- Fixed 64-bit pointer truncation in CUtlMemoryAligned affecting shadows and meshes. - Resolved heap corruption in GameUI and GamepadUI music systems (mismatched new[]/delete). - Fixed out-of-bounds touch input crashes by mapping 64-bit SDL finger IDs. - Lowered OpenGL requirement to 3.0 on Android and added fallbacks for GLES 3.2+ functions. - Fixed GamepadUI text wrapping and lifecycle crashes.
