gbe_fork/CHANGELOG.md

* **[Clompress]** corrected Turkish translation

---

* **[breaking]** move some settings inside a new file `config.ini` which could be created inside the `steam_settings` folder, or inside the global settings folder, which is located at `%appdata%\Goldberg SteamEmu Saves\settings\` on Windows for example.  
  you can create a global `.ini` file `Goldberg SteamEmu Saves/settings/config.ini` for the common options, and another local one `steam_settings/config.ini` for the game-specific options, and the emu will merge them.

---

* **[breaking]** changed the environment variable `SteamAppPath` to `GseAppPath`, which is used to override the program path detected by the emu
* allow changing the name of the base folder used to store save data, by default it would be `Goldberg SteamEmu Saves`, suggested by **[Clompress]**  
  this could be changed by setting the option `saves_folder_name` inside the local file `steam_settings/config.ini`, the global one will not work
* allow creating the file `local_save.txt` inside the `steam_settings` folder
* increase run callbacks background thread polling time to `~200ms`
* changed the overlay title to give proper credits to its author
* set these env vars for a more accurate emulation:
  - `SteamAppUser`
  - `SteamUser`
  - `SteamClientLaunch`
  - `SteamEnv`
  - `SteamPath`

 ---
 
## 2024/4/11 (2)

* **[Clompress]** Turkish translation for the overlay
* added callbacks alongside call results in various interfaces, allowing some games to work properly
* trigger additional `UserAchievementStored_t` callbacks in `Steam_User_Stats::StoreStats()` for all the unlocked achievements prior to calling this function
* trigger `UserStatsStored_t` callback in `Steam_User_Stats::IndicateAchievementProgress()` instead of a call result (call result is removed),
  might break stuff
* trigger `UserStatsReceived_t` callback as well as call result in `Steam_User_Stats::RequestUserStats()`, needed by some games
* trigger additional `PersonaStateChange_t` callback in `Steam_Friends::SetPersonaName()`
* trigger `SteamInventoryRequestPricesResult_t` callback as well as call result in `Steam_Inventory::RequestPrices()`
* trigger `SteamUGCQueryCompleted_t` callback as well as call result in `Steam_UGC::SendQueryUGCRequest()`
* trigger callback as well as call result in many places including the following classes:
  - `Steam_User_Stats`
  - `Steam_HTTP`
  - `Steam_HTMLsurface`

---

## 2024/4/11

* **[breaking]** load overlay audio from `sounds` subfolder, either from the local game settings folder `steam_settings/sounds`,  
  or from the global settings folder `Goldberg SteamEmu Settings/settings/sounds`
* allow loading the overlay fonts from the global settings folder `Goldberg SteamEmu Settings/settings/fonts`
* added missing example overlay `.wav` file
* updated readme files + added some which were missing + removed invalid avatar example

---

## 2024/4/10

* properly implement `Steam_Apps::GetAvailableGameLanguages()`
* ensure current emu language is inside `supported_languages` list
* run the callbacks background thread earlier inside `Steam_Client::ConnectToGlobalUser()`  
  since some games don't call `SteamAPI_RunCallbacks()` or `SteamAPI_ManualDispatch_RunFrame()` or `Steam_BGetCallback()`  
  hence all run_callbacks() will never run, also networking callbacks won't run

  ---

* **[breaking]** introduced a new config file `enable_experimental_overlay.txt`, which deprecates the config file `disable_overlay.txt`  
  in many occasions this feature was a source of crashes, so it's better to make it an opt-in option.  
  otherwise, the `experimental` and `Cold Client` builds of the emu will crash by default on startup for some apps/games 

  ---

* decrease the periodicity of the background thread to `~100ms`, also prevent it from running if the callbacks are already running
* output each function name in the debug log
* imitate Windows resources of gameoverlayrenderer + add resources to networkingsocketslib
* force add gameserver if `always_lan_type` was specified, not necessary but just in case
* allow injecting id string during build via command line switch `+build_str <str>`

