• 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)

• 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)

• 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.

Special thanks to the following individuals for their excellent contributions:

• @ThomasSeliger
• @ribafish

This release introduced support for the distinct attribute in federated search, enabling cross-index distinct attributes with facet distribution support. Additionally, significant performance improvements were delivered, including faster federated search (approximately 100ms faster), optimized JSON document generation for better handling of large documents and a much better memory usage for large workloads.

• Support distinct in federated search by @dureuill in https://github.com/meilisearch/meilisearch/pull/6214

  The distinct attribute can now be passed to the federation object in federated search to apply a global, cross-index and cross-remote distinct computation to the results.

  Example of a federated search request with distinct

   {
     "federation": {
       "distinct": "genres", // ✨ NEW
       "facetsByIndex": { // recovering facet distribution is also supported with distinct
         "comics": [
           "genres"
         ],
         "movies": [
           "genres"
         ]
       },
       "mergeFacets": {} // merging facet distributions is also supported with distinct
     },
     "queries": [
       {
         "indexUid": "comics",
         "q": "batman",
         "attributesToRetrieve": ["title", "genres"],
         "useNetwork": true // distinct is also supported with network queries
       },
       {
         "indexUid": "movies",
         "q": "superman",
         "attributesToRetrieve": ["title", "genres"],
         "useNetwork": true
       }
     ]
   }

       }
     ],
     "processingTimeMs": 15,
     "limit": 5,
     "offset": 0,
     "estimatedTotalHits": 11,
     "facetDistribution": {
       "genres": {
         "Action": 1,
         "Adventure": 1,
         "Comedy": 3,
         "Crime": 2,
         "Documentary": 1,
         "Drama": 1,
         "Family": 1,
         "Fantasy": 1,
         "Horror": 2,
         "Romance": 1,
         "Science Fiction": 1,
         "Thriller": 1,
         "Western": 1
       }
     },
     "facetStats": {},
     "requestUid": "019d05c7-ea65-77a1-8274-22a8ba9e26db",
     "remoteErrors": {}
   }

  Note the following to apply the distinct attribute at the federation level:

  1. Applying distinct at the query level at the same time as the federation level is disallowed and will return a HTTP 400 error.
  2. The chosen distinct field will apply to all remotes and indexes, so it must be a filterable attribute for all participating remotes and indexes.
  3. While Meilisearch attempts to compute the most accurate facet distribution, in distributed contexts this cannot be guaranteed as the distinct algorithm is not applied on all of the remote documents.

• Improve performance of federated search by @dureuill in https://github.com/meilisearch/meilisearch/pull/6229

  Improves performance of federated search: about 100ms faster for all requests. Improves reliability of the HTTP server: the server will no longer be blocked when too many federated search requests are being processed.

• Optimize the generation of JSON documents by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6257

  Addresses performance issues that users might encounter when requesting large documents. Additionally, performance is enhanced when users request only a small subset of fields from large documents.

• Use the latest version of mimalloc to improve memory usage by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6201

  Updates mimalloc from v2 to v3, improving memory sharing between threads and significantly reducing memory usage on large workloads. It also overrides the allocator to use mimalloc at linking time, allowing LMDB, Meilisearch, and other C libraries to share their allocations for better overall memory efficiency. @Kerollmops wrote a blog post about the story behind this improvement.

• Add POST /tasks/compact for task queue compaction by @YoEight in https://github.com/meilisearch/meilisearch/pull/6193

  Compacts the task queue database and reclaim space so new tasks can keep being enqueued, without deleting existing tasks. This feature is behind the taskQueueCompactionRoute experimental feature flag.

[!WARNING]
Once task queue compaction completes, all write operations are blocked until the server is restarted.
