nexgen v0.2.10

Added

• Go system Nexus code generation supports @nexus.serialization-context helpers and emits an operation registry keyed by wire service and operation names, allowing the SDK to select the serialization context for an operation's nested user payloads.
• Generated Go model types expose value-receiver getters for exported fields, allowing support packages to consume models through interfaces without importing the generated package.
• Go WIT function references support go-value-type / go-args-type representation overrides and go-name-extractor helpers that can resolve registered workflow aliases.
• TypeScript generation now supports the notification-service, proto-generic, and proto-oneof WIT examples, including nested generic protobuf payload carriers, required and optional oneofs, and model-only exports with generic transfer converters.
• Generated TypeScript protobuf helpers now use non-null input/output contracts, and oneof switches fail typechecking when a discriminator or variant case is unhandled.

Changed

• Generated protobuf-backed Go models used as eligible top-level Nexus inputs or outputs implement TransferTypeConverter, deferring model conversion to the SDK. Ordinary Nexus models use the public transfer converter API; system Nexus models receive the SDK-selected data converter with the operation's serialization context applied.
• Generated Go request models expose @nexus.source fields as exported fields populated at the operation call site before SDK conversion, making them available to serialization-context helpers.
• Generated TypeScript requiredField helpers are now private to the modules that use them, rather than exported from models.ts; unused definitions are omitted.
• Go convenience wrappers derive function argument grouping and variadic placement from their signatures and primary role, not argument-field names. Signals retain their name-and-single-payload API through explicit Go representation overrides.
• cargo test --all-features no longer requires language-specific toolchains. cargo validate <language> now runs that language's generated-code compilation and runtime regressions alongside its sample checks.
• cargo validate conformance checks JSON Schema behavior across Go, Java, Python, and TypeScript, and is included in full validation.

Fixed

• Render @nexus.doc on WIT variants and their cases in Python, TypeScript, Go, and .NET, including per-language overrides and protobuf oneof-backed cases.
• Go and .NET now honor @nexus.default WIT directives.
• Fix .NET protobuf-backed model conversion for list elements and map values, populating protobuf collections instead of assigning incompatible model collections.
• Fix accidental identifier shadowing in Python transfer converters and Go imports.
• Fix protobuf collection presence metadata; collections don't have presence.
• Preserve @nexus.doc on generated Python WIT record classes, including protobuf-backed and empty records.
• Go generation now selects system Nexus behavior with --system-nexus, not endpoint names.
• Render @nexus.experimental warnings on WIT variants in Python, TypeScript, Go, and .NET without marking individual cases experimental.

nexgen v0.2.9

Added

• Add multiple proto messages to one WIT scaffold with repeated add-message --message, or select all messages in a descriptor-set proto file with --file.
• Go WIT generation supports workflow function name extractors, including registered Temporal workflow names.

Fixed

• Unify add-message and both add-rpc paths so reconciliation restores missing owned fields and declarations throughout reachable mapped records, validates linked records without editing dependencies, and detects oneof case drift while preserving intentional refinements.
• Preserve explicit proto field mappings when generated names do not round-trip; reject unrepresentable oneof member names instead of emitting an invalid mapping.
• Reconcile existing add-message WIT records with selected proto messages, restoring missing records and fields instead of silently returning unchanged output.