---

## 2024/4/3 (hotfix 1)

* load achievements strings before creating fonts, so that their glyphs ranges are taken into consideration

---

## 2024/4/3

* **[detiam]** fix linking errors when building on archlinux
* **[detiam]** optimize Linux deps build script:
  - new argument `-packages_skip`: allows skipping installation of distro packages, such as `build-essential`, `gcc-multilib`, etc...
  - the above command introduced the ability to run without root
  - if the script was ran without root, and `-packages_skip` wasn't specified,  
    the script will attempt to detect and use the built-in tool `sudo` if it was available
* **[Detanup01]** Added Steamwork SDK version 159
* **[detiam]** added schinese and tchinese translations to the overlay
* **[detiam]** enhanced the overlay font
  - replace the builtin font with `Unifont`
  - allow loading a custom font whose location is defined in `overlay_appearance.txt`  
    fonts with relative paths will be loaded from `steam_settings\fonts`
* allow sharing leaderboards scores with connected players, adjust players ranks locally, and sort entries as needed by the game, suggested by **[M4RCK5]**  
  this will only work when people connected on the same network are playing the same game, once they disconnect their leaderboard entry will be lost (no data persistence for other players), also it doesn't work well with VPN clients.  
  this behavior could be enabled via `share_leaderboards_over_network.txt`
* implemented the missing interface `ISteamGameServerStats`, allowing game servers to exchange user stats & achievements with players  
  could be disabled via `disable_sharing_stats_with_gameserver.txt`,  
  you can also create `immediate_gameserver_stats.txt` to sync data immediately, but **not recommended**  
* for windows: updated stub drm patterns and added a workaround for older variants,  
  this increases the compatibility, but makes it easier to be detected
* for windows: new stub/mock dll `GameOverlayRenderer(64).dll` for the experimental cold client setup,  
  some apps verify the existence of this dll, either on disk, or inside their memory space.  
  **not recommended** to ignore it
* separated the config file `disable_leaderboards_create_unknown.txt`, previously it was tied to `leaderboards.txt`,  
  by default the emu will create any unknown leaderboards, you can disable this behavior with this file  
  **not recommended** to disable this behavior
* for the tool `generate_emu_config`:
  - don't generate `disable_xxx` config files by default
  - new option `-de`: generate config files inside `steam_settings` folder to disable some extra features of the emu  
    note that this option deprecates the option `-nd`
  - new option `-cve`: generate config files inside `steam_settings` folder to enable some convenient extra features of the emu  
  - allow specifying the username and password via the environment variables `GSE_CFG_USERNAME` and `GSE_CFG_PASSWORD`,  
  this will override the data specified in `my_login.txt`
* properly implement `Steam_User_Stats::ResetAllStats()`
* added missing example file `disable_lobby_creation.txt` in `steam_settings` folder + updated release `README`
* allow overlay invitations to obscure game input to be able to accept/reject the request
* fixed a problem in the overlay where players connected on the same network might be ignored during startup, resulting in an empty friend list
* set the minimum game server latency/ping to `2ms`
* added new function `rmCallbacks()` for the networking, to be able to cleanup callbacks on object destruction
* missing `delete` (cleanup) for `ugc_bridge` instance + reset pointers on client objects destruction
* for windows build script: prevent permissive language extensions via the compiler flag `/permissive-`

---

## 2024/3/17

* **[bitsynth]** Fix Age of Empires 2: Definitive Edition, the game expects the app itself to be an owned DLC,  
  otherwise most options will be disabled

* `Steam_Apps::GetCurrentBetaName()` make sure the out buffer is null terminated

---

## 2024/3/16

* manage overlay cursor input/clipping and internal frame processing in a better way,
  should prevent more games from pausing to display notifications
* initially attempt to load the icons of all achievements, this will slow things down at startup,  
  but avoids having to load the achievement icon during gameplay which causes micro-stutter
* avoid loading and resizing the achievement icon each time it's unlocked
* Local_Storage: avoid allocating buffers unless `stbi_load()` was successfull
* changed how manual callback dispatch is handled, now it won't run the background thread,  
  this might break stuff
* removed an outdated example file for dll injection in the `ColdClientLoader`
* refactor/restructure `steam_utils` into a separate cpp file

