+### Enhancements

+* Implemented `PartialEq` for `DynIden`, `SimpleExpr` and related types https://github.com/SeaQL/sea-query/pull/620

 ### Breaking changes
 
 * Removed `Expr::tbl`, `Expr::greater_than`, `Expr::greater_or_equal`, `Expr::less_than`, `Expr::less_or_equal`, `Expr::into_simple_expr` https://github.com/SeaQL/sea-query/pull/551

 * `OnConflict::values` and `OnConflict::update_columns` will append the new values keeping the old values intact instead of erasing them https://github.com/SeaQL/sea-query/pull/609
+* As part of https://github.com/SeaQL/sea-query/pull/620, `SeaRc` now becomes a wrapper type.
+If you used `SeaRc` for something other than `dyn Iden`, you now have to use `RcOrArc`.
+However be reminded that it is not an intended use of the API anyway.
+```rust
+// new definition
+struct SeaRc<I>(RcOrArc<I>);
+// remains unchanged
+type DynIden = SeaRc<dyn Iden>;
+
+// if you did:
+let _: DynIden = Rc::new(Alias::new("char"));
+// replace with:
+let _: DynIden = SeaRc::new(Alias::new("char"));
+```
