older

  • BinaryenSetFunctionTable in the C API no longer accepts an array of functions, instead it accepts an array of function names, const char** funcNames. Previously, you could not include imported functions because they are of type BinaryenImportRef instead of BinaryenFunctionRef. #1650

  • BinaryenSetFunctionTable in the C API now expects the initial and maximum table size as additional parameters, like BinaryenSetMemory does for pages, so tables can be grown dynamically. #1687

  • Add shared parameters to BinaryenAddMemoryImport and BinaryenSetMemory, to support a shared memory. #1686
