AUDIO: Memalign audio buffers to 64 bytes. This is the most common cache line size, helps with performance. Also fixes issues with platforms like PSP that wrongly assume that malloc returns aligned buffers (to 16bytes). This recently broke the PSP builds
AUDIO/ALSA: Fix float format detection
AUDIO/JACK: Deinterleave in the process callback. This allows us to avoid the extra copy to the deinterleave buffer and lets us use only a single jack ringbuffer
AUDIO/JACK: (Audio/JACK) Fix non-blocking write. Previously we would wait on the condition variable even in the non-blocking case. This improves fast-forward performance massively and brings JACK in line with other backends in that regard

OGA: Fix messages from not disappearing
OGA: Implement RETRO_ENVIRONMENT_GET_CURRENT_SOFTWARE_FRAMEBUFFER. This is a faster rendering codepath for software rendered libretro cores that some libretro cores use right now. Video drivers in RetroArch have to explicitly implement this for this codepath to work at runtime.
OPENDINGUX: Add/Optimise rumble interface
OPENDINGUX: Fix frozen video when enabling fast forward
OPENDINGUX/SDL: OSD font clean-up
OPENDINGUX/SDL: Enable selection of image interpolation method when using 'sdl_dingux' gfx driver
OPENDINGUX/SDL: Enable integer scaling when using the 'sdl_dingux' gfx driver
OVERLAYS: Add option to scale overlays automatically (with aspect ratio correction)
OVERLAYS: Hide Overlay When Gamepad is Connected. Overlays will be hidden automatically when a gamepad is connected in port 1, and shown again when the gamepad is disconnected.
OVERLAYS: New default overlays for mobile (neo-retropad)
OVERLAYS: In addition to overlay scale, the user can now set an Overlay Aspect Adjustment factor. Most overlays are designed for 16:9 displays, which means they become stretched/ugly on modern wide aspect phones and suchlike. By changing the Overlay Aspect Adjustment factor, a user can scale the overlay width/height to achieve a uniform appearance regardless of display resolution.
OVERLAYS/FIX: The Overlay X Offset and Overlay Y Offset options have been fixed, and now work correctly
OVERLAYS/FIX: All of the above options (and Overlay Scale) are configured and saved independently for landscape and portrait display orientations – so adjusting everything for a nice landscape layout won't break the portrait display
OVERLAYS/FIX: When using the Vulkan gfx driver, memory is leaked every time an overlay is freed
OVERLAYS/FIX: When threaded video is enabled, loading overlays with no images (i.e. utility-type overlays, where everything is hidden until the screen is touched) can generate segfaults due to improper usage of realloc()
OVERLAYS/FIX: When Show Inputs on Overlay is enabled, ASAN reports bit shift errors due to an incorrect range check when handling turbo inputs – essentially, there is no upper limit to the considered input id range, which means overlay hotkeys (menu toggle, etc.) are incorrectly treated as having turbo support, causing bit shifts using wildly inappropriate id indices
PLAYLISTS/PORTABLE: Fixed first load initialization
REWIND: Prevent 'Rewind Frames' from being set to '1' incorrectly on load content
RUNAHEAD: Add Run-Ahead Toggle hotkey with notifications
RBUF/ANIMATIONS: Simplify gfx_animation by switching from dynarray to rbuf

VIDEO FILTERS: Add 'Upscale_256x-320×240' video filter
VIDEO FILTERS: Add 'Upscale1.5x' video filter
WIFI/LAKKA: Add a proper WiFi menu, with Enable/Disable and Disconnect options. This also allows WiFi passwords to be remembered. The underlying tool (connman) allows to store passswords (that's why it auto connects whenever you boot a Lakka device), so we expose this so that the user does not have to re-input the pass when connecting to a saved wifi.

https://www.libretro.com/index.php/retroarch-1-9-0-released/

AUTOCONFIG: Ensure correct directory is used when saving autoconfig profiles
BLUETOOTH: Add a Bluetooth driver (Lakka-only for now)

