0.11.2 (2022-11-03)

Features:

  • Added the new WasmEdge C API.
    • Added the WasmEdge_ConfigureSetForceInterpreter() API to set the force interpreter mode.
    • Added the WasmEdge_ConfigureIsForceInterpreter() API to check the force interpreter mode in configurations.
    • Added the WasmEdge_LogOff() API to turn off the logging.
    • Due to introducing the new APIs, bump the SOVERSION to 0.0.1.
  • Added the additional hint messages if import not found when in instantiation.
  • Added the forcibly interpreter execution mode in WasmEdge CLI.
    • Users can use the --force-interpreter option in the wasmedge tool to forcibly execute WASM files (includes the AOT compiled WASM files) in interpreter mode.
  • Supported WASI-NN plug-in with TensorFlow-Lite backend on Ubuntu 20.04 x86_64.
    • Users can refer to the WASI-NN document for the information.
    • For building with enabling WASI-NN with TensorFlow-Lite backend, please add the -DWASMEDGE_PLUGIN_WASI_NN_BACKEND="TensorFlowLite" in cmake.
  • Bump the fmt format of logging to 9.0.0.
  • Added the new experimental edge-triggered epoll API epollOneoff in the WASI component.

Fixed issues:

  • Detected the valid _start function of the WasmEdge CLI command mode.
    • For the invalid _start function, the WasmEdge CLI will execute that function in the reactor mode.
  • Fixed the non-English WasmEdge CLI arguments error on Windows.
  • Fixed the AOT compiler issues.
    • Fixed the operand of frintn on arm64 platforms.
    • Corrected the unreachable status to record on every control stacks.
  • Refined the Loader performance.
    • Capped the maximum local counts to 67108864 (2^26).
    • Rejected wrong data when loading the universal WASM.
    • Rejected the unreasonable long vector sizes.
  • Fixed the lost std namespace in the experimental::expected.
  • Fixed the repeatedly compilation of universal WASM format.
    • If users use the wasmedgec tool to compile the universal WASM file, the AOT compiled WASM data will be appended into the output.
    • In the cases of duplicated AOT compiled universal WASM file which has more than 1 section of AOT compiled WASM data, the WasmEdge runtime will use the latest appended one when execution.
  • Hided the local symbols of the WasmEdge shared library.
  • Loaded the default plug-in path from the path related to the WasmEdge shared library.
    • This only fixed on the MacOS and Linux platforms now.
  • Updated the minimum CMake required version on Android.

Known issues:

  • Universal WASM format failed on MacOS platforms.
    • In current status, the universal WASM format output of the AOT compiler with the O1 or upper optimizations on MacOS platforms will cause bus error when execution.
    • We are trying to fix this issue. For working around, please use the --optimize=0 to set the compiler optimization level to O0 in wasmedgec CLI.
  • WasmEdge CLI failed on Windows 10 issue.
  • Plug-in linking on MacOS platforms.
    • The plug-in on MacOS platforms will cause symbol not found when dynamic linking.
    • We are trying to fix this issue. For working around, please implement the host modules instead of plug-ins.

Documentations:

Tests:

  • Added the WASI-NN TensorFlow-Lite backend unit test.
  • Added the new C API unit tests.
  • Applied more fuzz tests for WasmEdge CLI.
