   This enables writing upgradeable contracts using

 ### Added
 - Added support for wildcard selectors ‒ [#1020](https://github.com/paritytech/ink/pull/1020).
     - This enables writing upgradeable smart contracts using the proxy/forward pattern.
-      We added a new example to illustrate this ‒ the [proxy](https://github.com/paritytech/ink/tree/master/examples/proxy) example.
     - Annotating a wildcard selector in traits is not supported.
 - The ink! codegen now heavily relies on static type information based on traits defined in `ink_lang` ‒ [#665](https://github.com/paritytech/ink/pull/665).
     - Some of those traits and their carried information can be used for static reflection of ink!
