CORE: Set compute fps stats logging to debug level
EMSCRIPTEN: Added M2000 to core selection dropdown
FFMPEG: Add compatibility with FFMPEG 7.0
GLSLANG: Remove unneeded ENABLE_HLSL code from glslang
GENERAL: Memory leak: Dynamic allocation from msg_hash_get_help_us_enum was not freed.
INPUT/KEYBOARD: Add support for multimedia keys – Extended RETROK_ values with 18 new items, commonly found on
“multimedia” keyboards. Mapping added for SDL, X11, Wayland, dinput, winraw keymaps.

macOS/iOS/tvOS: enable text-to-speech using AVSpeechSynthesizer.
tvOS: Fix scaling for 720p
MENU: New function in Quick Menu: Add to Playlist
MENU/XMB: New theme: FlatUX, designed to merge FlatUI and Retroactive themes into a single, unified design
NETWORKING/RETROPAD CORE: Fix socket close method
PIXMAN: Update pixman-private.h – patch to fix build issue with musl
PLAYLIST: Cleanup ‘Add to Playlist’ (#16495)
SCANNING: Fix for scanning PSP ISOs (and probably few others)
SAVES: Fix core config saving
SAVES: Fix save new config name when core loaded
SAVESTATES: Increase save state chunk size for all platforms – Even a class 6 or class 10 SD card can handle reads and writes on the order of MB/s, which means a 4KB chunk size is just wasting time in syscalls. This could maybe be fixed with a buffering reader but I don’t feel comfortable tweaking libretro-common’s VFS to handle that. Instead, I thought it would be good to both remove an ifdef and increase the chunk size to 128KB. For cores with small states this will should make state saving virtually instantaneous, and for cores with large states it should be a 32x speedup.
VIDEO: Fix crash when using threaded video – for Mesa 23.2 and later
VIDEO/GL: Fix reinitialization of the threaded gl drivers
VIDEO/VULKAN: Add support for A2R10G10B10 HDR format

WAYLAND: Use frontend signal handler to quit (fix quit by window close)
WAYLAND: Commit viewport resizes (window resize is more responsive)
UWP: Align MESA to alpha-2-resfix – Remove wrong resolution special handling for OPENGL
UWP: 4K fix: align MESA reading of ClientRect to retroarch procedure, this fixes max resolution being set to 1080p. As reading must be done inside an UI thread and is in fact an async operation which might delay frame generation, the reading itself is doen once and cached, give that changing resolution while the app is running is an unlikely corner-case use
WINDOWS: Windows mouse ungrab must release the mouse instead of confine it to the current desktop (#16488)
WINDOWS: Fix numlock/pause key release events
AI: Fix narrator language when AI translation and menu languages are different
DISK CONTROL: Add option to disable initial disk change

OSX/MACOS: Add portable.txt as flag for portable install
REMOTE RETROPAD: add display for analog axes, indication of inputs already pressed
SAVES: Allow combining saves in content dir with save sorting
SHADER: Added rolling scan line simulation based on the shader subframe feature. This is implemented with a scrolling scissor rect rather than in the shader itself as this is more efficient although may not work for every shader pass – we may need an option to exclude certain passes. The implementation simply divides the screen up by the number of sub frames and then moves the scissor rect down over the screen over the number of sub frames
UWP: Enable HAVE_ACCESSIBILITY for UWP builds
UWP: Allow UWP build to work with a modified version of Mesa Gallium D3D12
VIDEO: Add subframe shader support for Vulkan/GLcore/DX10-11-12, enabling shaders to run at higher framerate than the content
VIDEO: Fix restoring fullscreen/windowed setting when unloading override
VIDEO/VULKAN: Fix HDR with Vulkan after reinit
VIDEO/VULKAN: Remove the use of oldSwapchain
VIDEO/GL2: Fix OpenGL ES version detection
WEBDAV: Fixed SEGFAULT in WebDav task sync + type changes
WIN32: Fix Alt+Enter not working when menubar is disabled

We added a new core, Dosbox Pure. This brings the total number of available cores on Steam to 65 now.

https://steamproxy.com/steamstore/app/3005610/RetroArch__DOSBox_Pure/

DOSBox Pure is a hard fork of the multiplatform MS-DOS emulator. It was built by Psyraven in 2020 specifically for RetroArch/Libretro and implements advanced features like save states, an on-screen keyboard, highly customizable controller setup or rewinding. DOSBox Pure aims for simplicity and ease of use.

