Project: WasmEdge Runtime (Runtime / Container Runtime)
File: Changelog.md

Breaking changes: [Version]: Bump the version of the WasmEdge shared library. Due to the breaking change of API, bump the `SOVERSION` to `0.1.0`. Due to the breaking change of API, bump the plug-in `API_VERSION` to `3`. [C API]: Changes for applying Typed Function References Proposal. New `WasmEdgeValType` structure for replacing `enum WasmEdgeValType`. Merge the `enum WasmEdgeValType` and `enum WasmEdgeRefType` into the `enum WasmEdge_TypeCode`. Refactored the error code. The error code number may different from previous versions. Extend the error code to 2 bytes. Updated the related APIs for using `enum WasmEdge_ValType` as parameters. `WasmEdge_FunctionTypeCreate()` `WasmEdge_FunctionTypeGetParameters()` `WasmEdge_FunctionTypeGetReturns()` `WasmEdge_TableTypeCreate()` `WasmEdge_TableTypeGetRefType()` `WasmEdge_GlobalTypeCreate()` `WasmEdge_GlobalTypeGetValType()` Removed `WasmEdge_ValueGenNullRef()` API. Due to non-defaultable values after this proposal, the following APIs return the result instead of void. `WasmEdge_GlobalInstanceSetValue()` Introduced the `WasmEdge_Bytes` structure. This structure is for packaging the `uint8_t` buffers. The old `FromBuffer` related APIs will be replaced by the corresponding APIs in the future versions. `WasmEdgeCompilerCompileFromBytes()` API has the same function as `WasmEdgeCompilerCompileFromBuffer()` and will replace it in the future. `WasmEdgeLoaderParseFromBytes()` API has the same function as `WasmEdgeLoaderParseFromBuffer()` and will replace it in the future. `WasmEdgeVMRegisterModuleFromBytes()` API has the same function as `WasmEdgeVMRegisterModuleFromBuffer()` and will replace it in the future. `WasmEdgeVMRunWasmFromBytes()` API has the same function as `WasmEdgeVMRunWasmFromBuffer()` and will replace it in the future. `WasmEdgeVMAsyncRunWasmFromBytes()` API has the same function as `WasmEdgeVMAsyncRunWasmFromBuffer()` and will replace it in the future. `WasmEdgeVMLoadWasmFromBytes()` API has the same function as `WasmEdgeVMLoadWasmFromBuffer()` and will replace it in the future. New APIs for WASM Exception-Handling proposal. Added the `WasmEdge_TagTypeContext` struct. Added the `WasmEdge_TagInstanceContext` struct. Added the `WasmEdge_TagTypeGetFunctionType()` API for retrieving the function type from a tag type. Added the `WasmEdge_ImportTypeGetTagType()` API for retrieving the tag type from an import type. Added the `WasmEdge_ExportTypeGetTagType()` API for retrieving the tag type from an export type. Added the `WasmEdge_ModuleInstanceFindTag()` API for finding an exported tag instance from a module instance. Added the `WasmEdgeModuleInstanceListTagLength()` and `WasmEdgeModuleInstanceListTag()` APIs for listing the exported tag instances of a module instance. Refactored the `OpCode` mechanism for speeding up and supporting WASM multi-bytes instruction OpCodes. Features: Bumpped `spdlog` to `v1.13.0`. Bumpped `simdjson` to `v3.9.1`. [Proposal]: Apply new propoals. Supported WASM Typed Function References proposal. Added the `WasmEdgeProposalFunctionReferences` for the configuration in WasmEdge C API. Users can use the `--enable-function-reference` to enable the proposal in `wasmedge` and `wasmedgec` tools. Supported WASM GC proposal (interpreter only). Added the `WasmEdgeProposalGC` for the configuration in WasmEdge C API. Users can use the `--enable-gc` to enable the proposal in `wasmedge` and `wasmedgec` tools. Supported WASM Exception-Handling proposal (interpreter only). Added the `WasmEdgeProposalExceptionHandling` for the configuration in WasmEdge C API. Users can use the `--enable-exception-handling` to enable the proposal in `wasmedge` and `wasmedgec` tools. This proposal supports old deprecated `try`, `catch`, and `catch_all` instructions, and will remove them in the future version. Component Model proposal (experimental, loader phase only). Added the `WasmEdgeProposalComponent` for the configuration in WasmEdge C API. Users can use the `--enable-component` to enable the proposal in `wasmedge` tool. [JIT]: Support LLVM JIT.
