## Summary
xemu's pre-release build caf7f22 brings Vulkan 1.4 support to the nv2a graphics backend alongside dynamic SPIR-V target selection. The release fixes 17 issues including memory leaks, missing texture formats, and incorrect lighting calculations. Eight commercial Xbox titles see resolved graphical problems, from fire effect artifacts in Splinter Cell: Pandora Tomorrow to water surface rendering in Prince of Persia: The Sands of Time.

## What's new in xemu's Vulkan backend
- **Vulkan 1.4 upgrade**: nv2a/vk backend now supports Vulkan 1.4, with SPIR-V compilation targeting the version the device supports at runtime
- **Memory leak fix**: Resolves null render memory leak in slow VGA path (issue #2906)
- **Texture format additions**: Y16 texture formats now implemented; clear handling enabled for X1A7 surface formats
- **Lighting and shader fixes**: Spotlight falloff, specular parameters, and texgen view model (infinite viewer) now implemented; point sprites correctly restricted to point rendering
- **macOS stability**: Fixed epoxy debug function flakiness on macOS
- **CI improvements**: xemu-test now runs on pull requests; AppImage uses host GLib

## Why it matters
The Vulkan 1.4 upgrade and SPIR-V improvements position xemu to better leverage modern GPU capabilities across platforms. Fixes for high-profile titles like Splinter Cell: Pandora Tomorrow and MechAssault 2 improve xemu's viability for preservation of the original Xbox library.