---

## 2024/3/9

* prevent notifications that do not require interaction from stealing focus 
* check for success when creating the overlay popup window
* make the backgrounds of notifications and popups less transparent (more visible), for easier visibility
* show hidden achievement description in the overlay if it was unlocked
* don't fail loading both achievement icons, locked and unlocked, if eihter one of them wasn't loaded but the other was

---

## 2024/3/8 (hotfix 1)

* don't allow posting overlay achievements notifications when the overlay isn't ready yet
* don't run overlay callback when it isn't ready yet
* don't initialize or setup the overlay when `disable_overlay.txt` is used

---

## 2024/3/8

* updated the ingame overlay project, suggested by **[CHESIRE721]**  
  Thanks to **[Nemirtingas]** for the amazing project: https://github.com/Nemirtingas/ingame_overlay
* for Linux: new experimental build of the emu with overlay support  
  currently only *some* 64-bit games using OpenGL will work
* use a new method to initialize the overlay on a separate thread with a configurable initialization delay and renderer detection timeout  
  - the new config file `overlay_hook_delay_sec.txt` controls the initial delay (default = `0 seconds`)  
  - the new config file `overlay_renderer_detector_timeout_sec.txt` controls the detection timeout (default = `15 seconds`)  

  check the updated `README`
* added builtin fonts to properly render all overlay translations:
  - `NotoSansJP-SemiBold`: for japanese
  - `NotoSansKR-SemiBold`: for korean
  - `NotoSansSC-SemiBold`: for simplified chinese
  - `NotoSansTC-SemiBold`: for traditional chinese
  - `NotoSansThai-SemiBold`: for Thai
  - `Google-Roboto-Medium`: for other languages
* added 2 new entries for the config file `overlay_appearance.txt`
  - `Font_Glyph_Extra_Spacing_x`: controls the extra horizontal spacing of characters (default = 1.0)  
  - `Font_Glyph_Extra_Spacing_y`: controls the extra vertical spacing of characters (default = 0.0)  
  
  the extra horizontal spacing is especially needed for non-latin characters, otherwise they are squeezed
* removed the source files of the ingame overlay project, it is now a dependency,  
  **rebuild your dependencies!**
* removed the code which locks the cursor inside the overlay window
* attempt to load the locked achievement icon from the json key `icongray` if the normal one failed, adding compatibility with older format
* cleanup/free overlay images on unhook
* free the detector instance once it's no longer needed
* use locks everywhere in the overlay + more debug messages
* fixed a bug in the settings parser where lines with 1 single character would be completely erased after trimming spaces
* fixed all compilation warnings produced by the overlay on Linux
* updated all build scripts

---

## 2024/2/29

* revert the changes to `steam_matchmaking_servers` and only enable them via the 2 new config files:
  - `matchmaking_server_list_actual_type.txt`: enable the behavior which allows steam matchmaking to use the actual type of the requestd server list, otherwise it's always LAN
  - `matchmaking_server_details_via_source_query.txt`: enable the behavior which allows steam matchmaking to use actual source server query to grab the server info

  thanks a lot to **[LuKeSt0rm]** for the help and testing

* added a new flag `-reldir` for the `generate_emu_config` script which allows it to generate temp files/folders, and expect input files, relative to the current workig directory, suggested by **[ImportTaste]**

---

## 2024/2/24

* build the python scripts `achievements_gen.py` and `parse_controller_vdf.py` into binary form using `pyinstaller` for a more user friendly usage, suggested by **[DogancanYr]**
* change the scripts `achievements_gen.py` and `parse_controller_vdf.py` to accept multiple files

---

## 2024/2/23

* more accurately handle and download steamhttp requests in multi-threaded manner:
  - hanlde `GET`, `HEAD`, `POST`
  - properly set `POST` data (raw and parameterized), and `GET` parameters
  - properly set request headers

