Releases · AssemblyScript/assemblyscript

The explicit start function generated with --explicitStart has been renamed to _start (was __start) to match WASI.
The __setargc helper to set the number of arguments to a varargs call has been removed and replaced with an exported mutable global __argumentsLength. The loader has been updated accordingly.
For consistency, the loader's __getInt8Array etc. functions now copy, and new __getInt8ArrayView functions with the old behavior have been introduced.
The call_indirect builtin has been removed due to expected problems with closures.
Distribution files are now being built with ES2016 as the target, exposing ES classes instead of ES5 prototypes.

Binaryen has AssemblyScript-specific optimization passes now targeting reference counting.
Optimization pass order is no longer inherited from Binaryen but has been customized to account for AS specifics.
Tables can now be exported using the --exportTable flag.
The implementations of the Math functions exp, exp2, log, log2 and pow have been replaced with faster variants.
New standard library functions: String#toUpperCase, String#toLowerCase, String#localeCompare. TypedArray#set
The stub runtime now exports the __reset helper to clear the heap externally.
Added support for the SIMD avgr_u family of instructions.
Updated the WASI implementation to wasi_snapshot (preview1).
The type of an array literal can now be inferred from its contents.
The compiler can now detect if the entire program is acyclic (no cyclic classes), omitting unnecessary parts of the GC in this case.

And, of course, lots of fixes.
