 Revision history for SPIRV-Tools
 
-v2018.2-dev 2018-03-02
- - Start v2018.2 development
+v2018.2-dev 2018-03-07
+ - General:
+ - Support SPIR-V 1.3 and Vulkan 1.1.
+   - Default target environment is now SPIR-V 1.3.  For command-line tools,
+     use the --target-env option to override the default.  Examples:
+        # Generate a SPIR-V 1.0 binary instead of SPIR-V 1.3
+        spirv-as --target-env spv1.0 a.spvasm -o a.spv
+        spirv-as --target-env vulkan1.0 a.spvasm -o a.spv
+        # Validate as Vulkan 1.0
+        spirv-val --target-env vulkan1.0 a.spv
+   - Support SPV_GOOGLE_decorate_string and SPV_GOOGLE_hlsl_functionality1
+ - Fixes:
+   - Fix Android.mk build. Compilation was failing due to missing definitions of
+     SpvCapabilityFloat16ImageAMD and other enumerated values.
+   - Optimizer: Avoid generating duplicate names when merging types.
+   - #1375: Validator: SPV_AMD_gpu_shaer_half_float implicitly allows declaration
+     of the 16-bit floating point type.
+   - #1376: Optimizer: Avoid folding half-precision float.
