16.6.0 2026-09-10

New Extensions

• Implement GL_EXT_cooperative_matrix_maintenance1
• Implement GL_EXT_optional_input_attachment_index
• Implement DebugEntryPoint for NonSemantic.Shader.DebugInfo 102

SPV_KHR_abort / abortEXT

• Require the first parameter of abortEXT to be a string literal, emit an error if it is not
• Require the first parameter of printf to be a string literal, emit an error if it is not
• Fix abort message struct layout for matrix, vector, and aggregate arguments
• Pack the abort message with scalar layout when the shader requests GL_EXT_scalar_block_layout
• Pack the abort message with scalar layout unconditionally so that consumers use one fixed set of rules
• Fix abort message type to use separate value and laid out types, removing invalid ArrayStride on constant types
• Fix abort to handle boolean and opaque types correctly

API Changes

• Add access to the source entry point in the C API

Bug Fixes

• Fix relaxed Vulkan access chain traversal for buffer references
• Fix 32-bit identity fillers used in 16-bit matrix constructors
• Fix out-of-bounds slot access for atomic_uint in reserveResourceSlot
• Fix out-of-bounds read when folding component-wise intrinsics on matrices
• Fix out-of-bounds dereference on undeclared ray tracing location
• Fix out-of-bounds read on empty entryPoints in postProcessFeatures
• Fix out-of-bounds read on short coopMatPerElementNV argument list
• Fix crash on empty struct initializers in cascading error mode
• Guard empty block member list in getBlockSize
• Validate argument count in decomposeStructBufferMethods
• Require constant scope and semantics operands in memorySemanticsCheck
• Fix string escaping in preprocessed output
• Fix Aligned decoration on buffer_reference swizzle-store read-modify-write load
• Fold bit-cast conversions as constant expressions
• Fold hyperbolic functions (sinh, cosh, tanh, asinh, acosh, atanh) as constant expressions
• Improve parsing of #pragma STDGL

Performance

• Replace linear search with a hash table for composite and struct constant creation in the SPIR-V builder
