Neo SPCC updates NeoGo to v0.110.0 with TestNet state fix

NeoSPCC has released v0.110.0 of the NeoGo node and SDK, introducing new features such as the NeoFS state fetcher service and implementing several bug fixes.

State divergence fix

A divergence in the blockchain state was identified at block height 6,701,925 on TestNet, affecting node synchronization. The bug stemmed from cache persistence and state sync errors. To resolve this, v0.110.0 introduces several fixes, including MPT initialization safeguards, improved intermediate state persistence, and corrected block-height initialization logic.

TestNet node operators must either resync their database or reset to block 6,701,924 before restarting with v0.110.0 to avoid inconsistent behavior. MainNet nodes are not affected and do not require resynchronization.

New services and settings

v0.110.0 also introduces a NeoFSStateFetcher service, enabling contract storage synchronization from NeoFS snapshot data at a chosen block height. This feature supports more efficient state bootstrapping.

Support for the upcoming Faun hardfork has also been added in preview mode in order to streamline the RPC client upgrade. No changes are currently included.

Developers may now configure a BroadcastTxsBatchDelay setting to control how long the node collects P2P transactions before broadcasting them in a batch.

Other improvements

The compiler now supports slice expressions for string types. The node also adds support for the ArchivalNode feature, refactors parts of the codebase to rely on native Go functions, and adopts the recently introduced NeoFS Search V2 API.