CHEEVOS: Hash buffered data when available
CHEEVOS: Fix Auto Save State freezes RetroArch while Cheevos is enabled
CORE OPTIONS: Pressing OK (or clicking/tapping) on a boolean toggle core option no longer opens a drop-down list. The value now toggles directly, just like boolean options everywhere else in the menu
CORE OPTIONS: Toggling an option that changes the number of core options being displayed (i.e. things like `Show Advanced Audio/Video Settings) no longer resets the navigation pointer to the start of the list
CORE OPTIONS: Before, RetroArch would identify core option values as being boolean if they had labels matching the specific strings enabled or disabled. Most core devs would abide by this, but not always... As a result, we sometimes would end up with misidentified values, with all kinds of Enabled, Off, True, etc. strings littering the menu, in place of proper toggle switches. All boolean-type value labels are now detected, and replaced with standard ON/OFF strings.
CLI: A new command line option --load-menu-on-error has been added
CRT: On the fly CRT porch adjuments - these changes allow a user to adjust how the porch algorithm generates the 15khz/31khz output. Giving the ability to change over/under scan.

PLAYLISTS: Playlist base content directory paths - portable playlists
PLAYLISTS/SEARCH: Enhanced playlist search functionality
PLAYLISTS/DATABASE: Add Explore view

https://www.libretro.com/index.php/retroarch-1-8-9-released/

AUTO SAVESTATES: Ensure save states are correctly flushed to disk when quitting RetroArch (fixes broken save states when exiting RetroArch - without first closing content - with 'Auto Save State' enabled)
BUILTIN CORES: Builtin cores like ffmpeg and imageviewer would previously try to erroneously load a dynamic core named 'builtin' - this would fail and would just be a wasteful operation - this now skips dylib loading in libretro_get_system_info for builtin cores
CHEEVOS: Report API errors when unlocking achievements or submitting leaderboards
CHEEVOS: Support less common file extensions
CHEEVOS: Disable hardcore mode when playing BSV file
CHEEVOS: Correctly report unlocked non-hardcore achievements when hardcore is paused

DISK CONTROL: Cycle Disk Tray now becomes Eject Disk or Insert Disk depending upon current drive state
DISK CONTROL: Current Disk Index is only shown when the current disk has been ejected
DISK CONTROL: The old Insert Disk entry has been changed to Load New Disk, and is only shown when a disk is currently inserted (this is because loading a new disk from the filesystem - i.e. bypassing the m3u playlist disk index interface - automatically ejects and inserts disks, and so cannot be done while the virtual drive is empty)

MENU/USABILITY: Add Audio -> Resampler settings.
MENU/USABILITY: Add Audio -> Output and Audio -> Synchronization.
OPENGL: Shaders are now working properly (only in OpenGL) when rotating both from Core API rotation and from menu video rotation. The fix is clearly visible with crt-royale for example.
OPENGL: 1:1 PAR is now correct when rotating (both from Core API rotation and from menu video rotation, as you said, in the latter case you currently have to change Aspect Ratio after menu video rotation for it to work).
OPENGL: When using Custom Aspect Ratio and rotation (both from Core API rotation and from menu video rotation), Integer Scaling is now working properly (correct multiples of internal resolution). Even when Integer Scaling is not activated, the Custom AR width / height are now correctly labeled using (1x), (2x), ... suffixes. You also have to activate Integer Scaling after menu video rotation for it to work.
OPENGL: For all other Aspect Ratio options, Integer Scaling and rotation (both from Core API rotation and from menu video rotation) are now working properly together (correct multiples of internal resolution). You also have to activate Integer Scaling after menu video rotation for it to work.

VIDEO: Support DRC even when using a vsync swap interval higher than 1.
VIDEO LAYOUT: Fixed XML parsing of attributes with spaces, should fix issues with several video layouts.
VULKAN/ANDROID: Workaround weird WSI return codes in landscape mode - Android WSI wants you to use preTransform, and if it is not used correctly, Android 10 will return VK_SUBOPTIMAL_KHR, and we would create a new swapchain every frame. This workaround just ignores this error, since it's not really an error. A more "proper" fix is to use prerotate and modify the MVP matrices, which might help certain devices with crummy display processors.
VULKAN/ANDROID: Recreate swapchain on orientation change. ANativeWindow getWidth/Height does not detect any changes when using Vulkan, so use the old onContentRectChanged callback to get notified when size changed. Use those values instead when figuring out how large swapchain to create.
