Mar 1, 2025March 2025: Intel/gits OpenGL subcapture stability improvements. Fixed crashes caused by missing/unknown uniform types, expanded the UniformDimensions mapping, added robust error logging and exception handling, and completed a focused refactor to improve type management and readability. Also addressed multisample uniform types to prevent related issues. These changes reduce null-value crashes, improve runtime resilience, and shorten time-to-diagnose for future regressions.

Feb 1, 2025February 2025 monthly summary for intel/gits focusing on key deliverables and impact. Highlights include a critical interoperability fix for GL framebuffer object extension mixing (GL_ARB_framebuffer_object and GL_EXT_framebuffer_object) with a user-facing warning and a robust workaround to improve cross-extension compatibility. Implemented a fallback by searching EXT maps when non-EXT maps fail, reducing rendering failures in mixed-extension applications and enhancing stability across drivers. Key outcomes: - Stabilized rendering for apps that mix FBO extensions; reduced unmapping-related issues and support questions. - Clean, maintainable fix with a targeted commit stream (83b83baca3fe2382c84f99004440962f58d7b554).

Nov 1, 2024November 2024 highlights: Vulkan code generation modernization for intel/gits, with the new Vulkan Generator Core enabling improved scaffolding, deduplication, data correctness, output ordering, IDs support, and type categorization via generate_vk.py and related fixes. A comprehensive Makoto/Mako templating layer was introduced to cover Vulkan wrappers, IDs, logging, drivers, and wrappers, including templates for def files and multiple auto-generated artifacts. The tooling now includes an expanded set of templates for code generation targets (functions, pre/post auto, headers, tracer, enums, arguments, and struct storage). Quality and stability improvements were delivered through without_older_versions, deduplicated Original()/Value() code paths, Python <3.11 IntFlag fixes, and a code-gen build bug fix. Migration to the new generator is complete: the new generator is default, the old one has been removed, and license headers were added to the Vulkan layer JSON.
