 ## [Unreleased]
 
+## [1.0.57] - 2026-08-06
+
+This stable release promotes the fully delivered `v1.0.57-beta.3` baseline.
+It includes reviewed document shortcuts and chat reply mentions, together with
+the v1.0.57 beta-line command-contract, document, chat, OA, Wiki, compatibility,
+and CI reliability improvements validated through the prerelease channel.
+
+- **Promote v1.0.57-beta.3** — publishes the validated prerelease baseline as
+  the stable `v1.0.57` release without adding post-beta product changes.
+
+## [1.0.57-beta.3] - 2026-08-06
+
+### Added
+
+- **Reviewed document shortcuts** (#880) — adds public document shortcuts for
+  safe local downloads, content and history, review, media and style, and
+  document access/sharing workflows, while retaining reviewed compatibility
+  identities and confirmation safeguards for writes.
+- **Mentions in chat replies** (#881) — `chat message reply` now supports
+  `--at-open-dingtalk-ids` and `--at-all`, forwarding reply mention fields and
+  adding any required mention placeholders without changing existing send
+  behavior.
+
+## [1.0.57-beta.2] - 2026-08-05
+
+### Fixed
+
+- **Stable Chat command compatibility** (#876) — restores the hidden migration
+  entries for `chat send`, `chat history`, and their `im` aliases, preserving
+  the v1.0.56 command surface while directing callers to the supported
+  `chat message send/list` commands. Legacy flags now reach the same migration
+  hints instead of failing during flag parsing.
+- **Drive download cancellation-test stability** (#876) — replaces a
+  timing-sensitive worker-cancellation coverage test with a deterministic seam,
+  reducing flaky CI without changing download behavior.
+
+## [1.0.57-beta.1] - 2026-08-05
+
+This beta starts the v1.0.57 line on top of v1.0.56. It packages the unified
+command-contract and runtime Schema architecture, complete Multi IM Chat
+coverage, document whiteboard and OA approval workflows, Wiki activity feeds,
+and compatibility and CI reliability fixes.
+
+### Added
+
+- **Contact personal-status updates** (#872) — adds `contact user update-ownness`
+  (alias `set-ownness`) for updating a user's personal status text. The write
+  operation maps reviewed `userId` and `ownnessText` parameters to the service
+  contract and requires confirmation unless `--yes` is explicitly supplied.
+- **Document whiteboard workflows** (#861) — adds `doc whiteboard insert`,
+  `whiteboard query/update`, and `doc media upload`. These commands support
+  confirmed document-embedded whiteboard creation and updates, structured
+  OpenNodes reads, and preparation of node-bound Vector/SVG resources.
+- **Complete Multi IM Chat coverage** (#860) — hardens deterministic group and
+  stable-ID resolution, sending, querying, downloading, pagination, and JSON
+  export. The remaining reviewed Chat Shortcuts enter Schema coverage, with
+  destructive delete and clear operations aligned to confirmation gates.
+- **OA approval form workflows** (#853) — adds OA form-schema lookup,
+  process forecast, and confirmed approval-instance creation, supporting both
+  simple flags and complete `--request` payloads.
+- **Wiki activity-feed queries** (#862) — adds `wiki feed list` to retrieve
+  workspace document activity, with cursor paging and optional file exclusion.
+
 ### Changed
 
+- **Unified command and Schema contract framework** (#830) — Leaf commands and
+  Shortcuts now use the shared typed `corecmd` base for flags, constraints,
+  confirmation, Help, and runtime Schema projection. Schema delivery assembles
+  from leaf Contract declarations at runtime; the retired hint overlays,
+  pinned MCP metadata, and committed Catalog artifacts are no longer delivery
+  authorities.
+- **Faster macOS CI without reducing native coverage** (#857) — narrows the
+  macOS race suite to Keychain, codesign, and Darwin-only tests while adding a
+  reachability contract that prevents native-only tests from being silently
+  excluded.
+
+### Fixed
+
+- **Chat media-download JSON compatibility** (#854) — restores parseable
+  `success`, `downloadUrl`, and `output` fields for
+  `chat message download-media --format json` after a successful download,
+  without progress output corrupting JSON stdout.
+
+### Added
+
+- **Document-embedded whiteboard workflows** — adds `doc whiteboard insert` for confirmed creation and part-ID verification, `whiteboard query/update` for structured OpenNodes reads and confirmed writes, and `doc media upload` for preparing node-bound Vector/SVG resources. The public adapter uses an explicit helper-only whiteboard endpoint, validates update envelopes locally, decodes `resultJson`, and publishes the full command, Schema, Skill, and safety contract migrated from `dws-wukong@e2da8ab947c6`.
+
+### Changed
+
+- **Chat reply mentions** — `dws chat message reply` can @ specified group members with `--at-open-dingtalk-ids` or @ everyone with `--at-all`, forwarding the existing `send_personal_message` mention fields and automatically adding missing current-user `<@id>` / `<@all>` placeholders.
 - **Pinned MCP metadata retired** — deletes `internal/cli/schema_mcp_metadata.json` and removes its embed/loader/fallback role from Schema assembly. Catalog now assembles from Contract/ParamDecl/Interface + Cobra only; `make fetch-mcp-metadata` remains an optional diagnostic dump under `artifacts/` and refuses the retired pin path. Policy bans the pin from reappearing.
 - **MCP service review retired** — deletes `schema_mcp_service_review.json` and removes its policy jq / outputguard / test disposition gate (`notify` → `out_of_surface`, snapshot hash pin). No replacement ledger.
 - **Hints retired; ContractDecl is the leaf Schema source** (#830) — `schema_hints/`, Manual/Schema hint overlays, and `schema_agent_metadata/` delivery are removed. Selection, safety, parameters, and interface facts declare on ProductDecl / leaf `Contract` (`corecmd.ContractDecl` + `contract.ParamDecl` / `Safety`). Authoring renamed `SchemaDecl` → `ContractDecl`; nested fields reuse `contract.*` directly.
