CHANGELOG

What's new across the stack.

Every release behind Memuron 1.0 and the Arthaanu engineit's built on.

Memuron
v1.1.0
Jun 23, 2026
Retrieval upgrade

Context assembly, URL ingest, and sync

A focused agent-memory upgrade: graph-aware retrieval, prompt-ready context, stable source identity, URL ingest, and a CLI-first local folder sync.

NEWContext assembly. Build bounded prompt blocks with memory citations, relationship citations, and collection breadcrumbs.
NEWURL ingest and folder sync. Fetch public pages or sync local folders into the same document graph.
IMPROVEDGraph-native retrieval. Search can surface link matches, self-loops, parallel edges, and stable source metadata.
Memuron
v1.0.0
Jun 18, 2026
General availability

Memuron 1.0 — a memory layer for agents

The first general release. A typed, linked, multi-tenant memory graph with an LLM ingest pipeline, hybrid retrieval, document understanding, and a native editor integration.

NEWThe Guardian ingest pipeline. Async LLM workflow that retrieves candidates and decides create, update, or link.
NEWHybrid search. Semantic + keyword retrieval fused with reciprocal rank fusion.
NEWMulti-tenant isolation. Hard tenant partitioning enforced at the store.
Arthaanu
v1.0.0
Jun 12, 2026
Engine GA

Arthaanu 1.0 — the engine API

The semantic transduction engine reaches a stable API. Read the docs →

NEWThe A0-A7 planes. A formal separation of external inputs, internal transforms, and derived indices.
NEWEngine API. encode, decode, apply_lifecycle, registries, and ledger access mounted under /engine.
NEWCapability discovery. /runtime/capabilities enumerates registered profiles, types, and tools.
Memuron
v0.9.0
May 30, 2026
Release candidate

MCP server & editor integration

Memuron became reachable straight from AI editors over a streamable MCP server.

NEWMCP tool surface. memuron_query, ingest, get, update, delete, and job polling exposed as typed tools.
NEWClerk OAuth. PKCE flow with dynamic client registration.
IMPROVEDDestructive tool calls now require an explicit confirmation flag.
Memuron
v0.8.0
May 9, 2026
Beta

Documents & the graph

Memories stopped being islands — documents flow into the same traversable graph.

NEWDocument parsing. Multi-format ingest into a typed chunk graph.
NEWGraph traversal & FS queries. Walk neighborhoods, find hubs and paths, and pipe operators over the graph filesystem.
NEWOriginal-source storage. Uploaded files persisted in S3-compatible object storage.
Arthaanu
v0.8.0
Apr 30, 2026
Engine beta

Lifecycles & the projection runtime

Meaning learned to evolve in place, and fast read models became fully rebuildable from the ledger.

NEWLifecycle runtime. Consolidate, supersede, tag, and merge without leaving the ledger.
NEWProjections. Rebuildable lexical, vector, graph, and temporal read models.
IMPROVEDA PostgreSQL backend alongside SQLite, with pgvector backing the vector index.
Memuron
v0.7.0
Apr 21, 2026
Private beta

Spaces, collections & nodes

The organizational primitives that make memory navigable at scale.

NEWSpaces. Segment memory by app, team, or end-user.
NEWNodes & collections. Typed nodes, explicit links, and collection placements.
NEWAsync jobs. Ingest returns a job handle you can poll to completion.
Arthaanu
v0.4.0
Mar 28, 2026
Engine alpha

Encoders, decoders & FastEmbed

Boundary transforms move meaning in and out of the ledger, with embeddings computed locally.

NEWEncoder / decoder runtime. Pluggable write- and read-side transforms with a typed registry.
NEWFastEmbed. Native, local, deterministic embeddings.
NEWRetrieval math. BM25, cosine similarity, and reciprocal rank fusion as reusable primitives.
Arthaanu
v0.1.0
Mar 3, 2026
Foundations

Arthaanu 0.1 — the semantic ledger

The first engine release. Meaning becomes the primary object; everything else is an encoding of it.

NEWArthaStore. Append-only event ledger with identity, history, audit, and replay.
NEWObjects & encodings. A semantic object holds many representations.
NEWTraces. Every transform records provenance.