* new config file `force_steamhttp_success.txt` in `steam_settings` folder, which forces the API `Steam_HTTP::SendHTTPRequest()` to always succeed

---
* **[breaking]** deprecated the config file `http_online.txt` in favor of the new one `download_steamhttp_requests.txt`

---

## 2024/2/20

* generate_emu_config: allow setting the steam id of apps/games owners from an external file `top_owners_ids.txt` beside the script, suggested by **[M4RCK5]**
* generate_emu_config: support the new format for `supported_languages`
* generate_emu_config: update the code which parses controller inputs
* generate_emu_config: always use the directory of the script for: the data `backup` folder, the `login_temp` folder, the `my_login.txt` file

---

## 2024/2/13

* cold client loader: validate the PE signature before attempting to detect arch

---

## 2024/2/10

* a hacky fix for the overlay on directx12, currently very slow when loading images
* limit the attempts to load the achievements images, to prevent a never ending FPS drop

---

## 2024/2/7

* new persistent modes for cold client loader, mode 2 is a more accurate simulation and allows launching apps from their .exe
* allow setting the IP country via the file `ip_country.txt`

---

* **[Breaking]** changed the ini sections of the cold client loader

---

## 2024/1/26

* **[Detanup01]** added a new command line option for the tool `generate_emu_config` to disable the generation of `disable_xxx.txt` files,  
  suggested by **[Vlxst]**
* added new settings to the overlay which allow specifying the notifications positions, check the example file `overlay_appearance.EXAMPLE.txt`,  
  suggested by **[ugurkahriman]**
* fixed a mistake when discarding the utf8 bom marker

---

## 2024/1/25

* added new options to the overlay to allow copying a friend's ID, plus current player ID, suggested by **[Vlxst]**
* added a new option to the overlay to invite all friends playing the same game, suggested by **[Vlxst]**
* added new `auto_accept_invite.txt` setting to automatically accept game/lobby invites from this list, each SteamID64 on a separate line  
  also you can leave the file empty to accept invitations from anyone, check the updated release readme, suggested by **[Vlxst]**
* added new `disable_overlay_warning_*.txt` settings to disable certain or all warnings in the overlay, suggested by **[Vlxst]**
  * `disable_overlay_warning_forced_setting.txt`:  
    - disable the warning for the usage of any file `force_*.txt` in the overlay
    - unlocks the settings menu, this may result in an undesirable output
  * `disable_overlay_warning_bad_appid.txt`: disable the warning for bad app ID (when app ID = 0) in the overlay
  * `disable_overlay_warning_local_save.txt`: disable the warning for using local save in the overlay

