## 0.102.0 "Yarborough" (TODO Jul 2023)
Long-awaited 3.6.0-compatible version of NeoGo with all the appropriate protocol
updates and a set of tasty improvements and bug fixes. This release delivers a
couple of major features which are extremely useful for smart contract developers.
The first one is the interoperability support of group operations over BLS12-381
elliptic curve points which makes it possible to implement Groth16 proving system
on the top of the Neo blockchain. Another one is the improvement of RPC bindings
generator: automatic contract event wrappers and dynamic contract hashes are
properly supported from now. Also, a severe dBFT vulnerability that may cause
rush in blocks acceptance triggered by a presence of a single misconfigured
consensus node was fixed.
This is also the first version that supports Go 1.20 (generics in smart contracts
are not supported yet, but scheduled for the further releases). Support for
Go 1.17 is removed at the same time, so you need Go 1.18+ to build NeoGo now.
The users of smart contract utilities and RPC-related Prometheus metrics are
welcomed to take a look at the deprecated APIs removal.
Another vital change is TODO hardfork that will happen on mainnet and T5 testnet
soon. Compatibility is confirmed for current T5 testnet and mainnet, but this
version requires a resynchronization so schedule your updates accordingly.
Important note for node operators: please, consider that configuration file used
by your mainnet node contains not only Aspidochelone hardfork enabled at height
1730000, but also TODO hardfork enabled at height TODO. T5 testnet is continuing
to be supported, thus ensure that testnet configuration file includes TODO
hardfork enabled at height TODO.
