This document outlines major changes between releases.

|

## 0.102.0 "Aberration" (06 Sep 2023)
|
||||
|
||||
Long-awaited feature-packed 3.6.0-compatible version of NeoGo with all the
|
||||
appropriate protocol updates and a set of tasty improvements and bug
|
||||
fixes. Groth16 ZKP proof checks are there for contract developers as well as
|
||||
new opcodes. A huge number of improvements went into the RPC server and
|
||||
client, new RPCs, improved contract binding generator and standardized
|
||||
extended error codes make developing dApps much easier.
|
||||
|
||||
Users of smart contract utilities and RPC-related Prometheus metrics are
|
||||
advised to take a look at the deprecated APIs removal schedule
|
||||
(ROADMAP.md). This version was delayed for quite some time (waiting for 3.6),
|
||||
so the next minor release (0.103.0) will remove a substantial amount of
|
||||
compatibility code. It's expected to be released in November with 3.6 protocol
|
||||
compatibility (3.7 cycle is likely to require more time).
|
||||
|
||||
This is also the first version that drops support for Go 1.17 and requires
|
||||
1.18+ to build (with Go 1.20 supported). Using generics in smart contracts is
|
||||
not supported yet, but some elements of this support can be implemented in
|
||||
future versions.
|
||||
|
||||
Mainnet and testnet node operators, please pay attention to the Basilisk
|
||||
hardfork schedule and check your configurations. It will happen at block
|
||||
2680000 for T5 testnet and 4120000 for mainnet. To ensure compatibility your
|
||||
node must be configured appropriately. This version requires DB
|
||||
resynchronization, so schedule your updates accordingly.
|
||||
|
||||
New features:
|
||||

|

|
||||

|
||||
* strict contract script check is back with Basilisk hardfork, it was
|
||||
previously removed in 0.101.3 for 3.5 protocol compatibility (#3056)
|
||||

|
||||