---

## 2024/1/20

* **[Detanup01]** added implementation for `Steam_Remote_Storage::EnumerateUserSubscribedFiles()` +   
  mods files handles in `Steam_Remote_Storage::UGCDownload()` + `Steam_Remote_Storage::UGCDownloadToLocation()`  
  which makes mods now work for many games
* **[Kola124]** enhanced the settings parser to detect primary and preview mod files sizes automatically +  
  use the base Steam URL by default for workshop URL + auto calculate the mod `score` from up/down votes  
  also thanks to **[BTFighter]** for providing logs
* **Breaking change** mod preview image file must exist in `steam_settings\mod_images\<MOD_ID>`
* an enhancement to the settings parser to attempt to auto detect mods when `mods.json` is not present, with the same behavior as when the json file was created.  
  this works for mods with only 1 primary file and only 1 preview file
* fixed the generated path of mod `preview_url`, previously it would contain back slashes `\` on Windows
* use last week epoch as the default time for mods dates (created, added, etc...)
* make sure the mod path is always normalized and absolute, required by some APIs
* `Steam UGC`: implement `SetUserItemVote()`, `GetUserItemVote()`, `AddItemToFavorites()`, `RemoveItemFromFavorites()`,  
  favorite mods list are now saved in `favorites.txt` in the user save data folder
* cold client loader can now inject user dlls, and force inject the `steamclient(64).dll` library,  
  also you can control the injection order via a file `load_order.txt`, check its readme and the provided example
* a new experimental dll (which must be injected first) to patch Stub drm v3.1 in memory, check the injection example of the cold client loader
* cold client loader will now treat relative paths as relative to its own path, previously it used the current active directory
* cold client loader no longer needs an explicit setting for the `ExeRunDir`, by default it would be the folder of the exe
* in cold client loader, the option `ResumeByDebugger` is now available for the release build
* cold client loader is now built for 32-bit and 64-bit separately, and will display a nag about architecture difference if for example the app was 32-bit and the loader was 64-bit, this could be disabled via the setting `IgnoreLoaderArchDifference=1`
* the cold client loader will output useful debug info when the debug build is used
* added a very basic crashes logger/printer, enabled by creating a file called `crash_printer_location.txt` inside the `steam_settings` folder, check README.realease.md for more details  
* fixed a problem in the overlay which would cause a crash for the guest player when an invitation was sent
* `Steam UGC`: make sure returned mod folder from `GetItemInstallInfo()` is null terminated, previously some apps would get a bad malformed string because of this
* `Steam_RemoteStorage`: very basic implementation for `GetQueryUGCNumTags()`, `GetQueryUGCTag()`, `GetQueryUGCTagDisplayName()`
* new function in local storage to get list of folders at root level, given some path
* imitate how the DOS Stub is manipulated during/after the build
* some fixes to the win build script + use the undocumented linker flag `/emittoolversioninfo:no` to prevent adding the MSVC Rich Header
* debug messages are now mostly scoped, ex: `Steam_Ugc::XXX`
* added a bunch of helper functions, `common_helpers::XXX` + `pe_helpers::XXX`

---

## 2024/1/5

* **[Detanup01]** Fixed parsing of old Steam interfaces, reported by **[LuKeStorm]**: https://cs.rin.ru/forum/viewtopic.php?p=2971639#p2971639  
* refactored the tool `find_intrfaces` to search accurately for old interfaces  

---

## 2024/1/3  

* added a new option to the Windows version of the client loader to aid in debugging.  
the option is called `ResumeByDebugger`, and setting it to `1` will prevent the loader from  
auto resuming the main app thread, giving you a chance to attach your debugger.  
* make the script `generate_emu_config` generate an empty `DLC.txt` if the app has no DLCs
* windows build: sign each file after build with a self-signed generated certificate + note in the release readme regarding false-positives
* windows build: note in readme about Windows SDK
* windows build: added vesion resource (.rc file)
* gen emu config: readme + icon attribution
* added anonymous login to gen emu script, these accounts have very limited access
* linux + win build scripts: introduce -verbose flag
* windows build script: ensure /MT when compiling
* output protoc generated in a subfolder in dll/ for easier code reference +  
  don't cleanup protoc generated files, because VScode gets confused and cannot find files/types

---

## 2023/12/21 - 2023/12/27

* **[Detanup01]** added option to send auth token with new Ticket! + an option to include the GC token  
  by default the emu will send the old token format for various APIs, like:  
  * `Steam_GameServer::GetAuthSessionTicket()`
  * `Steam_User::GetAuthSessionTicket()`
  * `Steam_User::GetAuthTicketForWebApi()`  

