Hy-Memory/CHANGELOG.md

Changelog and Release Status

Hy Memory and MemHub are versioned and released independently.

Hy Memory 2.0.5.dev3 — 2026-10-21

• Development preview; not the final 2.0.5 release.
• Published as hy-memory==2.0.5.dev3.
• Lets the existing search API explicitly query SDK raw with layers=["l1_raw"], including existing source filters.

Hy Memory 2.0.5.dev2 — 2026-10-21

• Development preview; not the final 2.0.5 release.
• Published as hy-memory==2.0.5.dev2.
• Adds exact, idempotent semantic-memory import for legacy MemHub cutover without extraction, reconciliation or identity changes.

Hy Memory 2.0.5.dev1 — 2026-10-21

• Development preview for the MemHub SDK-authority migration; this is not the final 2.0.5 release.
• Published as hy-memory==2.0.5.dev1.
• Adds lifecycle status filtering, durable idempotent write outcomes, exact raw APIs, offline local data-plane snapshot/restore, and fail-closed physical delete receipts.

Hy Memory 2.0.3 — 2026-10-17

• Added an optional runtime HTTP transport factory so embedded products can enforce request budgets without wrapping or restricting SDK local-store access.
• Published hy-memory==2.0.3 with unchanged memory extraction, reconciliation, storage, and Coding/Working behavior.

Unreleased

• Removed MemHub's private hy_memory_bridge implementation. MemHub now calls public HyMemoryClient methods through explicit runtime, write, migration, and read modules; prompt/reconcile/response monkey-patches and private VDB/Coding access were deleted. Kuzu Graph projection/admin remains the one documented product exception.
• Extended public SDK get() to resolve Chat, Coding Experience, and Working Fact IDs, including owner/session fields and explicit ambiguity handling; added constructor-time public embedding-service injection.
• Added a MemHub-managed native Hermes MemoryProvider with automatic prefetch, persistent per-session memory-ID deduplication, authorized Broker reads, and recall-context stripping to prevent memory recursion.
• Added an extensible MemHub interface-localization layer with Simplified Chinese, English, and Spanish catalogs shared by Web and Electron-native surfaces. Interface language remains independent from memory content and model processing language.
• search(..., layers=["l1_raw"]) now explicitly searches SDK raw records in pro/ultra mode and keeps existing user/agent/session/source filters; default search continues to hide raw.
• Added import_memory_exact for idempotent migration of an existing semantic memory with its canonical ID, lifecycle and supersession links, without extraction or reconciliation.
• Added SDK-authoritative lifecycle listing with explicit status filters, idempotent durable write outcomes, exact raw import/get/list APIs, and quiesced local data-plane snapshot/restore contracts for the MemHub authority migration.
• Physical delete now reports incomplete VDB/Graph cleanup as a partial failure instead of claiming success after only one store was changed.
• Coding search no longer injects the version-evolution diff block (chain_block) by default. Enable with MEMORY_CODING_CHAIN_BLOCK_ENABLED=true or CodingConfig.chain_block_enabled=True (write-side observe unchanged).
• Fixed governed-memory revisions and repeated evidence links failing when the visibility dirty-marker trigger encounters the same memory twice. Startup now replaces the affected legacy trigger without changing schema versions or governed and visibility data.
• Serialized each SDK SQLite store's shared connection lifecycle so concurrent history/cache operations cannot race with close() and crash the process.
• Scoped Coding reconciliation targets to the current HY authority, conversation, and workspace, preventing near-duplicate sessions from mutating an experience or working fact owned by another evidence context.
• Kept post-write authority verification failures available for read-only reconciliation while preventing automatic or generic confirmed retries from invoking the model again. Automatic reconciliation skips those sticky rows before applying its batch limit, and linked durable jobs exclusively own retry scheduling for their memory tasks.
• Clarified that add(metadata=...) carries legacy SDK processing options, while persistent caller business context belongs in meta.
• Added an opt-in get(..., include_raw=True) path for reading L1_RAW memories, including memories written in lite mode. The default remains hidden for backward compatibility.
• Removed MemHub's task-scoped HyPermission store wrappers and global model-content consent switch. The trusted embedded Hy Memory SDK now uses its native local stores directly.
• Existing installations ignore the retired config flag, readmit previously parked pre-invocation work, and drop only the obsolete hy_node_permissions proof table. Evidence, governed memories, model profiles, SDK stores, and source/host grants are preserved.

Hy Memory 2.0.2 — 2026-10-17

• Published hy-memory==2.0.2 with the current SDK fixes and Apache-2.0 package metadata.

Hy Memory 2.0.1 — 2026-10-16

• Published the Python distribution as hy-memory==2.0.1.
• The repository subsequently adopted the Hy-Memory Apache-2.0 license text. Because PyPI release metadata is immutable, the next SDK patch release must carry the updated license metadata; 2.0.1 retains its published metadata.

MemHub 1.0.3 — Unreleased

• Updated the source version to 1.0.3 (build 7).
• Pinned the public SDK to hy-memory==2.0.3.
• Removed the HyPermission store wrappers and global model-content consent switch; the trusted embedded SDK now uses native local stores.
• Prevented uncertain writes from blocking later source work and added one reconciled automatic retry after ten seconds.
• Added product-facing memory pipeline counters and the log troubleshooting runbook.
• Allowed a verified packaged Desktop Runtime from a different commit to take over an equal-build install atomically while preserving downgrade and tamper refusal.

MemHub 1.0.2 — 2026-10-17

• Updated the source version to 1.0.2 (build 6).
• Pinned the public SDK to hy-memory==2.0.2.
• Pinned onnxruntime==1.23.2 to retain macOS x64 packaging support.
• Fixed relaunch and upgrade failures when a prior managed Runtime exists.
• Embedded canonical build identity when an external packaging pipeline omits release environment fields.
• Added automatic Linux Runtime upload to tagged Draft Releases.

MemHub 1.0.1 — Superseded before release

• The candidate tag was not published as a GitHub Release; 1.0.2 replaces it after the managed-Runtime relaunch fix.

MemHub 1.0.0

• Published the initial GitHub Release with macOS arm64 and Linux Runtime artifacts.
