v1.2.73 (#231)

Significant changes include LDN functionality from @Vudjun (no more
separate build!) and an XCI trimmer from @amurgshere.

Merged PRs in this release (in the order they were merged): 
#183, #150, #105, #160, #188, #98, #158, #13, #216, #73, #217, #122,
#228, #65, #226, #236, #247, #243, #249, #242, #260, #273, #272, #262,
#259, #241

## Versioning:
There now exists "stable" (release branch) and ["canary" (master
branch)](https://github.com/GreemDev/Ryujinx-Canary/releases) versions.
Instead of everyone using the same emulator, getting updates for every
code change, you now *opt-in* to the more frequent updates by using the
Canary version. Use stable and you'll get about an update a week, but
that update will be MUCH more significant as it's the entire previous
week's changes & PR merges.

## LDN
LDN functionality is now merged! Use
[this](https://github.com/GreemDev/Ryujinx/wiki/Multiplayer%E2%80%90(LDN%E2%80%90Local%E2%80%90Wireless)%E2%80%90Guide)
to get started.
Please note that LDN is only for local wireless; **this is not a
Nintendo Switch Online emulation feature**.

## UI
  - Added an XCI trimmer (#105).
- You can use this feature to trim dead bytes & the embedded firmware
out of your dumped XCIs, to make them smaller.
- If you right-click an XCI and the trim button it is greyed out, that
means your XCI is already as small as possible.
  - Fix for fullscreen not being really fullscreen (#150)
  - Fix window sizing calculations when Show Title Bar is enabled (#247)
- The "Install/Uninstall file types" buttons will be enabled/disabled
depending on which one you contextually need; install will be clickable
when they aren't installed, and vice versa.
- Fix for showing default config screen when swapping players in
controller settings (#122)
- Command-line argument to prevent update checking `--hide-updates`
(#272)
  - # RPC: 
    - Added a LOT of game images to Discord RPC.
    - Play time will now show the time unit hours at a maximum.

## Localization
- Update outdated/incorrect & added missing translations for zh-TW
(#158)
  - Add many missing locale strings to all languages (#160)
  - Update & improve Korean translation (#226)
  - Minor fixes & add missing translations to Spanish translation (#242)

## Headless
- Added `ignore-controller-applet` as an option you can configure via
headless command-line options.

## Graphics Backend
  - ### Vulkan
    - fix divide-by-zero when recovering from missed draw (#235) 
      - fixes crash in 'Baldo: The Guardian Owls' opening cutscene
    
## Horizon
- fix crash that occurs when launching an NSP forwarder generated by
Nro2Nsp (#237)

# Nerd Zone
Slightly more technical information. If you don't understand what's
under here, no worry.

- Updater now uses the release's Tag Name instead of its Name for
version checking.
- Baked in value change logging into ReactiveObject.
- Split ConfigurationState into 3, smaller partial classes of the same
name.
- Specify if the current version is Canary in the version log line

+## Compilation
+
+Building the project is for users that want to contribute code only.
+If you wish to build the emulator yourself, follow these steps:
+
+### Step 1
+
+Install the [.NET 8.0 (or higher) SDK](https://dotnet.microsoft.com/download/dotnet/8.0).
+Make sure your SDK version is higher or equal to the required version specified in [global.json](global.json).
+
+### Step 2
+
+Either use `git clone https://github.com/GreemDev/Ryujinx` on the command line to clone the repository or use Code --> Download zip button to get the files.
+
+### Step 3
+
+To build Ryujinx, open a command prompt inside the project directory.
+You can quickly access it on Windows by holding shift in File Explorer, then right clicking and selecting `Open command window here`.
+Then type the following command: `dotnet build -c Release -o build`
+the built files will be found in the newly created build directory.
+
+Ryujinx system files are stored in the `Ryujinx` folder.
+This folder is located in the user folder, which can be accessed by clicking `Open Ryujinx Folder` under the File menu in the GUI.

-## Compatibility
-
-As of May 2024, Ryujinx has been tested on approximately 4,300 titles;
-over 4,100 boot past menus and into gameplay, with roughly 3,550 of those being considered playable.
-
-Anyone is free to submit a new game test or update an existing game test entry;
-simply follow the new issue template and testing guidelines, or post as a reply to the applicable game issue.
-Use the search function to see if a game has been tested already!
-
 ## Usage
 
 To run this emulator, your PC must be equipped with at least 8GiB of RAM;
 failing to meet this requirement may result in a poor gameplay experience or unexpected crashes.
 
-## Latest release

-Releases are compiled automatically for each commit on the master branch.
+Stable builds are made every so often onto a separate "release" branch that then gets put into the releases you know and love. 
-While we strive to ensure optimal stability and performance prior to pushing an update, our automated builds **may be unstable or completely broken**.
+These stable builds exist so that the end user can get a more **enjoyable and stable experience**.

-Building the project is for advanced users.
-If you wish to build the emulator yourself, follow these steps:
-
-### Step 1
-
-Install the [.NET 8.0 (or higher) SDK](https://dotnet.microsoft.com/download/dotnet/8.0).
-Make sure your SDK version is higher or equal to the required version specified in [global.json](global.json). 
-
-### Step 2
-
-Either use `git clone https://github.com/GreemDev/Ryujinx` on the command line to clone the repository or use Code --> Download zip button to get the files.
-
-### Step 3
-
-To build Ryujinx, open a command prompt inside the project directory.
-You can quickly access it on Windows by holding shift in File Explorer, then right clicking and selecting `Open command window here`.
-Then type the following command: `dotnet build -c Release -o build`
-the built files will be found in the newly created build directory.
-
-Ryujinx system files are stored in the `Ryujinx` folder.
-This folder is located in the user folder, which can be accessed by clicking `Open Ryujinx Folder` under the File menu in the GUI.

 ## Quick Code Review Rules

+* All changes should follow the existing code style. You can read more about our code style at [docs/coding-style](../coding-guidelines/coding-style.md).
 * Adding external dependencies is to be avoided unless not doing so would introduce _significant_ complexity. Any dependency addition should be justified and discussed before merge.
 * Use Draft pull requests for changes you are still working on but want early CI loop feedback. When you think your changes are ready for review, [change the status](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/changing-the-stage-of-a-pull-request) of your pull request.
 * Rebase your changes when required or directly requested. Changes should always be commited on top of the upstream branch, not the other way around.
