+# Changelog
+
+## 0.3.0
+### Breaking changes
+* Crate has new maintainer: Wojciech Polak :hand: :tada:
+* Crate has new name, as `test-case-derive` had no meaning for `derive` part.
+* Delimiter for test case description is `;` instead of `::`.
+
+  Reason: `::` is valid part of expression and rustc treats const variable as path
+### New features
+* Upgraded syn, quote and proc-macro-2 to v1
+* Proper error propagation :tada:
+  When there is for example a typo in function body, rustc can now show location
+  of it instead of test_case location.
+* Internally for tests crate uses `cargo insta` for snapshot testing

-* Crate has new maintainer: Wojciech Polak :hand: :tada:
-* Since `0.3.0` delimiter for test case description is `;` instead of `::`.
-Reason: `::` is valid part of expression and rustc treats const variable as path
-with length 1. So usage `#[test_case(1, MY_CONST :: "my desc")]` is treated as
-`MY_CONST::"invalid because literal string cannot be part of path"`.
