 Pygolang change history
 -----------------------
 
+0.1 (2022-01-26)
+~~~~~~~~~~~~~~~~
+
+- Add `os.signal` package that provides signal handing via nogil channels. This
+  allows to build concurrent systems without limitation of Python's standard
+  `signal` module: signal delivery is not delayed, potentially indefinitely, if
+  main thread is blocked or is busy doing any non-Python work (`commit 1`__, 2__, 3__, `example usage`__).
