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.

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.
