You’re encouraged to review the comprehensive changelog.
Universal
New 1st anniversary icon
Firmware 22.0 compatibility
Eliminated the separate logging thread
Now, all logging occurs in situ
Stubbed GetFriendListForViewerV2
Qlaunch no longer crashes when viewing friends
Various changes to streamline the final assembly of the binary (host executable) to enhance cleanliness and reduce indirection
This includes new C++ guidelines for code structuring and improved compilation
These changes do not affect JIT-generated code (i.e., the code of the programs running under the emulator), only the emulator itself
Resolved Qlauncher crashing when opened multiple times
Introduced built-in auto-updater
Common global random number generator
Fixed crashes related to shared_memory
Resolutions for Tomodachi Life (boot)
Updated firmware constants to 22.0 and Atmosphere to 1.10.2
Improved TLS fetching performance on thread_data
Renderer
Global Vulkan maintenance fixes and improvements across all platforms
Notable fixes for performance and accuracy
Streamlined texture cache GC
Corrected index scaling for descriptors
Marked sampled image descriptor indices as non-uniform
Managed dynamic texture descriptor strides
Enabled GPU-async for additional platforms
SPIRV-Opt has been removed
This means no more SPIRV optimizations
…many of which were ineffective and only made shader compilation significantly slower
Enhanced Lanczos filtering shader
Unrolling loops results in a slight performance boost
Fixed CBuf get/set for composite types
Set high Z-index to correct keyboard display
Primarily impacts TL:LTD
Resolved Maxwell3D processing consistently marking dirty flags
Vertex buffer now uses static storage
Desktop
MSVC builds have been replaced with clang-cl
This change arises from GitHub runners upgrading MSVC 2022 to MSVC 2026, which introduced compiler bugs
Corrected mod manager bugs
Lifted fastmem ban for FreeBSD
The issue was with vm_reclaim_contig in the kernel when using incorrect flags, fixed on 15
Resolved FFmpeg not recognizing VA-API on FreeBSD
Android
Enhanced compatibility and performance for QCOM and Snapdragon
Introduced an option to manage the number of Vulkan workers on Android (from 4 to 8)
Enabled legacy rescale pass on Android
This resolves issues for games like LM3
Dynarmic
Several enhancements to the dispatcher, decoder, and IR constructor
Improves JIT latency
Removed unnecessary ARM decode matcher indirection
Implemented VectorMin/Max{S,U}64 emitters
Allows Sonic Crossworlds, and several other games, to boot on macOS and WoA
Proper MWAIT push/pop handling
Addresses specific CPUs with such instructions
Prevents crashes
Improved GDB features
Removed VTable bounce hack
While this was essential for PKZA, it is no longer required
mcl dependency has been eliminated
Internal
Facilitated FFmpeg cross compilation
This should significantly ease porting efforts (OpenSSL pending)
Expanded documentation on debugging and compilation
Resolutions for issues using XCode CMake generator
Fixes for RISC-V builds
Though not yet production-ready, it now compiles.
Removed shader directory regeneration
This disrupts compatibility with *BSD make but ensures proper shader file regeneration
Addressed liquid glass icon issue on macOS
