 # Future
 
+# 1.22.1
+- ANDROID: OnNewIntent handler to allow launchers start new content without closing first
+- ANDROID: Use app-specific storage for Google Play builds of RetroArch
+- ANDROID: Implement support for the Storage Access Framework, to allow the user to mount most directories1 from internal storage, the SD card, other removable storage devices and any document providers provided by other Android apps on the current device.
+- 3DS: Add 800px mode for New 3DS models
+- APPLE: Include sameduck, gearcoleco, geargrafx cores in App Store builds
+- APPLE: Include reminiscence, virtualjaguar, vitaquake2 cores in App Store builds
+- APPLE: Include gam4980 core in App Store builds
+- APPLE: Bundle identifier added to Information menu
+- APPLE: Option to control the usage of Metal argument buffers
+- APPLE: Don't force fullscreen, allow multitasking on iPad
+- APPLE: AppIntents for Siri, Shortcuts
+- APPLE: Fix ffmpeg camera driver
+- APPLE/MFI: Try harder to own the home button
+- AUDIO: Microphone CoreAudio driver for iOS and macOS
+- AUTOCONF: Autoconfig match extended with a physical identifier
+- CAMERA: Use ffmpeg libavfilter virtual input device as default
+- CHEEVOS: Show additional message for unsupported achievements
+- CHEEVOS: Upgrade to rcheevos 12.1
+- CHEEVOS: Change expired token message from info to error
+- CHEEVOS: Hashing of RVZ files is now supported
+- CLOUDSYNC: Enable icloud_drive cloud sync backend on MacOS / iOS
+- CLOUDSYNC: Don't always trust the server hash
+- CLOUDSYNC: Enable WebDAV support for Android
+- CLOUDSYNC: Speed up cloudsync on Apple
+- DATABASE: Improve multidisk game scanning
+- DATABASE: Filter in Database Manager now works for genre and region
+- EMSCRIPTEN: Support core switching
+- EMSCRIPTEN: Support suspend screensaver
+- EMSCRIPTEN/RWEBCAM: Fix camera driver
+- EMSCRIPTEN/RWEBINPUT: Add accelerometer/gyroscope support
+- EMSCRIPTEN/RWEBPAD: Add rumble support
+- EMSCRIPTEN/RWEBAUDIO: Rewrite driver, set as default audio driver
+- INPUT: Default key and mouse binds for lightgun Start and Select buttons
+- INPUT: Turbo mode corrections
+- INPUT: Turbo fire settings are now saved to remaps, not to overrides
+- INPUT: Fix menu usage when OK/Cancel has mouse binds
+- INPUT: Ignore menu mouse startup position before moving
+- INPUT: Fix heavy slowdown when using Bluetooth XInput controllers with rumble
+- INPUT: Reset and close content hotkeys now require confirmation, similar to quit
+- INPUT: Menu toggle and hotkey enable can now be assigned to the same key
+- INPUT: Option to have hotkeys follow the port mapped first to the core
+- INPUT/ANDROID: Favor mouse coordinates for lightgun
+- INPUT/UDEV: Fix lost terminal settings after restart from menu
+- INPUT/BSV/REPLAY: Bumped replay format version to 2. Old replays will still play back fine.
+- INPUT/BSV/REPLAY: Add option to skip deserializing checkpoints from replay files (it introduces jank in some emulators).
+- INPUT/BSV/REPLAY: Add checkpoint and initial savestate compression, following the `savestate_file_compression` config boolean.  Use zstd if available, or fall back to zlib.
+- INPUT/BSV/REPLAY: Add incremental checkpoints based on statestreams (depending on `HAVE_STATESTREAM` compile time flag).  As an example, 60 `pcsx_rearmed` savestates would take 267MB uncompressed; with incremental encoding this is reduced to 77MB.  Compressing the result can reduce the size to just 4MB.
+- INPUT/BSV/REPLAY: Checkpoint compression and encoding can be combined. For example, 60 `pcsx_rearmed` checkpoints can take up just 15MB if each state is incremental and compressed. This is not as optimal as using incremental states without save state compression followed by offline compression, but is a good compromise in many use cases.
+- INPUT/BSV/REPLAY: Add hotkeys and text commands to force a checkpoint insertion into the currently recording replay, and to seek backwards to the previous checkpoint and forwards to the next checkpoint.
+- INPUT/BSV/REPLAY: Add a text command to seek to a specific frame of the currently playing/recording replay; it will return via the command replier the actual seeked-to frame (right now it only supports seeking to checkpoints).

