 ## [Unreleased]
 
+## [1.0.58] - 2026-08-13
+
+This release promotes the sealed `v1.0.58-beta.6` contents to stable.
+
+### Changed
+
+- **Expanded collaborative workflows** — adds full AI Table, Sheet, Minutes,
+  approval-event, Drive-comment, document export, and CSV workflow support,
+  including safer validation, explicit confirmation for writes, and
+  machine-readable completion receipts.
+- **More capable Chat operations** — adds robot image/file messages, toolbar
+  management, streaming-card mentions, automatic pagination controls, and
+  clearer post-send ID, Markdown-image, paging, and result-shape guidance.
+- **Reliable Agent and CLI contracts** — expands Agent-visible Chat and
+  Minutes commands, aligns bundled skills, improves schema/result envelopes,
+  and hardens parameter, pagination, runtime-token, and write-result
+  verification so ambiguous or incomplete operations fail closed.
+- **Multi-skill install and upgrade** — makes the multi-skill layout the
+  default for fresh installs and upgrades while preserving an explicit legacy
+  mono option.
+- **Safer release delivery** — strengthens release-equivalent compatibility,
+  sealing, package verification, and evaluation-dispatch checks for more
+  reliable cross-platform releases.
+
+## [1.0.58-beta.6] - 2026-08-13
+
+### Fixed
+
+- **npm package verification for multi-skill installs** (#991) — aligns the
+  release verifier with the installer’s concrete Agent skill-root selection,
+  preventing valid multi-skill package layouts from failing release delivery.
+
+### Changed
+
+- **Release-seal CI classification** (#987) — recognizes the reviewed
+  CHANGELOG-and-fragment archival shape while retaining release-contract and
+  lifecycle validation, reducing unrelated CI work for release-seal PRs.
+
+## [1.0.58-beta.5] - 2026-08-13
+
+### Added
+
+- **Agent version and extended context passthrough** (Aone 85384225) — adds
+  validated `DWS_AGENT_VER` and sensitive JSON `DWS_AGENT_EXT` metadata to
+  ordinary non-plugin MCP requests without forwarding it to A2A, OAuth,
+  Discovery, or third-party plugins.
+
+- **Drive file comments** (#961) — adds `dws drive comment list` and `dws drive comment create` for comments on ordinary preview files.
+
+- **Chat automatic pagination controls** (#970) — adds bounded `--max-items` and cancellable `--page-delay` support to the core IM list shortcuts, with safe continuation metadata and truncation reporting.
+
+### Changed
+
+- **Chat message send help** - Clarifies Markdown image syntax for inline mixed text and images.
+
+- **Doc/drive/wiki routing descriptions** — clarifies the document-space container-vs-content boundary across the doc, drive, and wiki skill descriptions for more predictable first-round Agent selection, without changing CLI behavior.

+### Agent Version and Extended Context / Agent 版本与扩展上下文
+
+`DWS_AGENT_VER` and `DWS_AGENT_EXT` are sent only on the CLI's ordinary,
+non-plugin MCP requests. They do not change the standard HTTP `User-Agent` or
+the separate `X-Cli-Version` that identifies the DWS CLI version, and they are
+not forwarded to A2A, OAuth, Discovery, or third-party plugin requests.
+
+`DWS_AGENT_EXT` is one JSON-object Header rather than a set of Headers. The
+recommended keys are `umt`, `miniwua`, and `ua`, but the open-source CLI keeps
+the object extensible and does not enforce a key allowlist. For example, using
+fictional, redacted values:
+
+```bash
+DWS_AGENT_VER=0.1.5
+DWS_AGENT_EXT='{"umt":"example-redacted","miniwua":"example-redacted","ua":"ExampleAgent/0.1.5"}'
+```
+
+The shell's outer single quotes group the JSON and are not part of the
+environment-variable value. The CLI trims surrounding ASCII spaces/tabs,
+omits either Header when its value is empty, and compacts EXT to a single-line
+JSON object. A representative current payload is about 657 bytes, well below
+the 8 KiB limit; integrations must still enforce the limit because values can
+grow. EXT may contain sensitive device or runtime signals: the CLI masks it in
+configuration and logs, and removes it on a cross-host redirect.
+
+Both values are declared by the caller and are therefore forgeable. They can
+support compatibility checks, diagnostics, and observability, but they are not
+credentials or attestations and must never be sufficient on their own to
+authenticate a caller or authorize access.
+
+`DWS_AGENT_VER` 与 `DWS_AGENT_EXT` 仅随 CLI 发起的普通非插件 MCP 请求发送，不会
+改变标准 HTTP `User-Agent`，也不会覆盖标识 DWS CLI 自身版本的 `X-Cli-Version`；
+二者不会进入 A2A、OAuth、Discovery 或第三方插件请求。EXT 使用单个 JSON 对象
+请求头，不拆成多个子请求头；推荐键为 `umt`、`miniwua`、`ua`，但开源 CLI 不限制
+扩展键。Shell 示例中的外层单引号只用于保护 JSON，不属于环境变量值。当前典型负载
+约为 657 字节，远低于 8 KiB 上限，但集成方仍须遵守大小限制。EXT 可能包含敏感的
+设备或运行时信号，配置展示和日志会对其脱敏，跨主机重定向时也会移除该请求头。
+
+这两个值都由调用方自行声明，可以被伪造；它们可用于兼容性判断、诊断和可观测性，
+但不是凭据或可信证明，不能单独用于身份认证或访问授权。