  this allows the emu to generate new ticket data, and additionally the GC token.  
  check the new config files `new_app_ticket.txt` and `gc_token.txt` in the `steam_settings` folder
* **[Detanup01]** fixed print issues in some places
* **[remelt]** use the `index` argument to grab the preview URL from UGC query result, fixed by: https://cs.rin.ru/forum/viewtopic.php?p=2964432#p2964432
* **[remelt]** allow overriding mod `path` & mod `preview_url` in the `mods.json` file, suggested by: https://cs.rin.ru/forum/viewtopic.php?p=2964432#p2964432
* allow setting the mod `score` in the `mods.json`
* when the mod `preview_url` is not overridden, don't set it automatically if `preview_filename` was empty, otherwise the `preview_url` will be pointing to the entire `mod_images` folder, like: `file://C:/my_game/steam_settings/mod_images/`  
  instead set it to an empty string
* updated `mods.EXAMPLE.json`
* added 2 new config files `is_beta_branch.txt` and `force_branch_name.txt`  
  by default the emu will report a `non-beta` branch with the name `public` when the game calls `Steam_Apps::GetCurrentBetaName()`  
  these new config files allow changing that behavior, check the `steam_settings` folder
* refactored the `steamclient_loader` script for Linux + new options and enhancements to make it similar to the Windows version, check its new README!
* for steamclient loader (Windows + Linux): pass loader arguments to the target exe, allowing it to be used from external callers, example by the `lobby_connect` tool
* deprecated the `find_interface` scripts, now the executable is built for Windows & Linux!
* included the `steam_settings.EXAMPLE` for Linux build
* updated release READMEs!
* added a README for the repo with detailed build steps
>>>>>>>>> ---

* check for invalid data pointer in `GetAuthSessionTicket()`
* additional sanity check in `InitiateGameConnection()` + print input data address in debug build
* moved the example `app id` and `interfaces` files inside `steam_settings` folder, to avoid encouraging putting files outside

>>>>>>>>> ---

* fixed all debug build warnings for Linux & Windows (no more scary messages!)
* updated Linux & Windows build scripts to avoid removing the entire build folder before building + introduced `clean` flag
* added licenses & sources of all extrnal libraries + added a new cryptography library `Mbed TLS`  
  you have to rebuilt the deps
* deprecated the separate/dedicated cleanup script for Windows, it's now inlined in the main build script
* For Windows build script: deprecated `low perf` & `win xp` options
* For Linux build script: deprecated `low perf` option
* restored all original but unused repo files into their separate folder
* lots of refactoring and relocation in the source repo:
  - all build stuff will be inside `build` folder
  - restructured the entire repo
  - generate proto source files in the `build\tmp` folder insead of the actual source folder

>>>>>>>>> ---

* `settings_parser.cpp`:
  - cleanup the settings parser code by split it into functions
  - increase the buffer size for `account_name` to 100 chars
  - increase the buffer size for `language` to 64 chars
* `common_includes.h`:
  - refactor includes order
  - added new helper function to keep yielding the thread for a given amount of time (currently unused)
* build scripts:
  - in Linux build scripts don't use `-d` flag with `rm`
  - added global build stat message
  - use an obnoxious name for the file handle variable used if the PRINT_DEBUG macro to avoid collisions, in the caller has a variable with same name
* don't cache deps build when pushing tag or opening pull requests
* remove hardcoded repo path + remove Git LFS flag since it's no longer needed

---

## 2023/12/20

* fixed the implementation of `BIsAppInstalled()`, it must lock the global mutex since it is thread-safe, otherwise it will cause starvation and the current thread wion't yield, which triggers some games

* more accurate behavior for `BIsAppInstalled()`, reject app ID if it was in the DLC list and isUnlockAllDlc was false

* basic implementation for `RequestAppProofOfPurchaseKey()` and `RequestAllProofOfPurchaseKeys()`

* a simple implementation for `GetEarliestPurchaseUnixTime()`

* more accurate implementation for `BGetSessionClientResolution()`, set both x & y to 0

* return false in `BIsDlcInstalled()` when the given app ID is the base game

* check for invalid app ID `uint32_max` in different places

* more accurate implementation for `BReleaseSteamPipe()`, return true if the pipe was released successfully

* lock the global mutex and the overlay mutex in different places just to be on the safe side, without it, some games suffer from thread starvation, might slow things down

* added missing env var `SteamOverlayGameId` to steam_client and client_loader

* added a startup timer + counter for reference, currently used to print timestamp in debug log

* consistent debug log location, for games that change cwd multiple times while running

* fixed error propagation in Windows build script, apparently set /a var+=another_var works only if another_var is a defined env var but NOT one of the "magic" builtins like errorlevel

