Standalone operators can now disable module-originated HTTP requests with the [module-http] enabled = false configuration setting. This provides an explicit deployment-level control for environments where modules should not be allowed to access external HTTP services.

(#5774)

spacetime init and spacetime dev now choose a compatible .NET target based on the host OS: .NET 10 on Windows and Linux, and .NET 8 on macOS. C# build, generation, development, and publish commands now report incompatible host and .NET combinations clearly. This also fixes duplicate package references in .NET 8 NativeAOT module projects.

(#5571)

Commitlog segment rotation and compression now durably sync newly installed segment files and their containing directory. Previously, a power loss in a narrow window after a segment was renamed could lose transactions that had already been acknowledged as durable; compression could similarly replace a durable segment without fully persisting the replacement. The updated persistence path preserves the confirmed-read durability guarantee across crashes.

(#5785)

The TypeScript SDK now reuses the identity token issued during a first-time anonymous connection when automatically reconnecting. Previously, if the initial connection was created without a stored token, a later reconnect could request a new anonymous identity and silently lose access to data associated with the original identity. Explicit connection rebuilds can still change identity as intended.

(#5761)

Any client data now counts as WebSocket activity and extends the idle deadline, rather than requiring a pong specifically. Idle connections are closed with a proper close handshake and an idle timeout reason, with a grace period before forced teardown. This improves liveness detection and gives clients a clear reason for disconnection.

(#5517)

C++ multi-column index scans now correctly support exact prefixes followed by an optional terminal range across indexes with three or more columns. Invalid queries with a non-terminal range are rejected at compile time, and index iterator buffering now handles large result payloads correctly.

(#5565)

The C# SDK now resets generated generic table-handle static state through a non-generic Unity initialization path, fixing Play Mode behavior when domain reload is disabled. The missing IEnumerator import used by Unity WebGL message parsing has also been restored.

(#5738, #5792)

The C# SDK now clears outstanding request tracking and pending operations when connections fail, removes failed subscriptions, and rejects one-off queries immediately when disconnected. This prevents stale state and memory from accumulating across error and reconnect paths.
