We're rolling out a large set of updates including all of Neo 3.7.4 protocol changes: native contracts update functionality and extended native contract APIs united under the upcoming Cockatrice hardfork. For smart contract developers an ability to generate smart contract bindings with dynamic hash is supported as well as a number of useful extensions for unwrap package, compatible NNS smart contract RPC binding and a lot of other handy enhancements. This release also includes a couple of severe regression bug fixes affecting the node state. As a bonus of fixing a wide range of failing tests, we've refactored the node services start and shutdown procedures to make it more stable. This version drops support for Go 1.19 and requires 1.20+ to build (with Go 1.22 supported).

Notice that this release requires full node resynchronization for both mainnet and testnet nodes. Please pay special attention to the Cockatrice hardfork schedule and check your configurations. It should be configured for 3967000 of T5 testnet and 5450000 of mainnet. To ensure compatibility your node must be configured appropriately.

New features:
