  • WASI Socket:
    • Workaround: reduce the address family size for the old API
    • fix sock opt & add BINDTODEVICE (#2454)
  • MacOS
    • Use OpenSSL 3.0 on MacOS when building the plugins.
    • Update the visibility of plugin functions.
    • Fix AOT Error on MacOS; fix #2427
      • Change enumerate attributes value to zero
      • Change import helper function to private linkage to hide symbols
      • Detect OS version
    • Fix building with statically linked LLVM-15 on MacOS.

Because the runwasi project supports both wasmtime and wasmedge, the wasmtime-fiber with different versions will make the compilation complex. To avoid this, we forked wasmtime-fiber as fiber-for-wasmedge.
    • Add a second phase mechanism to load plugins after the VM has already been built. (#2469)
  • Documents:
    • Fix the naming of the AOT wasm file.
    • Add wasmedgec use cases for a slim container.
    • Add the Kwasm document.
    • Fix HostFunction with data example (#2441)

Known issues:

  • Universal WASM format failed on macOS platforms.
    • In the current status, the universal WASM format output of the AOT compiler with the O1 or upper optimizations on MacOS platforms will cause a bus error during execution.
    • We are trying to fix this issue. For a 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.
