Wasmer

Fixed

- [1294](https://github.com/wasmerio/wasmer/pull/1294) Fix bug related to system calls in WASI that rely on reading from WasmPtrs as arrays of length 0. `WasmPtr` will now succeed on length 0 arrays again.

Fixed

- [1291](https://github.com/wasmerio/wasmer/pull/1291) Fix installation packaging script to package the `wax` command.

Added
- [1286](https://github.com/wasmerio/wasmer/pull/1286) Updated Windows Wasmer icons. Add wax
- [1284](https://github.com/wasmerio/wasmer/pull/1284) Implement string and memory instructions in `wasmer-interface-types`

Fixed
- [1272](https://github.com/wasmerio/wasmer/pull/1272) Fix off-by-one error bug when accessing memory with a `WasmPtr` that contains the last valid byte of memory. Also changes the behavior of `WasmPtr<T, Array>` with a length of 0 and `WasmPtr<T>` where `std::mem::size_of::<T>()` is 0 to always return `None`

- [1263](https://github.com/wasmerio/wasmer/pull/1263) Changed the behavior of some WASI syscalls to now handle preopened directories more properly. Changed default `--debug` logging to only show Wasmer-related messages.
- [1217](https://github.com/wasmerio/wasmer/pull/1217) Polymorphic host functions based on dynamic trampoline generation.
- [1252](https://github.com/wasmerio/wasmer/pull/1252) Allow `/` in wasi `--mapdir` wasm path.
- [1212](https://github.com/wasmerio/wasmer/pull/1212) Add support for GDB JIT debugging:
- Add `--generate-debug-info` and `-g` flags to `wasmer run` to generate debug information during compilation. The debug info is passed via the GDB JIT interface to a debugger to allow source-level debugging of Wasm files. Currently only available on clif-backend.
- Break public middleware APIs: there is now a `source_loc` parameter that should be passed through if applicable.
- Break compiler trait methods such as `feed_local`, `feed_event` as well as `ModuleCodeGenerator::finalize`.

- [1245](https://github.com/wasmerio/wasmer/pull/1245) Use Ubuntu 16.04 in CI so that we use an earlier version of GLIBC.
- [1234](https://github.com/wasmerio/wasmer/pull/1234) Check for unused excluded spectest failures.
- [1232](https://github.com/wasmerio/wasmer/pull/1232) `wasmer-interface-types` has a WAT decoder.

- [1233](https://github.com/wasmerio/wasmer/pull/1233) Improved Wasmer C API release artifacts.
- [1216](https://github.com/wasmerio/wasmer/pull/1216) `wasmer-interface-types` receives a binary encoder.
- [1228](https://github.com/wasmerio/wasmer/pull/1228) Singlepass cleanup: Resolve several FIXMEs and remove protect_unix.
- [1218](https://github.com/wasmerio/wasmer/pull/1218) Enable Cranelift verifier in debug mode. Fix bug with table indices being the wrong type.
- [787](https://github.com/wasmerio/wasmer/pull/787) New crate `wasmer-interface-types` to implement WebAssembly Interface Types.
- [1213](https://github.com/wasmerio/wasmer/pull/1213) Fixed WASI `fdstat` to detect `isatty` properly.
- [1192](https://github.com/wasmerio/wasmer/pull/1192) Use `ExceptionCode` for error representation.
- [1191](https://github.com/wasmerio/wasmer/pull/1191) Fix singlepass miscompilation on `Operator::CallIndirect`.
- [1180](https://github.com/wasmerio/wasmer/pull/1180) Fix compilation for target `x86_64-unknown-linux-musl`.
- [1170](https://github.com/wasmerio/wasmer/pull/1170) Improve the WasiFs builder API with convenience methods for overriding stdin, stdout, and stderr as well as a new sub-builder for controlling the permissions and properties of preopened directories. Also breaks that implementations of `WasiFile` must be `Send` -- please file an issue if this change causes you any issues.
- [1161](https://github.com/wasmerio/wasmer/pull/1161) Require imported functions to be `Send`. This is a breaking change that fixes a soundness issue in the API.
