+# 📝 Release notes
+
+## 0.6.0
+
+*Unreleased*
+
+- [Improve macro performance][ad3cb1a1]. Improves performance of the macro
+  particularly when concatenating a large number of strs/slices. This change
+  requires the MSRV to be increased to Rust 1.66.
+
+[ad3cb1a1]: https://github.com/rossmacarthur/constcat/commit/ad3cb1a15bd5c2b718b60f8da15b2e943c645312
+
+## 0.5.1
+
+*October 5th, 2024*
+
+- [Reduce MSRV to Rust 1.60][fffa1fb8]. Removes usage of `MaybeUninit::zeroed()`
+  which lowers the MSRV to Rust 1.60.

+
+## 0.5.0
+
+*February 29th, 2024*
+
+- [Allow slice concatenation without initial value][d0ceefed]. This change
+  removes the need to add the initializer for non-number types when calling
+  `concat_slices!`. Instead of having to write something like this:
+  ```rust
+  concat_slices!([(0, 0, 0); (u8, u8, u8)]: /* ... */);
+  ```
+  You can just write
+  ```rust
+  concat_slices!([(u8, u8, u8)]: /* ... */);
+  ```
