v25.3.0-preview-no-maxprocs

This release is an experimental release that removes the hardcoded set of GOMAXPROCS in the shared main module.

Modern go runtimes (>1.25) intelligently use cgroup to determine optimal number of cores to allocate. Also, this change allows one to actually set the GOMAXPROCS env var (previously the call in the main module would have overridden it).

v25.2.0

• 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)
  • chore(test): unskip previously skipped tests (#9537)
  • chore(core): use Tick() instead of NewTicker() (#9548)
