Breaking Changes

New Features

Implement two-level Multi-tier JIT engine: tier-up from Fast JIT to LLVM JIT to get quick cold startup and better performance Enable running mode control for runtime, wasm module instance and iwasm Implement wasi-threads feature Upgrade toolkits: upgrade to llvm-15.0, wasi-sdk-19.0, emsdk-3.1.28 and so on Port WAMR to the FreeBSD platform Refactor wasi-nn to simplify the support for multiple frameworks wasi-nn: Enable GPU support wasi-nn: Support multiple TFLite models Add WAMR API bindings in Python Add libsodium benchmark

Bug Fixes

Fix wasm-c-api import func link issue in wasm_instance_new Fix watchpoint segfault when using debug interp without server libc-wasi: Fix spurious poll timeout Fix typo verify_module in aot_compiler.c Fix failure about preopen of reactor modules Fix equal check in AOT XIP float cmp intrinsic Fix issue of resolving func name in custom name section Fix go language binding build on macos arm64 Prevent undefined behavior from c_api_func_imports == NULL Fix potential block issue in source debugger SGX IPFS: Fix a segfault and support seeking beyond the end of files while using SEEK_CUR/SEEK_END Fix undef error about WAMR_BUILD_MEMORY_PROFILING Fix jit memory overwritten after instance deinstantiate Fix stack alignment issue on ia32 Fix explicit casts and types in espidf_socket.c Fix potential integer overflow issue in wasm-c-api Fix libc-wasi build failure when using clang Fix wamrapi python binding for darwin Fix getting port issue in posix os_socket_bind Fix key error in build_llvm.py nuttx: Add missing pthread.h header Fix os_socket_addr_resolve() for IPv6 Enhance/Fix sample socket-api and workload Fix fast-jit build error Fix dead lock in source debugger fix debugger: Set termination flags also when in debug mode

Enhancements