---

## 2023/12/17
* More accurate implementation for BIsAppInstalled(), it now rejects uint32_max

* Allow behavior customizization via installed_app_ids.txt config file

* Limit/Lock list of installed apps on an empty file (similar to dlc.txt)

* Changed the behavior of GetCurrentBetaName() to comply with the docs, might break stuff

* Allow customizing the behavior via ne config files: `is_beta_branch.txt` + `force_branch_name.txt` 

* New script to generate native executable for `generate_emu_config` on Linux using pyinstaller

* Deprecate the old `RtlGenRandom()` in favor of the new `BCryptGenRandom()`

* Setup Github Worflows to:
  * Build `generate_emu_config` for `Linux` when you push code to a branch whose name matches the pattern `ci-build-gen-linux*`
  * Build `generate_emu_config` for `Windows` when you push code to a branch whose name matches the pattern `ci-build-gen-win*`
  * Build the emu for `Linux` when you push code to a branch whose name matches the pattern `ci-build-emu-linux*`
  * Build the emu for `Windows` when you push code to a branch whose name matches the pattern `ci-build-emu-win*`
  * Build everything when you push code to a branch whose name is `ci-build-all`
  * Build everything and create a release when you push a tag whose name matches the pattern `release*`

* Packaging scripts for both Windows & Linux, usable locally and via Github Workflows
  * For the emu:
    * First run `build_win_deps.bat` (Windows)  
    or `sudo ./build_linux_deps.sh` (Linux)
    * Run `build_win.bat release` + `build_win.bat debug` (Windows)  
    or `./build_linux.sh release` + `./build_linux.sh debug` (Linux)
    * Finally run `package_win.bat release` + `package_win.bat debug` (Windows)  
    or `sudo ./package_linux.sh release` + `sudo ./package_linux.sh debug` (Linux)
  * The same goes for `generate_emu_config` (scripts folder) but the scripts do not take any arguments, so no `release` or `debug`

* Added all third-party dependencies as local branches in this repo + refer to these branches as submodules, making the repo self contained

* use Unicode when sanitizing settings, mainly for local_save.txt config file
  + new dir "utfcpp": containg all the source/include files of this library: https://github.com/nemtrif/utfcpp
  + common_includes.h: include the new library "utfcpp"
  + settings.cpp: in Settings::sanitize(): convert to utf-32 first, do the sanitization, then convert back to std::string and return the result

* avoid locking the global mutex every time when getting the global steamclient instance
  + dll.cpp: in get_steam_client(): only lock when the instance is null and double check for null, should speed up things a little bit
* in different places, avoid locking gloal mutex if the relevant functionality was disabled
  + example in steam_user_stats.h: SetAchievement()
  + example in steam_overlay.cpp:
      + Steam_Overlay::AddMessageNotification()
      + Steam_Overlay::AddInviteNotification()

* explicitly use the ASCII version of Windows APIs to avoid conflict when building with define symbols UNICODE + _UNICODE
  - base.cpp: GetModuleHandleA()
  - steam_overlay.cpp: PlaySoundA()

* fix the implementation of RtlGenRandom stub:
  + return a number
  + use extern "C" if building in C++ mode

* add new build scripts for both Windows and Linux for a much easier dev/build experience,  
  both Windows and Linux scripts will run parallel build jobs for a much faster build times,  
  by default, the scripts will use 70% of the max available threads, but if the auto detection didn't work,  
  you can pass for example `-j 10` to the scripts to use 10 parallel jobs  
  
  on Linux, archives (.a files) of third party libraries are bundled wholly, and built statically via:  
  `-Wl,--whole-archive -Wl,-Bstatic -lssq -lcurl ... -Wl,-Bdynamic -Wl,--no-whole-archive`  
  this ensures that the final output binary (for example: libsteam.so) won't require these libraries at runtime

