2125.0 Alpha 4 is an amendment to Alpha 3 which addresses an issue which caused the Android build to crash when launched (#1810). It is otherwise identical to Alpha 3.
As 2125.0 Alpha 3 has been removed due the the issue, Alpha 3's changelog has been copied below ver-batim:
Azahar 2125.0-alpha3 Changelog
libretro
Azahar is now available as libretro/RetroArch cores for various OS platforms. | @warmenhoven #1215 + other PRs
Below is a list of platforms with available cores in this initial release:
Linux (x86_64)
Windows (x86_64)
macOS (arm64)
macOS (x86_64)
Android (arm64)
iOS
tvOS
Other platforms and architectures may be added in subsequent releases.
It's important to note that, due to restrictions around the use of JIT compilation on the App Store, the iOS and tvOS have JIT forcefully disabled by default* on those platforms. Disabling JIT has a big impact on performance, so emulation speed may be below 100% on devices other than those which have been released relatively recently.
* For more information, read here: https://docs.libretro.com/guides/install-ios/#jit
When 2125.0 is fully released, the Azahar core will be available via the RetroArch core downloader and as a built-in core on iOS and tvOS.
All
Greatly reduced CPU usage of Azahar while using Artic Base. | @keynote #1789
Shader and pipeline compilation tasks are now handled by separate workers, improving parallelism and slightly reducing shader compilation stutter. | @PabloMK7 #1802
Fixed an issue with the previously introduced Vulkan shader disk cache where transferring the cache between devices could cause graphical issues. | @PabloMK7 #1770
Fixed unnecessary file IO spam while reading from Vulkan shader disk cache. | @PabloMK7 #1774
Very minor optimization for log message filtering, effective when a large number of LOG_DEBUG messages are produced in a short time-frame. | @PabloMK7 #1773
Added HLE implementation for Download Play (DLP) client. | @lannoene #1741
The DLP LLE module is no longer required to connect to Download Play sessions.
The LLE module is still required in order to host Download Play sessions.
Implemented new "Integer Scaling" option. @DavidRGriswold #1400
Added a new "Layouts to Cycle" setting, which allows users to select which layouts are cycled by the Cycle Layout/Toggle Layout hotkey. | @DavidRGriswold #1430
Apply the selected texture filter to color surfaces, not just texture surfaces. | @PabloMK7 #1784
Major refactor of configuration backend for all platforms, improving maintainability | @OpenSauce04 #1762
This change is primarily a developer-facing one, but does somewhat affect end-users on Android by having the default config.ini file be dynamically generated and validated, meaning that keys which were missing in the default config file are now present. | @OpenSauce04 #1762
Android
Added a new "Hotkey Enable" button bind. This button can be used in button combinations to activate hotkeys. | #1464
See the linked PR for a more detailed explanation.
Added new "Auto-Map Controller" button which functions similarly to its desktop equivalent. | @RJNY #1769
The drawer menu now always uses the layout appropriate for the current device orientation. | @DavidRGriswold #1473
macOS
Fixed a possible UI freeze during game list population. | @TeamPuzel #1785
Windows
Explicitly tell AMD drivers to use the dedicated GPU by default if an integrated GPU is available. | @RedBlackAka #1783
