 Current Trunk
 -------------
-
+ - Remove fastcomp's implementation of Asyncify. This has been deprecated for
+   a long time, since we added Emterpreter-Async, and now we have a new Asyncify
+   implementation in the upstream wasm backend. It is recommended to upgrade to
+   the upstream backend and use Asyncify there if you need it. (If you do still
+   need the older version, you can use 1.38.40.)
+
+v.1.38.40: 07/24/2019
+---------------------
+ - LLVM backend pthread builds no longer use external memory initialization
+   files, replacing them with passive data segments.
+ - LLVM backend now supports thread local storage via the C extension `__thread`
+   and C11/C++11 keyword `thread_local`. (#8976)
+ - Internal API change: Move read, readAsync, readBinary, setWindowTitle from
+   the Module object to normal JS variables. If you use those internal APIs,
+   you must change Module.readAsync()/Module['readAsync']() to readAsync().
+   Note that read is also renamed to read_ (since "read" is an API call in
+   the SpiderMonkey shell). In builds with ASSERTIONS an error message is
+   shown about the API change. This change allows better JS minification
+   (the names read, readAsync etc. can be minified, and if the variables are
+   not used they can be removed entirely). Defining these APIs on Module
+   (which was never documented or intended, but happened to work) is also
+   no longer allowed (but you can override read_ etc. from JS).
+
+v1.38.39: 07/16/2019
+--------------------
  - Add support for [address sanitizer](https://clang.llvm.org/docs/AddressSanitizer.html). (#8884)
    - Currently, only supports one thread without dynamic linking.
+ - Rename Bysyncify (the name used during development) to Asyncify. This keeps the name consistent
+   with the old ASYNCIFY flag, no need for a new one, as they do basically the same thing.
 
 v1.38.38: 07/08/2019
 --------------------
-
  - Add support for standalone [leak sanitizer](https://clang.llvm.org/docs/LeakSanitizer.html). (#8711)
 
 v1.38.37: 06/26/2019
 --------------------
-
  - Set ENV['LANG'] following the user's preferred language (HTTP Accept-Language / navigator.languages[0])
  - `emscripten_run_script_string` now returns C `NULL` instead of the string `null`
    or `undefined` when the result of the `eval` is JavaScript `null` or `undefined`.