  + to build on Linux (I'm using latest Ubuntu on WSL)
    - run as `sudo ./build_linux_deps.sh`, this will do the following:
      + download and install the required build tools via `apt-install`
      + unpack the third party libraries (protobuf, zlib, etc...) from the folder `third-party` to `build-linux-deps`
      + build the unpacked libraries from `build-linux-deps`
      
      you only need this step once, additionally you can pass these arguments to the script:  
      + `-verbose`: force cmake to display extra info
      + `-j <n>`: force cmake to use `<n>` parallel build jobs
      
    - without sudo, run `./build_linux.sh` and pass the argument `release` or `debug` to build the emu in the corresponding mode, this will build the emu inside the folder `build-linux`  
      some additional arguments you can pass to the script:  
      + `-lib-32`: prevent building 32-bit libsteam_api.so
      + `-lib-64`: prevent building 64-bit libsteam_api.so
        
      + `-client-32`: prevent building 32-bit steamclient.so
      + `-client-64`: prevent building 64-bit steamclient.so
        
      + `-tool-clientldr`: prevent copying the script steamclient_loader.sh
      + `-tool-itf`: prevent copying the script find_interfaces.sh
      + `-tool-lobby-32`: prevent building executable lobby_connect_x32
      + `-tool-lobby-64`: prevent building executable lobby_connect_x64
        
      + `+lowperf`: (UNTESTED) pass some arguments to the compiler to prevent emmiting instructions for: SSE4, popcnt, AVX
        
      + `-j <n>`: force build operations to use `<n>` parallel jobs
    
  + to build on Windows (just install Visual Studio 2019/2022)
    - without admin, run `build_win_deps.bat`, this will do the following:
       + unpack the third party libraries (protobuf, zlib, etc...) from the folder `third-party` to `build-win-deps`
       + build the unpacked libraries from `build-win-deps`
      
      you only need this step once, additionally you can pass these arguments to the script:  
      + `-verbose`: force cmake to display extra info
      + `-j <n>`: force cmake to use `<n>` parallel build jobs
      
    - without admin, run `build_win.bat` and pass the argument `release` or `debug` to build the emu in the corresponding mode,  
      this will build the emu inside the folder `build-win`
      some additional arguments you can pass to the script:
      + `-lib-32`: prevent building 32-bit steam_api.dll
      + `-lib-64`: prevent building 64-bit steam_api64.dll
        
      + `-ex-lib-32`: prevent building `experimental steam_api.dll`
      + `-ex-lib-64`: prevent building `experimental steam_api64.dll`
        
      + `-ex-client-32`: prevent building `experimental steamclient.dll`
      + `-ex-client-64`: prevent building `experimental steamclient64.dll`
        
      + `-exclient-32`: prevent building experimental `client steamclient.dll`
      + `-exclient-64`: prevent building experimental `client steamclient64.dll`
      + `-exclient-ldr`: prevent building experimental `client loader steamclient_loader.exe`
        
      + `-tool-itf`: prevent building executable `find_interfaces.exe`
      + `-tool-lobby`: prevent building executable `lobby_connect.exe`
        
      + `+lowperf`: (UNTESTED) for 32-bit build only, pass the argument `/arch:IA32` to the compiler
        
      + `-j <n>`: force build operations to use `<n>` parallel jobs

* added all required third-party libraries inside the folder `third-party`

* greatly enhanced the functionality of the `generate_emu_config` script + add a build script
  + run `recreate_venv.bat` to
     + create a python virtual environemnt
     + install all required packages inside this env
  + run `rebuild.bat` to produce a bootstrapped .exe built using `pyinstaller`
  + inside the folder of the built executable
     + create a file called `my_login.txt`, then add your username in the first line, and your password in the second line
     + run the .exe file without any args to display all available options
    

* revert the changes to `SetProduct()` and `SetGameDescription()`

* in `steam_overlay.cpp`, in `AddAchievementNotification()`: prefer original paths of achievements icons first, then fallback to `achievement_images/`

---

## Older changes
* add missing implementation of (de)sanitize_string when `NO_DISK_WRITE` is defined which fixes compilation of `lobby_connect`

* check for empty string in (de)sanitize_file_name() before accessing its items