We added a new core, Geolith. This brings the total number of available cores on Steam to 62 now.

Geolith is a highly accurate core for a popular console/arcade system released in the early 1990s, and surviving into the mid 2000s. It is written in modern C and takes a unique approach compared to other emulators for this system. This core focuses on providing a user experience similar to a traditional home console, both by defaulting to home console mode and the use of single-file game files. However, despite this focus, it also maintains full support for playing games in arcade form.

https://steamproxy.com/steamstore/app/2857800/RetroArch__Geolith/

RetroArch 1.17 expands Netplay to support playing multiplayer games that were originally played on two or more separate consoles or computers connected together. This is currently supported by two cores: DOSBox Pure (not available on Steam) and gpSP (available on Steam).

https://steamproxy.com/steamstore/app/1227468/RetroArch__gpSP/

In DOSBox Pure it is now possible to play DOS and early Windows multiplayer games that used IPX, Ethernet or a modem over the internet.

In gpSP, games that support the Wireless Adapter can also benefit from this feature, although only a subset of games work well at the moment. Those curious about more details can read David G.F.’s article about the gpSP implementation here[www.davidgf.net].

In order to use this new functionality just use the regular Netplay menu, where you can host and/or join netplay games. It works seamless with the existing Netplay feature (including lobbies) with no additional settings required. Make sure however, that you use the same or compatible games, since this won’t be automatically enforced.

RetroArch 1.17.0 has just been released.

We also added a new core, PX68K. This brings the total number of available cores on Steam to 61 now.

• AUDIO/PULSEAUDIO: Support device list for PulseAudio
  
• AUDIO/WASAPI: WASAPI Frame Delay fix + cleanups
  
• AUDIO/WASAPI/MIDI: Frame Delay correction
  
• ARCHIVE/ZIP: Improve ZIP decompression This reduces the amount of memory Retroarch needs to extract a ROM file. It will only need the size of the ROM plus 128KiB to extract the file from the ZIP. Previously it needed as much as twice that amount if the compression ratio was not great. This is useful on memory constrained platforms and has no impact on platforms with plenty of memory. Handles all cases correctly (with and without MMAP, for cores that require fullpath or not, small and big ZIP files).
  
• APPLE: Add default keyboard overlay directory to platform_darwin

• FRAMESKIP: Use refresh rate instead of core fps for frameskip timing
  
• INPUT: Combo hold + 'enable_hotkey' correction. Fixed issue with having menu toggle hold combo in different button than 'enable_hotkey', which caused 'enable_hotkey' to also act as menu toggle if held long enough, and simplified and unified duplicate code in start+select holds to a single function.
  
• INPUT: input_keyboard_event: Don't check hotkey binds when device is RETRO_DEVICE_POINTER
  
• INPUT: Add input_keymaps_translate_rk_to_ascii() for correct character input to input_keyboard_event

• INPUT: Send keyboard events for modifiers before other keys (for correct modifier+key input if hitboxes overlap)
  
• INPUT: Remember currently set keyboard mapping bits during same config read, because otherwise customized keybinds can get cleared out of the bits on the next iteration, causing keyboard events to get passed to the core when they should get blocked.
  
• INPUT/AUTOCONFIG: Reinit after updating autoconf profiles
  
• INPUT/LINUX/UDEV: Log mouse devices in info level
  
• INPUT/LINUX/UDEV: First working version of udev driver with touchscreen support and gestures.

• INPUT/OVERLAY: Overlay Caching. Adds overlay_cache_ptr to keep a disabled overlay in memory when it's expected to be shown again. Most input_overlay_deinit calls are replaced with input_overlay_unload, which caches the overlay unless initing/deiniting core or disabling overlays. Loading a cached overlay is done as a swap, intended for osk_toggle.
  
