Features

C# NativeAOT monomorphized dispatch

Generated C# module exports now dispatch directly to statically-known generic entrypoints for reducers, procedures, HTTP handlers, views, and anonymous views when building with NativeAOT-LLVM. This eliminates virtual dispatch overhead at the module boundary and improves NativeAOT module performance.

(#5610)

MCP support on Maincloud

The SpacetimeDB MCP endpoint (/v1/mcp) is now available on Maincloud. You can connect AI agents and MCP-compatible tools directly to your Maincloud databases. This release also adds cluster-aware routing so that MCP requests sent to any node are automatically proxied to the leader replica, along with egress tracking for MCP tool calls.

(#5849, #5793)

Bug Fixes

TypeScript SDK: route mid-session websocket errors to onDisconnect

The TypeScript SDK's ws.onerror handler previously treated every websocket error as a connection failure, even on established connections. This fired onConnectError instead of onDisconnect, silently disabled the outbound send path, and left the client in a stalled state with no reconnect. Mid-session errors now close the socket and fire onDisconnect with the error, allowing existing reconnect handling to take over.

(#5707)

Fix C++ auto-increment macro symbol collisions

C++ auto-increment field macros previously used __LINE__ to generate symbols, causing collisions when two table definitions in separate files had an auto-increment field on the same line number. Macros now use table and field names to guarantee unique symbols.

(#5836)

Fix spacetime dev C# complaint on macOS

The spacetime dev command no longer incorrectly warns about C# on macOS when C# is not in use.

(#5867)
