+## 0.13.0
+
+Unreleased
+
+### Added
+
+* Lots of documentation of `wasmtime` has been updated. Be sure to check out the
+  [book](https://bytecodealliance.github.io/wasmtime/) and [API
+  documentation](https://bytecodealliance.github.io/wasmtime/api/wasmtime/)!
+
+* All wasmtime example programs are now in a top-level `examples` directory and
+  are available in both C and Rust.
+  [#1286](https://github.com/bytecodealliance/wasmtime/pull/1286)
+
+* A `wasmtime::Linker` type was added to conveniently link link wasm modules
+  together and create instances that reference one another.
+  [#1384](https://github.com/bytecodealliance/wasmtime/pull/1384)
+
+* Wasmtime now has "jitdump" support enabled by default which allows [profiling
+  wasm code on linux][jitdump].
+  [#1310](https://github.com/bytecodealliance/wasmtime/pull/1310)
+
+* The `wasmtime::Caller` type now exists as a first-class way to access the
+  caller's exports, namely memory, when implementing host APIs. This can be the
+  first argument of functions defined with `Func::new` or `Func::wrap` which
+  allows easily implementing methods which take a pointer into wasm memory.
+  [#1290](https://github.com/bytecodealliance/wasmtime/pull/1290)
+
+* The bulk memory proposal has been fully implemented.
+  [#1264](https://github.com/bytecodealliance/wasmtime/pull/1264)
+  [#976](https://github.com/bytecodealliance/wasmtime/pull/976)
+
+* Virtual file support has been added to `wasi-common`.
+  [#701](https://github.com/bytecodealliance/wasmtime/pull/701)
+
+* The C API has been enhanced with a Wasmtime-specific `wasmtime_wat2wasm` to
+  parse `*.wat` files via the C API.
+  [#1206](https://github.com/bytecodealliance/wasmtime/pull/1206)
+
+[jitdump]: https://bytecodealliance.github.io/wasmtime/examples-profiling.html
+
+### Changed
+
+* The `wast` and `wasm2obj` standalone binaries have been removed. They're
+  available via the `wasmtime wast` and `wasmtime wasm2obj` subcommands.
+  [#1372](https://github.com/bytecodealliance/wasmtime/pull/1372)
+
+* The `wasi-common` crate now uses the new `wiggle` crate to auto-generate a
+  trait which is implemented for the current wasi snapshot.
+  [#1202](https://github.com/bytecodealliance/wasmtime/pull/1202)
+
+* Wasmtime no longer has a dependency on a C++ compiler.
+  [#1365](https://github.com/bytecodealliance/wasmtime/pull/1365)
+
+* The `Func::wrapN` APIs have been consolidated into one `Func::wrap` API.
+  [#1363](https://github.com/bytecodealliance/wasmtime/pull/1363)
+
+* The `Callable` trait has been removed and now `Func::new` takes a closure
+  directly.
+  [#1363](https://github.com/bytecodealliance/wasmtime/pull/1363)
+
+* The Cranelift repository has been merged into the Wasmtime repository.
+
+* Support for interface types has been temporarily removed.
+  [#1292](https://github.com/bytecodealliance/wasmtime/pull/1292)
+
+* The exit code of the `wasmtime` CLI has changed if the program traps.
+  [#1274](https://github.com/bytecodealliance/wasmtime/pull/1274)
+
+* The `wasmtime` CLI now logs to stderr by default and the `-d` flag has been
+  renamed to `--log-to-file`.
+  [#1266](https://github.com/bytecodealliance/wasmtime/pull/1266)
+
+* Values cannot cross `Store` objects, meaning you can't instantiate a module
+  with values from different stores nor pass values from different stores into
+  methods.
+  [#1016](https://github.com/bytecodealliance/wasmtime/pull/1016)