• INPUT/OVERLAY: Add input_overlay_check_mouse_cursor() to preserve show/hide mouse behavior
  
• INPUT/OVERLAY: Don't apply input_overlay_show_mouse_cursor in windowed mode (controlled by mouse grab only)

A new concept we’re going to try, we’ll see if it lasts. Expect irregular blog posts like this, whenever something is on our mind that we want to share. It’s basically like a development diary where we discuss future plans for upcoming versions and what we have been thinking about doing.

Raising the lowest common denominator
RetroArch pushes the concept of backwards compatibility to an absolute extreme. It’s one of our definite pet peeves and something we’re quite proud of. The degree to which we push this is quite irregular in the modern day software industry but we believe it differentiates us from the rest of the pack, and in a good way.

That being the case, recently we believe that in order to improve the out of the box enduser experience, it is perhaps necessary to start making some general baseline assumptions on what endusers realistically are using in terms of hardware. Let’s explain what is behind this idea.

The Steam Mac version was a good opportunity for us to establish some minimum baseline system requirements to make sure that RetroArch on Mac would run well out of the box.

We have some plans for the Windows version which we hope will provide a much better out of the box experience. To learn more about them, read our blog article here[www.libretro.com] on our website.

RetroArch 1.15.0 has just been released.

RetroArch for Mac is now on Steam!

Minimum system requirements:

• Your Mac should be running macOS 10.13 (High Sierra) or later. It is technically possible to try to run it on a version as low as macOS 10.11 (El Capitan), but in order to use it with all features reliably working we’d recommend 10.13 or later.
  
• Your GPU should at least support the Apple Metal 2 graphics API. This is because Vulkan is the default video driver, which in turn relies on MoltenVK. MoltenVK is a Vulkan to Metal abstraction layer which converts Vulkan API calls to Metal. Therefore, a GPU that supports the Metal graphics API is essential for an optimal out of the box experience. Thankfully, most Macs produced in the past 10 years should be able to meet this requirement. If you want to know if your Mac meets the minimum Metal requirements, refer to this page here[support.apple.com]. TLDR – you should be good to go with a Mac that came out mid 2012 or later.

We’re very proud that RetroArch is now available on Steam on all three major OS platforms: Windows, Mac and Linux. Not only that, all but one of the cores (58 as of this writing) are fully compatible.

We went the extra mile and made sure to support both the old and new generation of Macs. Therefore, we support both CPU architectures: Intel x64 based systems and the newer Apple Silicon/ARM architecture. So on newer Apple Silicon Macs you’re getting a native version of RetroArch and any core DLC. No Rosetta2 translation layer overhead in this case.

On top of that, we added two new cores, bringing the total number of available cores on Steam to 59 now.

• CONFIG/INPUT: Unload restores current global config
  
• CONFIG/INPUT/OVERRIDES: Removing a file does not unload current override
  
• CONFIG/INPUT/OVERRIDES: Saving an empty override removes the file if it exists, and won't save when it does not
  
• CONFIG/INPUT/OVERRIDES: Prevent the use of RUNLOOP_FLAG_OVERRIDES_ACTIVE with appendconfig
  
• CORE OPTION: Core option setting type checks. Added checks for getting and setting core option type, since otherwise there will be a crash on close content after browsing to core option categories. Also fixed the no-show switch icon for lone wolf "Lock Installed Core".
  
• CLI: Update selected save slot when start with cli --entryslot
  
• CLI: Decouple config CLI append and config overrides
  
• CLI/MENU/XMB: Stop showing bogus previous icon on CLI launch
  
• D3D9: Fixed display driver scissoring implementation - can now accept 0 width/height
  
• D3D10: Fixed display driver scissoring implementation - can now accept 0 width/height
  
• D3D11: Fixed display driver scissoring implementation - can now accept 0 width/height

• EMSCRIPTEN: Add HAVE_PATCH support for Emscripten
  
• EMSCRIPTEN: Add BSV/Replay support for Emscripten
  
• EMSCRIPTEN: Add command and stdin_cmd features to emscripten RA. update libretro.js to show how commands could be sent over emscripten stdin.
  
