Changelog

The Emergent Go SDK follows Semantic Versioning and Keep a Changelog.

Source: apps/server/pkg/sdk/CHANGELOG.md

[0.8.0] — Unreleased

Added

Graph ID Model Reform (Issues #43–#47):

  • graphutil package — New pkg/sdk/graph/graphutil/ with IDSet, ObjectIndex, and UniqueByEntity helpers for canonical-aware ID comparison, O(1) lookup by either ID variant, and query result deduplication
  • GetByAnyID method — Semantic alias for GetObject that makes caller intent explicit when the ID could be either version-specific or entity-stable
  • HasRelationship method — Boolean check for relationship existence by type, src, and dst (accepts either ID form)
  • VersionID / EntityID fields — Added to GraphObject and GraphRelationship SDK types alongside deprecated ID / CanonicalID; custom UnmarshalJSON cross-populates all four fields regardless of which names the server sends
  • Dual JSON field names — Server DTOs now emit both id/canonical_id and version_id/entity_id via custom MarshalJSON

Deprecated

  • GraphObject.ID — Use VersionID instead
  • GraphObject.CanonicalID — Use EntityID instead
  • GraphRelationship.ID — Use VersionID instead
  • GraphRelationship.CanonicalID — Use EntityID instead

[0.7.0] — 2026-02-12

Added

Capability Gaps:

  • Template Pack Creation — Full CRUD for template packs via TemplatePacks client
  • Type Schema Registration — Register and retrieve type schemas via TypeRegistry client
  • Property-level Filtering — JSONB PropertyFilter with 9 operators (eq, neq, gt, gte, lt, lte, contains, startsWith, exists) for ListObjects
  • Inverse Relationship Auto-creation — InverseType field on relationships; server auto-creates inverse when set
  • Bulk Object/Relationship Creation — BulkCreateObjects and BulkCreateRelationships (max 100 items, partial-success semantics)

SDK Enhancements:

  • ListTags filtering — ListTagsOptions with Type, Prefix, Limit fields
  • Custom HTTP client — Config.HTTPClient field for custom *http.Client

Fixed

  • SetContext race condition — Added sync.RWMutex to parent Client and all 19 sub-clients
  • ListTags response wrapping — Server now returns {"tags": [...]} instead of bare array
  • Search pagination offset — Added Offset support to FTS, Vector, and Hybrid search
  • SearchWithNeighbors score loss — PrimaryResults now returns SearchWithNeighborsResultItem with both Object and Score

Changed

  • ListTags signature changed from ListTags(ctx) to ListTags(ctx, *ListTagsOptions) — pass nil for previous behavior
  • SearchWithNeighborsResponse.PrimaryResults type changed to []*SearchWithNeighborsResultItem
  • MCP.SetContext signature changed to SetContext(projectID string) (orgID removed)
