 -----------------------
 
+0.0.6 (2020-02-28)
+~~~~~~~~~~~~~~~~~~
+
+- Provide support for error chaining. In concurrent systems
+  operational stack generally differs from execution code flow, which makes
+  code stack traces significantly less useful to understand an error.
+  Error chaining gives ability to build operational
+  error stack and to inspect resulting errors.
+  (`commit 1`__, 2__, 3__, 4__, 5__, 6__, `overview 1`__, `overview 2`__).

+
+- Provide `unicode` ↔ `bytes` conversion:
+  `b(obj)` converts str/unicode/bytes obj to UTF-8 encoded bytestring, while
+  `u(obj)` converts str/unicode/bytes obj to unicode string. The conversion in
+  both encoding and decoding never fails and never looses information:
+  `b(u(·))` and `u(b(·))` are always identity for bytes and unicode
+  correspondingly, even if bytes input is not valid UTF-8.
