+
+Hello and welcome to another issue of *This Week in Rust and WebAssembly*!
+
+[Rust](https://rust-lang.org) is a systems language pursuing the trifecta:
+safety, concurrency, and speed.
+
+[WebAssembly](http://webassembly.org) is a stack-based virtual machine and
+instruction set. It is fast, safe, portable, and part of the open Web
+platform. By compiling to WebAssembly, we can run Rust code on the Web!
+
+This is a weekly summary of Rust and WebAssembly's progress and community.

+* @alexcrichton [upgraded the
+  template](https://github.com/rustwasm/rust-webpack-template/pull/120) to the
+  Rust 2018 edition.

+  🎉**](https://github.com/rustwasm/wasm-bindgen/blob/master/CHANGELOG.md#0239)
+* @c410-f3r made `wasm-bindgen`'s generated TypeScript interfaces' functions'

+  source](https://github.com/rustwasm/wasm-bindgen/pull/1344) instead of being
+  generated symbols.
+* @ibaryshnikov [cleaned up](https://github.com/rustwasm/wasm-bindgen/pull/1336)
+  our Web GL example.

+  errors](https://github.com/rustwasm/wasm-bindgen/pull/1372) in documentation
+  for `Int32Array` and `Uint32Array`
+* @RReverser [cleaned up and de-duplicated our binding
+  definitions](https://github.com/rustwasm/wasm-bindgen/pull/1371) to the

+* @alexcrichton [started migrating `wasm-pack`'s CLI
+  output](https://github.com/rustwasm/wasm-pack/pull/547) towards our 1.0 vision
