 # WasmSDK
-## Version : 1.1.0
+## Version : 1.1.1
 
 WasmSDK is a toolchain for WebAssembly (WASM).  In addition to being a general purpose WebAssembly toolchain, [EOSIO](https://github.com/eosio/eos) specific optimizations are available to support building EOSIO smart contracts.  This new toolchain is built around [Clang 7](https://github.com/eosio/llvm), which means that the SDK has the most currently available optimizations and analyses from LLVM, but as the WASM target is still considered experimental, some optimizations are not available or incomplete.