• FRAME DELAY/MENU: Show Frame Delay without VSync
  
• GENERAL: Start unpause restriction. Limit the feature using retropad start button to unpause RA to the setting it was made for; "pause on controller disconnect".
  
• GENERAL: Savestate thumbnail aspect ratio fallback. Thanks to at least one certain core that announces aspect ratio as 0, we have to add the same fallback in savestate thumbnails that is happening elsewhere in normal video driver use anyway.
  
• GENERAL: Add support for system subdirs per core/database. Added the trivial and graceful automatic ability to send a different system directory to cores if it exists, for keeping the system dir more sane. First by using the core/library name just like in configs and saves, and then by playlist name, like in thumbnails, and of course default to the current global system dir.
  
• GENERAL: Ignore system subdir replacement if subdir has subdirs.
  
• GENERAL: Restore cached video driver always on quit
  
• LATENCY/PREEMPTIVE FRAMES: Add Preemptive Frames to Latency Settings. RunAhead alternative that reruns core logic to "rewrite history" before the current frame. Frames are only rerun when the controller state changes, so it's faster overall.
  
• LATENCY/PREEMPTIVE FRAMES: Call retro_run before retro_serialize (#14893). Fixes preemptive frames not starting up with a few cores
  
• LOCALIZATION: Updates
  
• LOCALIZATION: Enable localization of video rotation, orientation, and aspect ratio option values.
  
• LOCALIZATION: Mixer stream localization also added
  
• LOCALIZATION/MENU/HELP: Context dependent help text for audio and video drivers. Language corrections
  
• LOCALIZATION/MENU/LANGUAGE: Language submenu now shows the progress of translated strings for each language.
  
• LOCALIZATION: Help texts now localizable through Crowdin.
  
• LIBRETRO: Enable RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME for libretro-video-processor
  
• LIBRETRO/HW: Add GET_HW_CONTEXT_NEGOTIATION_INTERFACE_SUPPORT. Works around issues in v1 interface where it was not possible to query what frontend would do when faces with newer interface versions. This env-call gives stronger guarantees how things have to work.
  
• INPUT: Allowing keyboard hotkeys to work without hotkey modifier if modifier is only mapped to RetroPad
  
• INPUT: Allowing keyboard hotkey keys for typing if hotkey modifier is set to keyboard but not pressed
  
• INPUT: Allowing keyboard RetroPad keys for typing if emulated device type is "None"
  
• INPUT/BLUETOOTH: Fix a crash in for BT HID devices. (#14922) pad_connection_destroy() frees slots, no need to free it again.
  
• INPUT/BSV/REPLAY: Don't start video recording when BSV recording starts
  
• INPUT/BSV/REPLAY: Don't double-record inputs in BSV recording
  
• INPUT/BSV/REPLAY: Don't autoload states if a BSV file is being played back or recorded
  
• INPUT/BSV/REPLAY: Moved BSV initialization before autoload code
  
• INPUT/BSV/REPLAY: Don't trigger autoload code if there is bsv movie state
  
• INPUT/BSV/REPLAY: Allow for both -e and -R to start a BSV file recording at a state
  
• INPUT/BSV/REPLAY: Add keyboard recording support to BSV
  
• INPUT/BSV/REPLAY: Fix BSV playback from a starting state for DOSbox
  
• INPUT/BSV/REPLAY: Associate states with replays. Now states can be saved and loaded during replay recording and playback in a way that keeps the integrity of the recording. Recordings also have a (moderately) unique identifier associated with them.
  
• INPUT/BSV/REPLAY: Add checkpointing feature for replay recordings. If cores are not deterministic, or if they only have bounded determinism, we can obtain less drift if replay files also contain periodic checkpoint states. These are configured by the new retroarch setting replay_checkpoint_interval (measured in seconds). States are inserted into the replay file in between frames. This also fixes the settings display for the replay autoincrement max keep setting.
  
