+### Removed
+
+- All deprecated APIs are now removed. If you have breaking changes moving to this version,
+  downgrade to the latest 1.x.x version and use `ReplaceWith()` to smoothly migrate to the latest
+  APIs.
+- Removed any `com.composables.core` reference.
+
+### Changed
+
+- Decoupled theming from primitives. Primitives used to be themable using `LocalContentColor` and
+  `LocalTextStyle`. This was problematic as you could not easily style your primitives using a
+  different theming API (such as Material Compose). Because of this, any kind of theming is removed,
+  and the users are responsible for choosing the theming API of their choice.
