 # Changelog
 
-## [0.1.2] - 2026-06-02
+## Unreleased
 
-- 🔧 Maintenance
+### Removed
+- **BREAKING:** Removed `Rc`, `RcStr`, `RcUtf16Str`, and all `alloc_*_rc*`
+  and `into_arena_rc*` methods. Use the `Arc` family
+  (`alloc_arc`, `alloc_str_arc`, `alloc_utf16_str_arc`, `alloc_dst_arc`,
+  `Vec::into_arena_arc`, …) or the `Box` family
+  (`alloc_box`, `alloc_str_box`, `Vec::into_arena_box`, …) instead.