• INPUT/FRAMEADVANCE: Use non-rendering pause mode when frameadvance is triggered
  
• INPUT/HOTKEYS/OVERLAYS: Do not block input overlay hotkeys
  
• INPUT/HOTKEYS: Hotkey blocking correction. Turned out the previous hotkey blocking changes worked properly only with winraw driver and not the rest (at least with Windows), because input_keyboard_event() could be called at the wrong moment, and thus storing keyboard menu press there broke the separation of controller Guide menu button and keyboard menu key. Also allowed the blocking to work in both directions so that controller hotkeys won't get blocked if only keyboard has "enable_hotkey" bind.
  
• INPUT/LINUX/UDEV: Fix udev guns input when id_mouse is not id_joystick
  
• MENU: Rename 'Standalone Cores' to 'Contentless Cores'
  
• MENU: Music files should also obey builtin_mediaplayer_enable (#14967) Disabling the built in media player should be possible for music files as well. Without this, sound files can not be opened from file browser with cores that support them.
  
• MENU: Relocated items to a more logical order
  
• MENU: Corrected some title capitalizations (when/before/after are not low case, but for/the/a are)
  
• MENU/AUDIO: Add dropdown menu for audio device
  
• MENU/HELP: Help for turbo modes (#14919). Help text added for each of the selectable turbo modes.
  
• MENU/INPUT: Add unified back action to all menu drivers. Usability boost for all menu drivers resulting in similar behavior as with Ozone currently, which is pressing back/cancel enough the selection jumps first to Main Menu and when pressed again jumps to the first item, so that when a core is running, Quick Menu is very quickly accessible from anywhere. And when core is not running, the first item would be Load Core.
  
• MENU/INPUT: Override bind save + menu manager overhaul
  
• MENU/INPUT: Allowed and fixed input bind saving to overrides
  
• MENU/INPUT: Overhauled override menu
  
• MENU/INPUT: Pressing Start on the top active file entry reloads current overrides as startup would
  
• MENU/SUBLABELS: All under "Configuration File" + moved "Reset to Defaults" to bottom
  
• MENU/SUBLABELS: Quick Menu > Controls > Port x Controls
  
• MENU/SUBLABELS: Port x Controls > Device Type
  
• MENU/RGUI: Fix disabled menu item color. The effect was not working properly, since transparency meant using the core output color as background.
  
• MENU/XMB: Fixed playlist manager icons to take Explore Views into account properly
  
• MENU/XMB: Changed XMB Explore View title to match Ozone
  
• MENU/XMB: Added "Switch Icons" option
  
• MENU/XMB: Fix MENU_ACTION_CANCEL when search is active. Nasty issue discovered in XMB which broke search term cancelation.
  
• MENU/XMB: Layout corrections:
  
• MENU/XMB: More room for longer item labels and values
  
• MENU/XMB: "Core Downloader" has extra space for item and "installed" indicator
  
• MENU/XMB: Fixed "Menu Scale Factor" to not require restarting to get the actual end result
  
• MENU/XMB: Adjusted scale factor to behave better with both layouts
  
• MENU/XMB: Fixed savestate thumbnails and adjusted vertical fade factor in "Handheld" layout
  
• MENU/XMB: Changed thumbnail shadow to outline and tightened fullscreen thumbnail margins
  
• MENU/XMB: Adjusted global shadow opacity
  
• MENU/XMB: Remove "Framebuffer opacity" from XMB as it does not use it. Also, rename the corresponding menu title, since "framebuffer" is not that intuitive.
  
• MENU/OZONE: Fixed playlist manager icons to take Explore Views into account properly
  
• MENU/OZONE: Refresh thumbnail on close content hotkey
  
• MENU/OZONE: Ozone footer enhancements (#14926). Add Help button (Select) and Reset to Default (Start) to footer where applicable.
  
• MENU/OZONE: Ozone footer enhancements (#14934). Display Help footer only if there is actual info to be displayed, either actual help, or sublabel if it is not visible otherwise.
  
• MENU/OZONE: Ozone footer enhancement: Scan button (#14949). Display Scan button in footer when it is applicable.
  
• MENU/OZONE: Add Clear button to Ozone footer (#14947). Add indication of Clear button when it is applicable (currently: keybinds).
  
