New Features

• TruncateCollection API: Added TruncateCollection method to the Go SDK client, allowing users to quickly remove all data from a collection without dropping and recreating it. Use NewTruncateCollectionOption(collectionName) to invoke. (#48361, #47308)

• GetReplicateConfiguration API: Added GetReplicateConfiguration API for viewing replication topology (with tokens redacted) and force_promote field to UpdateReplicateConfigurationRequest. Supports strong consistency via WithFreshRead option. (#47543)

• Nullable Pointer Fields in Row-Based API: Go pointer struct fields (*string, *int32, etc.) can now represent nullable columns in the row-based data path. A nil pointer maps to a NULL value in Milvus; a non-nil pointer dereferences to the actual value. This applies to ParseSchema, AnyToColumns, SetField, fillData, and fillPKEntry. (#48464)

• Per-Cluster TLS Config for CDC: Added BuildTLSConfig helper and TLSConfig field to ClientConfig for mTLS support. CDC NewMilvusClient can now read per-cluster TLS config by target cluster ID via GetClusterTLSConfig(clusterID). (#48023)

Bug Fixes

• Timestamptz field type alignment: Fixed FieldTypeTimestamptz value from 15 to 26 to match the server. Changed Timestamptz data serialization from int64 (TimestamptzData) to ISO 8601 strings (RFC3339Nano format via StringData) as expected by the server. Added NewColumnTimestamptz (accepts []time.Time), ColumnTimestampTzIsoString (direct ISO string input), and their nullable counterparts. (#47328)

Improvements

• OpenTelemetry upgrade to v1.40.0: Bumped go.opentelemetry.io/otel and related packages from v1.34.0 to v1.40.0 to fix CWE-426 (Untrusted Search Path) vulnerability. Also bumps transitive dependencies including auto/sdk v1.1.0→v1.2.1, go-logr v1.4.2→v1.4.3, and golang.org/x/sys v0.38.0→v0.40.0. (#48059)

• Go version upgrade to 1.24.12: Upgraded Go from 1.24.11 to 1.24.12 for CVE fixes. (#47562)

• Proto version bumps: Updated milvus-proto/go-api/v2 through v2.6.8 → v2.6.9 → v2.6.10 → v2.6.11 → v2.6.12 → v2.6.13 across this release cycle.
