• Added

• GraphQL

• feat(graphql): Add support for ef and distance_threshold in generated GraphQL queries for similarity search (#9562). > WARNING In #9562, the computed distances (automatically returned in the vector_distance > field) for cosine and dot product metrics are no longer normalized to [0, 1], but instead > return the raw distance computed by the metric.

• Vector

• feat(vector/hnsw): add per-query ef and distance_threshold to similar_to, fix early termination (#9514)

• Fixed

• Core

• fix(txn): for lossy indexes, change comparison function to first check the txn cache (#9567)
• fix(cmd): store correct CA verification status (#9554)

• fix(zero): make zero shutdown cleanly (#9525)

• Vector

• fix(vector): Fix similarity-based HNSW search for cosine and dot product metrics (#9559) > WARNING To benefit from the fix in #9559, you must reindex vector predicates that use > cosine or dot product metrics.

• Chore

• docs: fix typos in comments (#9569)
• chore(ci): update go toolchain version to v1.25.6 (#9568)
• fix(ci): update trunk go runtime to match go.mod version (#9575)
• chore(test): replace deprecated docker struct types in testing harness (#9549)
