All of the protocol changes are implemented there with the main one +being the Aspidochelone hardfork that will happen on mainnet +soon. Compatibility is confirmed for current T5 testnet and mainnet, but this +version requires a resynchronization so schedule your updates accordingly. + +But it's not just about the protocol changes, this release introduces an +ability to perform historic invocations via RPC for nodes that store old MPT +data. Using `invokefunctionhistoric` you can perform some invocation with the +chain state at the given height, retreiving old balances, ownership data or +anything else you might be interested in. + +Please also pay attention to configuration files used by your node, mainnet +ones must have Aspidochelone hardfork enabled at height 1730000 to be +compatible and T5 testnet enables it at height 210000. T5 testnet is different +from T4, it uses different magic number, different seed nodes different +protocol configuration settings. 0.99.0 won't work for T4 testnet, use 0.98.5 +for it. + +New features: + * new methods in native contracts: + -