• MENU/MATERIALUI: Added missing Favorites+History icons in playlist manager
  
• MENU/MATERIALUI: Added "Switch Icons" option
  
• MENU/CHEATS: Added missing icons in cheats (Delete + Copy After/Before)
  
• MENU/CHEATS: Fixed label capitalization in cheats (Add New After/Before This)
  
• MENU/SOUNDS: Add scrolling sounds for RGUI, XMB, MaterialUI and Ozone.
  
• MENU/SOUNDS: Better scrolling sound implementation, add new 'notice back' sound
  
• MENU/SOUNDS: Scroll sound fixes. Correctly get list size in xmb.c for playing scrolling sound when switching categories, play the scrolling sound when pressing cancel in ozone, play the sound when scrolling with ZL and ZR, play the correct sound when scrolling with L- MIYOO: L3/R3 support for Dingux Gamepad controller device.
  
• MENU/WIDGETS: Show square sized widget on volume mute. Volume widget is currently fixed size always, and thus showing a lot of empty space when muting, therefore shorten the box to icon size only when muting.
  
• NETWORKING: Call ssl_socket_close for SSL sockets
  
• NETWORKING/CHEEVOS: net_http - Temporary fix for cheevos crash. Don't use new timeout/poll code for cheevos HTTP requests.
  
• NETWORKING/MENU: Network information cleanup:
  
• NETWORKING/MENU: Remove extra space from : delimiter
  
• NETWORKING/MENU: Trim useless/duplicate garbage from the end of ipv6 address. Windows shows %[adapter number], Linux shows %[adapter name], which already shows before the address
  
• NETWORKING/STDIN: Add LOAD_STATE_SLOT N command to stdin/network protocol
  
• OSD/STATISTICS: Add Run-Ahead data to on-screen statistics
  
• OSX/MACOS: Steam platform support
  
• OSX/MACOS: Set LSApplicationCategoryType to games
  
• OSX/MACOS: Include OpenGL video driver on Metal macOS builds (10.13 and higher)
  
• OSX/MACOS: Fix a few mac windowed mode settings -
  
• OSX/MACOS: Use "Remember window position and size" setting (fixes #14806)
  
• OSX/MACOS: Implement window opacity
  
• OSX/MACOS: Enable "Show window decorations" toggle
  
• OSX/MACOS: Hide "Disable composition" option (osx does not support disabling composition)
  
• OSX/MACOS: Make sure to use the file system path name, not the URL name
  
• OSX/MACOS/IOHIDMANAGER: Various memory access fixes to prevent crashes (#14459) (#15000). Prevent double free and null dereference when the controller is quickly reconnected. Handle error when controller device query returns null instead of crashing.
  
• OSX/MACOS/METAL BUILD: Fix input events (keyboard/mouse) sometimes going lost when switching between fullscreen and windowed mode. Fixes lots of longstanding issues
  
• OSX/MACOS/OPENGL: Fix for fullscreen OpenGL driver in Metal macOS build
  
• OSX/MACOS/VULKAN/MOLTENVK: Default to Vulkan driver when available (for 10.13 Metal Universal build)
  
• OSX/MACOS/VULKAN/MOLTENVK: Updated Vulkan on Metal for OSX via MoltenVK
  
• OSX/MACOS/VULKAN/MOLTENVK/HDR: Fix non-HDR colors
  
• OSX/MACOS/SLANG: The change to apply shaders would be executed and then a command to apply shaders would immeidately be enqueued, to run asynchronously after the current event handler, which then did exactly the same. Fixes issue #14789 - Turning on shaders on Metal build 1.14.0 stable for Mac OS will slow emulation drastically thing, creating a busy loop.
  
• RECORDING: Add recordings to video history playlist
  
• REWIND: Don't take rewind steps while menu pause active
  
• RUNLOOP: Currently when core is paused, video output will be stopped completely too, making it impossible to animate widgets while paused, therefore:
  
• RUNLOOP: Added a new runloop state for pause which renders last cached frame
  
• RUNLOOP: Allowed rewinding while paused so that it acts like backwards frameadvance. Also moved rewind step taking before menu iteration so that steps won't be lost while in menu when menu_pause is disabled
  
• RUNLOOP: State load and reset while paused will forget pause for x frames in order to show proper output
  
• RUNLOOP: Allowed reading pause hotkey while menu is active
  
• RUNLOOP: Allowed reading screenshot hotkey while menu is active
  
• RUNLOOP: Joined 2 fullscreen hotkey checks to one (Any ideas why they were separated for paused and non-paused states, since one works fine for both..?)
  
