 | `Basilisk`      | Enables strict smart contract script check against a set of JMP instructions and against method boundaries enabled on contract deploy or update.

 | `Domovoi`       | Makes node use executing contract state for the contract call permissions check instead of the state stored in the native Management contract. In C# also makes System.Runtime.GetNotifications interop properly count stack references of notification parameters which prevents users from creating objects that exceed MaxStackSize constraint, but NeoGo has never had this bug, thus proper behaviour is preserved even before HFDomovoi. It results in the fact that some T5 testnet transactions have different ApplicationLogs compared to the C# node, but the node states match. | https://github.com/nspcc-dev/neo-go/pull/3476 <br> https://github.com/neo-project/neo/pull/3290 <br> https://github.com/nspcc-dev/neo-go/pull/3473 <br> https://github.com/neo-project/neo/pull/3290 <br> https://github.com/neo-project/neo/pull/3301 <br> https://github.com/nspcc-dev/neo-go/pull/3485 |
