 # Phony for Kahlan changelog
 
-## Next release
+## 0.3.0 (2017-09-29)
+
+This release uses *Phony* `2.x` under the hood. Check out the
+[migration guide][migration-2] for *Phony* `2.x`, which also applies to this
+release.
 
 - **[BC BREAK]** HHVM is no longer supported ([#216], [#219]).
 - **[BC BREAK]** Removed `inOrderSequence`, `checkInOrderSequence`,
   `anyOrderSequence`, and `checkAnyOrderSequence` from the facade ([#215]).
+- **[BC BREAK]** Stubs created outside of a mock now have their "self" value set
+  to the stub itself, instead of the stubbed callback ([#226]).
 - **[NEW]** Implemented `anInstanceOf()` ([#220]).
 - **[NEW]** Implemented `emptyValue()` ([#218]).
 - **[IMPROVED]** Support for PHP 7.2 features, including the `object` typehint
   ([#224]).
+- **[IMPROVED]** Improved the error message produced when a default return value
+  cannot be produced, because the return type is a final class ([#228]).
 - **[IMPROVED]** Support for the PHP 7.1 `iterable` typehint in automatically
   injected suites and tests.
 - **[IMPROVED]** Reduced the amount of output generated when mocks, stubs, and
   spies are encountered by `var_dump()` ([#223]).
