Upgrading?
AI Summary
The compiler now supports `__force` and `__export` decorators to control JavaScript library symbol inclusion and export visibility. It also upgrades GLFW to 3.5.1, updates FreeType to 2.14.3, and separates Wasm exception linking from C++ linking.
Key Highlights
- `__force` and `__export` decorators added
- GLFW port upgraded to 3.5.1
- Wasm EH runtime links independently of C++
- FreeType updated to 2.14.3
- Minimum Safari version raised to 15.0
New Features
- Control over library symbol inclusion via decorators
- Non-C++ frontends can link Wasm EH without -sDEFAULT_TO_CXX
Full Release Notes
## What's Changed - JavaScript library symbols can now use the `__force` and `__export` decorators to control inclusion and export visibility. (#27436) - contrib.glfw3 port upgraded to use the latest version of GLFW 3.5.1 (#27508) - `-fwasm-exceptions` now links the Wasm EH runtime (libunwind and the `__cpp_exception` tag) independently of C++ linking, so Wasm EH objects from non-C++ frontends (e.g. rustc, which links via `emcc`) link without requiring `em++` or `-sDEFAULT_TO_CXX`. (#27496) - FreeType was updated to 2.14.3 (#27518) - The oldest supported Safari version (`MIN_SAFARI_VERSION`) was raised from 14.1 to 15.0, making 15.0 the minimum version that can be targeted. This allows assuming `bulk-memory`, `nontrapping-fptoint`, and `WASM_BIGINT` (`JS_BIGINT_INTEGRATION`) are universally available across all supported engines, and removes legacy JS polyfills and Binaryen lowering passes.