• RUNLOOP: Implement GET_HW_CONTEXT_NEGOTIATION_INTERFACE_SUPPORT. Fairly trivial. Just report the latest version.
  
• SAVESTATES: State slot hotkey adjustments -
  
• SAVESTATES: Allow selecting -1 Auto slot with hotkeys
  
• SAVESTATES: Allow wrap-around from -1 to 999 and backwards
  
• SAVESTATES: Show failure message when trying to load a state that does not exist instead of plain "Loading state"
  
• SAVESTATES: Shorten the duration of slot change notification
  
• SAVESTATES: Change the widget type to the same type as shader toggle for better back and forth action. Closes [Widgets] Save state slot switcher
  
• SHADERS: Append Preset feature
  
• SHADERS: Prepend Preset feature
  
• SHADERS: Shader Preset - Wildcard Replacement in Paths on Load. When a simple preset loads, text wildcards which are found in paths inside the presets will be replaced with values coming from the current RetroArch context. The replacement will be executed on both texture paths and reference paths.
  
• SHADERS/SLANG/SPIRVCROSS: Update to latest SPIRV-Cross, fixing Metal shader compilation issues along the way
  
• VIDEO: Allow manual video swap interval forcing. The addition of auto swap interval effectively prevented manual forcing, which is beneficial when the rate is not reported properly. Therefore use the interval in the calculation only when using automatic interval.
  
• VULKAN: Fix crash when using multiple physical devices and HW core (#14889)
  
• VULKAN: Detect if wrong PhysicalDevice is returned.
  
• VULKAN: Actually query physical device before creating core device.
  
• VULKAN: Define and implement v2 of context negotiation interface
  
• VULKAN: Add v2 of context negotiation interface.
  
• VULKAN: Add vkEnumerateInstanceVersion symbol.
  
• VULKAN: Implement v2 context negotiation
  
• VULKAN: Use compute shaders to upload RGB565
  
• VULKAN: Fix regression with RGB565 and OriginalHistory.
  
• VULKAN/WAYLAND: Don't clamp the number of requested images. Due to an unfortunate "feature", MESA always reports 4 as the Vulkan surface's minImageCount in Wayland. However, values of 2 and 3 work perfectly well, even if they are out of spec, providing way better latencies when using the Vulkan backend on Wayland. So this removes the artificial clamping that was being done to desired_swapchain_images, because it's not really necessary and was causing very noticeable input lag on Wayland+Vulkan.
  
• VULKAN/MENU/RGUI: Fix RGUI on Vulkan on platforms that don't have _pack16 VkFormats
  
• VULKAN/MACOS/OSX: avoid using _PACK16 pixel formats on platforms without them
  
• WAYLAND: On scaled desktops the wayland backend deciding to resize based on values multiplied by the scale factor twice. Resulting in continuous attempts to rebuild the swapchain when in fullscreen.
  
• WAYLAND: Wait for splash screen configuration. Before, configuration (resize) events for the initial wayland window could happen before or after set_video_mode which could result in a small or corrupted window. Now we make sure that the initial window has processed it's resize events before window size is set by set_video_mode.
  
• WAYLAND: Changes the initial window to show a RetroArch logo copied from the icon of the X11 backend.
  
• WAYLAND: Build pointer-constraints and relative-pointer protocols.
  
• WAYLAND/GL: GL is sometimes not rescaling property (Super + Left).
  
• WIN32/INPUT: Add support for mouse button swap
  
• WIN32: Fix keyboard event characters. Added sending key chars to all input drivers (currently they only send scan codes), and also missing mods for raw.
  
• WIN32: Fix restart if path has spaces. CreateProcess does not like to have anything executable path related in the second parameter lpCommandLine if the path has spaces. Thus strip everything from args except the actual parameters.
