Roadmap for neo-go
This defines approximate plan of neo-go releases and key features planned for them. Things can change if there is a need to push a bugfix or some critical functionality.
Versions 0.7X.Y (as needed)
- Neo 2.0 support (bug fixes, minor functionality additions)
Version 0.102.1 (~October 2023)
- bug fixes
Version 0.103.0 (~November 2023)
- extended data types for iterators to be used by RPC wrapper generator
- RPC subscription extensions
Version 1.0 (2023, TBD)
- stable version
Deprecated functionality
As the node and the protocol evolve some external APIs can change. Usually we try keeping backwards compatibility for some time (like half a year) unless it's impossible to do for some reason. But eventually old APIs/commands/configurations will be removed and here is a list of scheduled breaking changes. Consider changing your code/scripts/configurations if you're using anything mentioned here.
Direct UnlockWallet consensus configuration
Top-level UnlockWallet section in ApplicationConfiguration was used as an implicit consensus service configuration, now this setting (with Enabled flag) is moved into a section of its own (Consensus). Old configurations are still supported, but this support will eventually be removed.
Removal of this compatibility code is scheduled for May-June 2023 (~0.103.0 release).
Node-specific configuration moved from Protocol to Application
GarbageCollectionPeriod, KeepOnlyLatestState, RemoveUntraceableBlocks, SaveStorageBatch and VerifyBlocks settings were moved from ProtocolConfiguration to ApplicationConfiguration in version 0.100.0. Old configurations are still supported, except for VerifyBlocks which is replaced by SkipBlockVerification with inverted meaning (and hence an inverted default) for security reasons.
Removal of these options from ProtocolConfiguration is scheduled for May-June 2023 (~0.103.0 release).
GetPeers RPC server response type changes and RPC client support
GetPeers RPC command returns a list of Peers where the port type has changed from string to uint16 to match C#. The RPC client currently supports unmarshalling both formats.
Removal of Peer unmarshalling with string based ports is scheduled for ~September 2023 (~0.105.0 release).
NEOBalance from stack item
We check struct items count before convert LastGasPerVote to let RPC client be compatible with old versions.
Removal of this compatiblility code is scheduled for Sep-Oct 2023.
serv_node_version Prometheus gauge metric
This metric is replaced by the new neogo_version and server_id Prometheus gauge
metrics with proper version formatting. neogo_version contains NeoGo version
hidden under version label and server_id contains network server ID hidden
under server_id label.
Removal of serv_node_version is scheduled for Sep-Oct 2023 (~0.105.0 release).
RPC error codes returned by old versions and C#-nodes
NeoGo retains certain deprecated error codes: neorpc.ErrCompatGeneric,
neorpc.ErrCompatNoOpenedWallet. They returned by nodes not compliant with the
neo-project/proposals#156 (NeoGo pre-0.102.0 and all known C# versions).
Removal of the deprecated RPC error codes is planned once all nodes adopt the new error standard.
