+2.0.28
 ------
 - Added some support for signal handling libc functions (raise, kill,
   sigaction, sigpending, etc).  We still don't have a way to deliver signals from
   the outside but these at least now work for sending signals to the current
   thread (JS context) (#14883).

+2.0.27 - 08/12/2021
+-------------------
 - Added `EM_ASYNC_JS` macro - similar to `EM_JS`, but allows using `await`
   inside the JS block and automatically integrates with Asyncify without
   the need for listing the declared function in `ASYNCIFY_IMPORTS` (#9709).
