Changelog:

Upscaling and downscaling options in the graphics settings now work correctly on Vulkan. Previously, the hermite and bicubic scaling options would only work on OpenGL and silently fall back to bilinear filtering on Vulkan
Graphic pack support for custom scaling shaders has been reworked and is now functional on Vulkan, with fixes carrying over to OpenGL. If you are a graphic pack developer see #1392 for details
Cemu will now show an error if the MLC directory is not writeable
Added a workaround for graphic driver crashes seen in the eShop versions of Fatal Frame. These are caused by the game shipping with shaders that contain infinite loops. The actual hardware has an escape mechanism for this that we don't yet emulate
Added support for connecting Wiimotes via L2CAP on Linux (Details in #1353)
Set correct version for MacOS bundle
Updated Arabic, German, Russian and Swedish translations

This is the major release of Cemu 2.1 with a cumulative changelog which includes the changes from all 93 experimental releases since Cemu 2.0.
For users that were already using our experimental updates (2.0-x), you can think of this release as the final experimental update. There are no noteworthy additional changes compared to Cemu 2.0-95 other than the new version number.

Starting with this release, Cemu will now only have a single release channel. Instead of experimental releases, there is a new option to control whether Cemu will update immediately to cutting-edge releases, which may contain uncaught bugs, or update with a slight delay. More details on this can be found here

Changelog

Major new additions:

Added appimage and flatpak releases for Linux
Added an experimental release for macOS. Available for x86-64 only for now but it can be run on ARM macs through Rosetta 2 emulation. MoltenVK is used as the graphics backend
Added a tool to emulate the USB portals for Skylanders and Disney Infinity

Many changes to improve robustness of the Linux build
Added debug option to create core dumps on crash
Improved diagnostics logging in case of crashes or other exceptions. Cemu is now also shipped with symbols so that stack traces show function names
The CPU and memory statistics in the overlay now work on Linux
The background colors of the Game List now match the brightness of the window theme instead of always using bright colors
Fixed an issue where closing the GamePad window would freeze Cemu
Fixed a bug where the GamePad window would not render anything with OpenGL
Fixed an issue where some UI dialogs would cause Cemu to crash after closing them
Fixed many smaller UI issues specific to WxWidget's wxGTK backend

UI:

Added Receive untested updates option to general settings. More info here
Added Open Cemu folder and Open MLC folder options to the File menu
Added new options when right-clicking a game inside the Game List
- Copy the title ID, name or icon of a game
- Delete the shader cache of a game

Fixed empty title names in Title Manager if the console language is set to something other than English
Fixed an issue where custom game names would not show in the Game List when it was set to icon mode
Fixed an issue where an extra "c" entry would show up in the save import/export dropdown in the Title Manager
Fixed an incorrect error message that could occur while installing games due to a mistake in the calculation of free disk space
The font size of overlay text will now scale according to the display's DPI
Fixed a crash that would occur when clicking on the Format column header in the Title Manager
Use the long title names in the Game List instead of the short name. This was changed due to some games which have cut-off short names
UI elements for options that cannot be changed at runtime are now grayed out when a game is running
Simplified the Getting Started dialog
Various smaller tweaks and restructuring of the UI to make Cemu more user-friendly

CPU:

Improved emulation of PowerPC overflow condition. Improves compatibility with some Unity and DS Virtual Console games

GPU core (Latte):

Added support for more shader instructions, some of which are necessary for homebrew shaders compiled with CafeGLSL
Optimized output of the shader decompiler which slightly reduces shader compilation times
Removed shaderMulAccuracy min option since it has no measurable benefits over the other options
Use better hashing for the buffer cache to avoid hash collisions. Fixes a bug in BotW where the weapon trail effect would sometimes render in a solid red color for a single frame
Added support for a missing vertex format used by Rabbids Land
Corrected calculation of FragCoord.w. Fixes rendering issues in DS Virtual Console games
Fixed several issues where the shader decompiler could generate broken GLSL. Fixes rainbow colors on characters in Tekken Tag Tournament 2
Various smaller optimizations

OpenGL:

Removed -legacy command line parameter which has been non-functional for a long time. Originally this would disable some features to fix crashes on pre-2015 Intel GPU drivers
Cemu should no longer crash if OpenGL fails to initialize
Fixed a regression where Cemu's precompiled shader cache for OpenGL wasn't actually used
Lowered latency of texture readback. This fixes severe FPS drops in BotW whenever something is lit on fire

Vulkan:

The option Async shader compile is now enabled by default
Multi-threaded pipeline compilation during the shader cache loading screen is now again enabled on Nvidia drivers which results in much faster pipeline loading
Fixed incorrect decoding of R4G4 texture format when VK_FORMAT_R4G4_UNORM_PACK8 is not supported. Fixes invisible rupee counter in Twilight Princess HD
Several changes to make Cemu align more with the Vulkan specification
Avoid a crash if validation layer is enabled but not installed
Improve floating point emulation accuracy in shaders when VK_KHR_SHADER_FLOAT_CONTROLS extension is available. This fixes mobs in Minecraft having misplaced limbs
Added support for R32_X8_FLOAT color texture format
Allow RGBA16F texture format with SRGB bit. Fixes a crash in Sonic Transformed
Fixed stencil front mask using the value of the back mask
Enhanced synchronization of draw calls involving textures that are read from and written to simultaneously. Resolves an issue with broken heightmaps in BotW on the Mesa RADV driver
Resolved a crash that occurred when the pipeline cache failed to open due to corruption or other issues

Online Functionality:

Fixed online connectivity for accounts in North America region after Wii U system update 5.5.6
Added option to switch between Nintendo, Pretendo or custom server URLs
Online mode and server selection can be set per-account instead of only globally
The Download Manager will always connect to Nintendo servers even if the current account is set to Pretendo or custom servers. This avoids the hassle of having to switch server settings temporarily to use the Download Manager
Fixed SpotPass downloads not working at all on Linux/MacOS and generally improved robustness of SpotPass downloads
Correctly set the current app in the friend status so it doesn't show up as "???" to other friends anymore
