0.5.0

This version of Wasmer ships with a much more stable version of WASI, supporting environment variables and directory mapping. It also ships with wapm 0.3.0 that includes support for package signing and contracts.
Apart of the fixes we improved the Emscripten integration, that now is able to run python and openssl.

0.4.0 (wasmer + wapm)

Wasmer now ships with wapm 🎉.
WAPM is a Package Manager for WebAssembly that will improve your experience for installing, using and publishing WebAssembly modules. Here's a video showcasing it: https://www.youtube.com/watch?v=qDRcHIBFu0c

Apart of shipping with wapm, the stability of the runtime has been improved significantly and support for WASI is more mature.

Changelog

#383 Hook up wasi exit code to wasmer cli.
#382 Improve error message on --backend flag to only suggest currently enabled backends
#381 Allow retrieving propagated user errors.
#379 Fix small return types from imported functions.
#371 Add more Debug impl for WASI types
#368 Fix issue with write buffering
#343 Implement preopened files for WASI and fix aligment issue when accessing WASI memory
#367 Add caching support to the LLVM backend.
#366 Remove UserTrapper trait to fix #365.
#348 Refactor internal runtime ↔️ backend abstraction.
#355 Misc changes to Cargo.tomls for publishing
#352 Bump version numbers to 0.3.0
#351 Add hidden option to specify wasm program name (can be used to improve error messages)
#350 Enforce that CHANGELOG.md is updated through CI.
#349 Add CHANGELOG.md.

0.3.0

Wasmer now supports WASI 🎉.
The emscripten implementation has improved vastly, and now Wasmer can run PHP, SQLite and Lua (check them on the examples dir on this repo)

We also improved the APIs and shipped tons of bug fixes and improvements.

0.2.0

53c8603

0.2.0

The version 0.2.0 moves the WebAssembly wasmer runtime forward making it more stable, with a more mature API and preparing the software to be ready in production environments.
It also accelerates the startup time when running a WebAssembly module by an order of magnitude.

This version also ships with experimental Windows support (all WebAssembly spectests pass, emscripting bindings are on the works).

Changelog

Completely refactored our codebase, moving the runtime, Cranelift backend and emscripten into it's own isolated libs #80
Added Cache #134 #198 #200, so WebAssembly compiled modules can be loaded much faster (100x speedup on compile time)
Added integration tests #109 #91
Improved support for Windows #51 #94 #143 #144 #138 #175
Improved function signature checks #155
Improved imports API #120 #130
Naive short circuiting implementation for user panics and results #167
Improved traps support #103
Use parallel compilation for cranelift backend #209
Improved debug #61 #67 #129 #204
Added benchmark runner #201

Breaking changes

The breaking changes affect mainly to other libraries that were depending in any of the crates for embedding Wasmer in their systems.
You can check an example PR with all the changes included here: https://github.com/wasmerio/wasmer-rust-example/pull/5/files

Summary:

Now the imported functions take Ctx as first argument instead of the last one #171

// Previous (0.1.x)
fn print_num(n: i32, ctx: &mut vm::Ctx) {
    println!("print_num({})", n);
}

// Now (>= 0.2.0)
fn print_num(ctx: &mut vm::Ctx, n: i32) {
    println!("print_num({})", n);
}

The imported function in imports! should use now the func! macro.

// Previous (0.1.x)
let import_object = imports! {
    "env" => {
        "print_num" => print_num<[i32] -> []>,
    },
};

// Now (>= 0.2.0)
let import_object = imports! {
    "env" => {
        // The func! macro will automatically detect the signature
        "print_num" => func!(print_num),
    },
};

Access to memory slices is now safe

// Previous (0.1.x)
let memory = ctx.memory(0);
let str_slice = &memory[ptr as usize..(ptr + len) as usize];


// Now (>= 0.2.0)
let memory = ctx.memory(0);
let str_slice: Vec<_> = memory.view()[ptr as usize..(ptr + len) as usize].iter().map(|cell| cell.get()).collect();