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.

-Struct ordering
----------------
-
-For POD-types, try to order structs as follows (first to last):
-
-   * long double     (8 bytes, 16 bytes [64bit x86], 12 bytes [32bit x86])
-   * double          (8 bytes)
-   * int64_t         (8 bytes,         8 bytes [32bit ARM], 
-                      4 bytes [32bit x86])
-   * uint64_t        (4 bytes [32bit], 8 bytes [32bit ARM], 8 bytes [64bit])
-   * pointer         (4 bytes [32bit], 8 bytes [64bit] [1])
-   * intptr_t        (4 bytes [32bit], 8 bytes [64bit] [1])
-   * uintptr_t       (4 bytes [32bit], 8 bytes [64bit] [1])
-   * ptrdiff_t       (4 bytes [32bit], 8 bytes [64bit] [1])
-   * ssize_t         (4 bytes [32bit], 8 bytes [64bit])
-   * size_t          (4 bytes [32bit], 8 bytes [64bit])
-   * jmp_buf         (4 bytes)
-   * long            (4 bytes [64bit Win], 8 bytes [64bit non-Win], 
-                      4 bytes [32bit])
-   * int32_t         (4 bytes)
-   * unsigned        (4 bytes)
-   * float           (4 bytes)
-   * int             (4 bytes)
-   * enum            (4 bytes)
-   * int16_t         (2 bytes)
-   * char            (1 byte)
-   * bool            (1 byte)
-
-   [1] PS3 uses 4 byte pointers despite having a 64bit processor
-
-   Struct members should be sorted by alignment. Therefore, structs
-   should be sorted by the largest type inside them.
-
-   For example, take a struct like this:
-
-   typedef struct
-   {
-      size_t capacity;
-      bool old_format;
-      bool compress;
-      bool fuzzy_archive_match;
-      bool autofix_paths;   
-      char path[PATH_MAX_LENGTH];
-      char base_content_directory[PATH_MAX_LENGTH];
-   } playlist_config_t;
-
-size_t has the biggest alignment here, so 'struct playlist_config_t' 
-inside a struct should come before or after size_t.
-
-*** 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.
-
-Example:
-
-   struct a
-   {
-      char* b;
-      size_t b_len;
-      char* c;
-      size_t c_len;
-   };
-
-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]. 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.
-
-Miscellaneous
--------------
-- Brace usage follows "Allman style". The brace associated with a control statement is placed on the following line, 
-  indented to the same level as the control statement. 
-  Statements within the braces are indented to the next level.
-- A single statement block must not include brackets (unless the block uses a macro that expands into multiple lines)
-- If possible, avoid 'while (true)' and use 'for (;;)' instead

+# Security Policy
+
+## Reasonable expectations
+
+RetroArch is a frontend for the libretro API. The main functionality is fulfilled by invoking other binary libraries ("cores") which are not restricted by RetroArch in any way. Cores are able to read/write/delete files, spawn processes, communicate over the network. Also, source for cores is not necessarily in control by libretro team, and core binaries / RetroArch binaries are not signed. For this reason, it is a bad idea to use RetroArch or any other libretro frontend on security critical systems.
+
+Also, RetroArch and cores have been packaged in several ways. Content on the [official download site](https://buildbot.libretro.com/) is built from a direct mirror of the original RetroArch and core repositories, no binaries are reused. Note that source for the core repositories may be outside libretro team control.
+
+## Supported Versions
+
+For most delivery channels, libretro team does not have control over the version. The exceptions are:
+- [official download site](https://buildbot.libretro.com/)
+- Steam release
+- Apple App Store release
+- various Android app store releases
+- note that Google Play Store version is years behind and can not be updated
+
+You may report vulnerability against any recent version, but be reasonable.
+
+## Reporting a Vulnerability
+
+Please report security vulnerabilities at libretro@gmail.com
+
+## Possible remediation
+
+Due to the variety of delivery channels, RetroArch team can not recall any given version universally. Security fixes are accepted for next release, and notice may be posted in the channels controlled by RetroArch team, depending on the severity assessed by RetroArch team.

