[1.1.0] - 2023-04-19

⚡️ Breaking changes

• reply is now a method of Contract instead of global context and changed it's behavior if storage reserve is non-zero in contract.
• Logical expressions are now calculated differently: && now does not execute right expression if left is false and || does not execute right expression if left is true. Before it was executed in any case. This change is made in attempt to reduce unexpected behavior.
• OwnableTransferable is now sends response to the sender.
• overwrites was renamed to override
• Deployable trait now sends non-bounceable notifications instead of bounceable ones.

• sha256 hashing
• forward and notify functions that can be used to send messages to other contracts using remaining value of incoming message
• virtual and abstract constants that can be shared between traits
• storageReserve constant in every contract that can be used to reserve some storage space by any trait
• abstract functions that can be implemented in contracts
• FactoryDeployable trait for deploying from factory contract
• @stdlib/dns for easier DNS resolution
• Opt-in external message support
• Typed bounce receiver and bounce<T> type modifier
