Release 2.8.0 includes S5–S8 since the previously published 2.4.0.
[2.8.0] - 2026-10-24
Added
- One-way exchange format 1 and CLI snapshot/delta/inspect/apply/status for an
authorized tracked scope on files, Postgres or HTTP and an explicit local
FileStore replica. Source export requires paused writers; apply previews first. - Current envelopes, skill/knowledge content and JSON metadata travel with source
versions, actors and UTC times. Source history bodies, lifecycle records, raw
turns and bindings are excluded. Receivers retain their observed revisions. - Atomic receiver data/erasure/checkpoint recovery, idempotent last-bundle replay,
local conflict detection and explicit stale/out-of-order/missing-checkpoint
refusal. Source gaps or resets require a fresh snapshot in an empty replica. - Exchange schema/guide and independent source-authority, multi-page, corruption,
process-kill, concurrent-apply, physical erasure and Postgres-source contracts.
Compatibility
- Existing format 1, wire 6, Postgres schema 4 and error identifiers remain.
Receiver roots add a private exchange receipt to redo recovery; stop older
writers before upgrading. Full archives remain separate. No remote apply,
bidirectional merge, raw-turn synchronization or managed service is introduced.
[2.7.0] - 2026-10-25
Added
- Durable per-scope change-feed version 1 over CLI, MCP and optional wire-6
routes. Stable event IDs reference memory, skill and shared-knowledge changes,
including rename/delete/erase. Bounded opaque cursors, baseline/restore markers,
explicit retention/reset gaps and operator retention preserve replay semantics. - File memory mutations and scope restores use a private durable redo journal;
the next cooperating storage call recovers interrupted state and event writes.
Postgres couples mutations and events transactionally when its optional
operator-owned changes extension 1 is installed on schema 4. No automatic DDL. - Optional mailbox context pins a mounted current document/version and accepts a
descriptive change ID. Existing operations, occurrence fences and claim leases
remain; references neither copy content nor grant authority or start agents. - Shipped changes guide, schemas and independent replay, concurrent writer,
retention, revoked-authority, process-kill and transaction rollback contracts.
Compatibility
- Existing data formats 1, wire 6, Postgres schema 4 and reserved runtime event
names remain. Stop old writers before upgrading; pause and restart all writers
when installing the Postgres extension. Conversation and whole-batch operations
retain their separate guarantees. References are audit metadata after erasure.
[2.6.0] - 2026-10-24
Added
- Optional governance format 1 for shared procedures and decisions: ownership,
draft/approved/superseded state, content-bound review, UTC effective/expiry
dates and explicit supersession links. Review labels describe attribution;
authenticated scope grants remain authority. - CLI
knowledge govern/read, MCPknowledgeandschema governance.
Review changes prepare source-preserving S5 proposals and use its separate
approval/apply, current-state guards and interrupted-run inspection. - Explicit all/effective/approved retrieval selection, optional profile mount
policies and optional wire-6 knowledge-policy version 1. Filtering precedes
search matching/paging and covers profile memory context and selected skill
graphs. Raw authorized reads/history/export remain inspection surfaces. - Independent review-hash, policy precedence, time-boundary, reference,
revocation and physical erasure contracts across files/Postgres/HTTP, plus
a shipped governance guide. No new storage schema, runtime or host account
model; expiry never deletes content and copied data needs separate erasure.
[2.5.0] - 2026-10-24
Added
upkeep scan/prepare/inspect/apply, MCPupkeep_review/upkeep_applyand
a format-1 proposal schema. Bounded scans flag empty, duplicate, stale-review
and structurally inconsistent memory; the user's agent supplies judgment.- Source-preserving corrections, consolidation, attribute/reference repairs,
retained-revision recovery and aged empty/exact-duplicate deletion. Apply
previews by default and requires a separate approval digest plus current
permissions. Proposals bind logical sources, versions and full snapshots,
including collection rules, metadata and erasure state. - Partial-write receipts and inspection after interrupted or lost-response
outcomes, with stale-proposal refusal and explicit fresh-review recovery.
Apply requires paused writers; no batch atomicity or concurrent-erasure
guarantee is added. Existing formats, wire 6 and Postgres schema 4 remain.
Changed
- The shipped upkeep skill guides proposal review and authorized application.
Legacy deterministic maintenance now also protects sessions, handoff and
collection definitions, including case aliases.