 /*
-   Invoke this method to send a request to the AI service.
-   It makes the following POST request using URL params:
-      – source_lang (optional): language code of the content currently running.
-      – target_lang (optional): language of the content to return.
-      – output: comma-separated list of formats that must be provided by the
-         service. Also lists supported sub-formats.
+   This function does all the stuff needed to translate the game screen,
+   using the URL given in the settings.  Once the image from the frame
+   buffer is sent to the server, the callback will write the translated
+   image to the screen.
 
-   The currently supported formats are:
-      – sound: raw audio to playback. (wav)
-      – text: text to be read through internal text-to-speech capabilities.
-         'subs' can be specified on top of that to explain that we are looking
-         for short text response in the manner of subtitles.
-      – image: image to display on top of the video feed. Widgets will be used
-         first if possible, otherwise we'll try to draw it directly on the
-         video buffer. (bmp, png, png-a) [All in 24-bits BGR formats]
+   Supported client/services (thus far)
+   -VGTranslate client ( www.gitlab.com/spherebeaker/vg_translate )
+   -Ztranslate client/service ( www.ztranslate.net/docs/service )
 
-   In addition, the request contains a JSON payload, formatted as such:
-      – image: captured frame from the currently running content (in base64).
-      – format: format of the captured frame ("png", or "bmp").
-      – coords: array describing the coordinates of the image within the
-         viewport space (x, y, width, height).
-      – viewport: array describing the size of the viewport (width, height).
-      – label: a text string describing the content (<system id>__<content id>).
-      – state: a JSON object describing the state of the frontend, containing:
-         – paused: 1 if the content has been paused, 0 otherwise.
-         – <key>: the name of a retropad input, valued 1 if pressed.
-            (a, b, x, y, l, r, l2, r2, l3, r3)
-            (up, down, left, right, start, select)
+   To use a client, download the relevant code/release, configure
+   them, and run them on your local machine, or network.  Set the
+   retroarch configuration to point to your local client (usually
+   listening on localhost:4404 ) and enable translation service.
 
-   The translation component then expects a response from the AI service in the
-   form of a JSON payload, formatted as such:
-      – image: base64 representation of an image in a supported format.
-      – sound: base64 representation of a sound byte in a supported format.
-      – text: results from the service as a string.
-      – text_position: hint for the position of the text when the service is
-         running in text mode (ie subtitles). Position is a number,
-         1 for Bottom or 2 for Top (defaults to bottom).
-      – press: a list of retropad input to forcibly press. On top of the
-         expected keys (cf. 'state' above) values 'pause' and 'unpause' can be
-         specified to control the flow of the content.
-      – error: any error encountered with the request.
-      – auto: either 'auto' or 'continue' to control automatic requests.
+   If you don't want to run a client, you can also use a service,
+   which is basically like someone running a client for you.  The
+   downside here is that your retroarch device will have to have
+   an internet connection, and you may have to sign up for it.
 
-   All fields are optional, but at least one of them must be present.
-   If 'error' is set, the error is shown to the user and everything else is
-   ignored, even 'auto' settings.
+   To make your own server, it must listen for a POST request, which
+   will consist of a JSON body, with the "image" field as a base64
+   encoded string of a 24bit-BMP/PNG that the will be translated.
+   The server must output the translated image in the form of a
+   JSON body, with the "image" field also as a base64 encoded
+   24bit-BMP, or as an alpha channel png.
 
-   With 'auto' on 'auto', RetroArch will automatically send a new request
-   (with a minimum delay enforced by uints.ai_service_poll_delay), with a value
-   of 'continue', RetroArch will ignore the returned content and skip to the
-   next automatic request. This allows the service to specify that the returned
-   content is the same as the one previously sent, so RetroArch does not need to
-   update its display unless necessary. With 'continue' the service *must*
-   still send the content, as we may need to display it if the user paused the
-   AI service for instance.
-
-   {paused} boolean is passed in to indicate if the current call was made
-   during a paused frame. Due to how the menu widgets work, if the AI service
-   is called in 'auto' mode, then this call will be made while the menu widgets
-   unpause the core for a frame to update the on-screen widgets. To tell the AI
-   service what the pause mode is honestly, we store the runloop_paused
-   variable from before the service wipes the widgets, and pass that in here.
