+## 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.
