBOARD"
+- INPUT/WINRAW: Fix crash when overlay is enabled
+- MAC/METAL: Add Discord RPC support
+- MENU: Allow 'Custom Aspect Ratio (X Position)/(Y Position)/(Width)/(Height)' to be entered manually via keyboard
+- MENU: Allow 'Vertical Refresh Rate' to be entered manually via keyboard
+- MENU/SHADERS: Highlight currently selected value in Shader Parameter drop-down lists
+- STABILITY: Safer way of avoiding the race condition in
+audio_driver_sample/audio_driver_sample_batch - we can check
+audio-suspended to see if we're doing a fs/windowed toggle - enhances stability when fullscreen toggling/tearing down context
+- STABILITY: When audio driver write callback function fails, don't
+turn audio off completely - look if audio_driver_output_samples_conv_buf
+is non-NULL first before we attempt to write audio - enhances stability when fullscreen toggling/tearing down context
+- STABILITY: Input robustness for cores that use internal threading
+(full teardown/setup), no audio should be processed at this point in
+time
+- VIDEO: Screen resolution list sanitizing
+- VULKAN: Fix some Vulkan validation layer errors
+- UWP: Updated icons courtesy of Danp142
+- UWP/XBOX: Disable CPU model check on Xbox as it doesn't work and can even crash
+- UWP/VFS/XBOX: Code cleanup and simplification of UWP VFS driver

 # 1.9.8
 - AUDIO/WINDOWS/WASAPI: Stop deactivating audio on fast forward
 - CHEEVOS: Hide challenge indicators when resetting

 *** BEST PRACTICES ***
 
-* If we have pointers and size variable pairs, it's best to interleave them to increase the probability they go in the same cacheline. It also makes the code more readable, that these two variables are connected.

 Stack size
 ----------
 
-You have to assume that stack size is going to be limited in RetroArch. Some game consoles (and other embedded systems) might have a default stack size as low as 128Kb or less. Be conservative with stack size but don't try to put very small structs on heap either [to avoid memory fragmentation among other things].
+You have to assume that stack size is going to be limited in 
+RetroArch. Some game consoles (and other embedded systems) 
+might have a default stack size as low as 128Kb or less. 
+Be conservative with stack size but don't try to put very 
+small structs on heap either [to avoid memory fragmentation 
+among other things]. A balancing act here is necessary.
 
 Be mindful that heap allocations are slow compared to stack.
+
+Functions
+---------
+- Avoid doing small getter/setter functions. We want a function 
+to justify its function call overhead by doing a significant 
+body of work. Small one-line getter/setter functions for what 
+is predominantly C-style structs is not useful, plus it leads 
+to people thinking this function is more complex than it 
+actually is, thus obfuscating the sourcecode instead of it 
+being easier to read.
+
+If you can find examples in the codebase that violate this 
+guideline, do not hesitate to point them out to us.
+
+Variable declaration
+--------------------
+For C source files, we have to insist you stick to the following:
+
+- Declare variables either at the start of a function or the start 
+   of a code block, depending on the scope they need.
+- Do not do initial for loop declarations. Refer to the bulletpoint above:
+   either declare them at the start of the function, or at the start
+   of the code block.
+
+Not doing this would break compilation on platforms where we are compiling
+these C source files in C89 compatibility mode. If such issues occur in pull
+requests, we have to request that it be fixed.
+
+VLA (Variable Length Array)
+---------------------------
+Do not use VLAs (Variable Length Array) in C source files. These are not
+C89-compliant.
