 **IMPORTANT SECURITY NOTICE**
+
 Please familiarize yourself with [the new entitlements feature](https://cadence-lang.org/docs/1.0/language/access-control#entitlements)

 If you change `pub` to `access(all)` without paying attention to potential downcasting from public interfaces, you might expose private
 functions like `withdraw` that will cause security problems for your contract.
