      • Please refer to the documentation for how to upgrade.
      • Removed the WasmEdge_HostRegistration_WasiNN enum and the WasmEdge_ModuleInstanceCreateWasiNN() API.
      • Removed the WasmEdge_HostRegistration_WasiCrypto_Common enum and the WasmEdge_ModuleInstanceCreateWasiCryptoCommon() API.
      • Removed the WasmEdge_HostRegistration_WasiCrypto_AsymmetricCommon enum and the WasmEdge_ModuleInstanceCreateWasiCryptoAsymmetricCommon() API.
      • Removed the WasmEdge_HostRegistration_WasiCrypto_Kx enum and the WasmEdge_ModuleInstanceCreateWasiCryptoKx() API.
      • Removed the WasmEdge_HostRegistration_WasiCrypto_Signatures enum and the WasmEdge_ModuleInstanceCreateWasiCryptoSignatures() API.
      • Removed the WasmEdge_HostRegistration_WasiCrypto_Symmetric enum and the WasmEdge_ModuleInstanceCreateWasiCryptoSymmetric() API.
      • Removed the WasmEdge_HostRegistration_WasmEdge_Process enum and the WasmEdge_ModuleInstanceCreateWasmEdgeProcess() API.
  • Changed the WasmEdge_VMCleanup() behavior.
    • After calling this API, the registered modules except the WASI and plug-ins will all be cleaned.
  • Standaloned the WasmEdge-Process plug-in.

    • Added the WasmEdge_PluginLoadFromPath() API for loading a plug-in from a specific path.
    • Added the WasmEdge_PluginListPluginsLength() and WasmEdge_PluginListPlugins() APIs for getting the loaded plug-in names.
    • Added the WasmEdge_PluginFind() API for retrieving a loaded plug-in by its name.
    • Added the WasmEdge_PluginGetPluginName() API for retrieving the plug-in name.
    • Added the WasmEdge_PluginListModuleLength() and WasmEdge_PluginListModule() APIs for listing the module names of a plug-in.
    • Added the WasmEdge_PluginCreateModule() API for creating the specific module instance in a plug-in by its name.
  • Added the VM APIs.
    • Added the WasmEdge_VMGetRegisteredModule() API for retrieving a registered module by its name.
    • Added the WasmEdge_VMListRegisteredModuleLength() and WasmEdge_VMListRegisteredModule() APIs for listing the registered module names.
  • Introduced the python version WasmEdge installer.
  • Updated the ABI of the wasi_ephemeral_sock.
    • Added the output port of the sock_recv_from.
    • Updated the API of sock_getlocaladdr.
    • Unified the socket address size to 128-bit.
  • Supported using libtool to archive the WasmEdge static library.

Fixed issues:

  • Fixed WASI issues.
    • Fixed the leaking information about the host STDIN, STDOUT, and STDERR after getting the filestat.
    • Fixed the lookup of symbolic link at path_filestat_set_times.
    • Fixed open for the wchar path issue on windows.
  • Fixed WASI-NN issues.
    • Fixed the definition of wasi_nn::TensorType to prevent from comparing with dirty data.
  • Fixed WASI-Crypto issues.
    • Fixed the keypair_generate for rsa-pss.
    • Fixed the keypair_import read pem as pkcs8.
  • Fixed WASI-Socket issues.
    • Fixed the buffer size of sock_getpeeraddr.
  • Fixed the lost intrinsics table in AOT mode when using the WasmEdge C API.
  • Fixed the implementation in threads proposal.
    • Fixed the error in atomic.nofify and atomic.wait instructions.
    • Fixed the decoding of atomic.fence instruction.
    • Corrected the error message of waiting on unshared memory.

Refactor:

  • Refactored the implementation of number loading in the file manager.
    • Supported s33 and sn loading and decoding.
  • Refactored the WasmEdge::ValType.
    • Removed the WasmEdge::ValType::None.
    • Used the flag in WasmEdge::BlockType for supporting the type index.
    • Removed the WasmEdge::Validator::VType and used the WasmEdge::ValType instead.

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:

  • Updated the WASM spec tests to the date 2022/12/15.
  • Added the plug-in unit tests on Linux platforms.
